No need to copy-and-paste lots of boilerplate per string tested, when
we can consolidate that behind helper functions. Plus, this adds a
bit more coverage (we now test all strings both with and without
endptr, whereas before some tests skipped the NULL endptr case), which
exposed a SEGFAULT on qemu_strtosz(NULL, NULL, &val) that will be
fixed in an upcoming patch.
Note that duplicating boilerplate has one advantage lost here - a
failed test tells you which line number failed; but a helper function
does not show the call stack that reached the failure. Since we call
the helper more than once within many of the "unit tests", even the
unit test name doesn't point out which call is failing. But that only
matters when tests fail (they normally pass); at which point I'm
debugging the failures under gdb anyways, so I'm not too worried about
it.

A quick search for 'qemu_strtosz' in the code base shows that outside
of the testsuite, the ONLY place that passes a non-NULL pointer to
@endptr of any variant of a size parser is in hmp.c (the 'o' parser of
monitor_parse_arguments), and that particular caller warns of
"extraneous characters at the end of line" unless the trailing bytes
are purely whitespace. Thus, it makes no semantic difference at the
high level whether we parse "1.5e1k" as "1" + ".5e1" + "k" (an attempt
to use scientific notation in strtod with a scaling suffix of 'k' with
no trailing junk, but which qemu_strtosz says should fail with
EINVAL), or as "1.5e" + "1k" (a valid size with scaling suffix of 'e'
for exabytes, followed by two junk bytes) - either way, any user
passing such a string will get an error message about a parse failure.
However, an upcoming patch to qemu_strtosz will fix other corner case
bugs in handling the fractional portion of a size, and in doing so, it
is easier to declare that qemu_strtosz() itself stops parsing at the
first 'e' rather than blindly consuming whatever strtod() will
recognize. Once that is fixed, the difference will be visible at the
low level (getting a valid parse with trailing garbage when @endptr is
non-NULL, while continuing to get -EINVAL when @endptr is NULL); this
is easier to demonstrate by moving the affected strings from
test_qemu_strtosz_invalid() (which declares them as always -EINVAL) to
test_qemu_strtosz_trailing() (where @endptr affects behavior, for now
with FIXME comments).
Note that a similar argument could be made for having "0x1.5" or
"0x1M" parse as 0x1 with ".5" or "M" as trailing junk, instead of
blindly treating it as -EINVAL; however, as these cases do not suffer
from the same problems as floating point, they are not worth changing
at this time.

It's hard to tweak code for consistency if I can't prove what will or
won't break from those tweaks. Time to add unit tests for
qemu_strtod() and qemu_strtod_finite().
Among other things, I wrote a check whether we have C99 semantics for
strtod("0x1") (which MUST parse hex numbers) rather than C89 (which
must stop parsing at 'x'). These days, I suspect that is okay; but if
it fails CI checks, knowing the difference will help us decide what we
want to do about it. Note that C2x, while not final at the time of
this patch, has been considering whether to make strtol("0b1") parse
as 1 with no slop instead of the C17 parse of 0 with slop "b1"; that
decision may also bleed over to strtod(). But for now, I didn't think
it worth adding unit tests on that front (to strtol or strtod) as
things may still change.
Likewise, there are plenty more corner cases of strtod proper that I
don't explicitly test here, but there are enough unit tests added here
that it covers all the branches reached in our wrappers. In
particular, it demonstrates the difference on when *value is left
uninitialized, which an upcoming patch will normalize.

All the qemu_strto*() functions permit a NULL endptr, just like their
libc counterparts, leaving parse_uint() as the oddball that caused
SEGFAULT on NULL and required the user to call parse_uint_full()
instead. Relax things for consistency, even though the testsuite is
the only impacted caller. Add one more unit test to ensure even
parse_uint_full(NULL, 0, &value) works. This also fixes our code to

It's already confusing that we have two very similar functions for
wrapping the parse of a 64-bit unsigned value, differing mainly on
whether they permit leading '-'. Adjust the signature of parse_uint()
and parse_uint_full() to be like all of qemu_strto*(): put the result
parameter last, use the same types (uint64_t and unsigned long long
have the same width, but are not always the same type), and mark
endptr const (this latter change only affects the rare caller of
parse_uint). Adjust all callers in the tree.
While at it, note that since cutils.c already includes:
QEMU_BUILD_BUG_ON(sizeof(int64_t) != sizeof(long long));
we are guaranteed that the result of parse_uint* cannot exceed
UINT64_MAX (or the build would have failed), so we can drop
pre-existing dead comparisons in opts-visitor.c that were never false.

While we were matching 32-bit strtol in qemu_strtoi, our use of a
64-bit parse was leaking through for some inaccurate answers in
qemu_strtoui in comparison to a 32-bit strtoul (see the unit test for
examples). The comment for that function even described what we have
to do for a correct parse, but didn't implement it correctly: since
strtoull checks for overflow against the wrong values and then
negates, we have to temporarily undo negation before checking for
overflow against our desired value.
Our int wrappers would be a lot easier to write if libc had a
guaranteed 32-bit parser even on platforms with 64-bit long.
Whether we parse C2x binary strings like "0b1000" is currently up to
what libc does; our unit tests intentionally don't cover that at the
moment, though.

We have quite a few undertested and underdocumented integer parsing
corner cases. To ensure that any changes we make in the code are
intentional rather than accidental semantic changes, it is time to add
more unit tests of existing behavior.
In particular, this demonstrates that parse_uint() and qemu_strtou64()
behave differently. For "-0", it's hard to argue why parse_uint needs
to reject it (it's not a negative integer), but the documentation sort
of mentions it; but it is intentional that all other negative values
are treated as ERANGE with value 0 (compared to qemu_strtou64()
treating "-2" as success and UINT64_MAX-1, for example).
Also, when mixing overflow/underflow with a check for no trailing
junk, parse_uint_full favors ERANGE over EINVAL, while qemu_strto[iu]*
favor EINVAL. This behavior is outside the C standard, so we can pick
whatever we want, but it would be nice to be consistent.
Note that C requires that "9223372036854775808" fail strtoll() with
ERANGE/INT64_MAX, but "-9223372036854775808" pass with INT64_MIN; we
weren't testing this. For strtol(), the behavior depends on whether
long is 32- or 64-bits (the cutoff point either being the same as
strtoll() or at "-2147483648"). Meanwhile, C is clear that
"-18446744073709551615" pass stroull() (but not strtoll) with value 1,
even though we want it to fail parse_uint(). And although
qemu_strtoui() has no C counterpart, it makes more sense if we design
it like 32-bit strtoul() (that is, where "-4294967296" be an alternate
acceptable spelling for "1", but "-0xffffffff00000001" should be
treated as overflow and return 0xffffffff rather than 1). We aren't
there yet, so some of the tests added in this patch have FIXME
comments.
However, note that C2x will (likely) be adding a SILENT semantic
change, where C17 strtol("0b1", &ep, 2) returns 0 with ep="b1", but
C2x will have it return 1 with ep="". I did not feel like adding
testing for those corner cases, in part because the next version of C
is not standard and libc support for binary parsing is not yet
wide-spread (as of this patch, glibc.git still misparses bare "0b":
https://sourceware.org/bugzilla/show_bug.cgi?id=30371).

We are inconsistent on the contents of *value after a strto* parse
failure. I found the following behaviors:
- parse_uint() and parse_uint_full(), which document that *value is
slammed to 0 on all EINVAL failures and 0 or UINT_MAX on ERANGE
failures, and has unit tests for that (note that parse_uint requires
non-NULL endptr, and does not fail with EINVAL for trailing junk)
- qemu_strtosz(), which leaves *value untouched on all failures (both
EINVAL and ERANGE), and has unit tests but not documentation for
that
- qemu_strtoi() and other integral friends, which document *value on
ERANGE failures but is unspecified on EINVAL (other than implicitly
by comparison to libc strto*); there, *value is untouched for NULL
string, slammed to 0 on no conversion, and left at the prefix value
on NULL endptr; unit tests do not consistently check the value
- qemu_strtod(), which documents *value on ERANGE failures but is
unspecified on EINVAL; there, *value is untouched for NULL string,
slammed to 0.0 for no conversion, and left at the prefix value on
NULL endptr; there are no unit tests (other than indirectly through
qemu_strtosz)
- qemu_strtod_finite(), which documents *value on ERANGE failures but
is unspecified on EINVAL; there, *value is left at the prefix for
'inf' or 'nan' and untouched in all other cases; there are no unit
tests (other than indirectly through qemu_strtosz)
Upcoming patches will change behaviors for consistency, but it's best
to first have more unit test coverage to see the impact of those
changes.

glib documentation[1] is clear: g_assert() should be avoided in unit
tests because it is ineffective if G_DISABLE_ASSERT is defined; unit
tests should stick to constructs based on g_assert_true() instead.
Note that since commit 262a69f428, we intentionally state that you
cannot define G_DISABLE_ASSERT while building qemu; but our code can
be copied to other projects without that restriction, so we should be
consistent.
For most of the replacements in this patch, using g_assert_cmpstr()
would be a regression in quality - although it would helpfully display
the string contents of both pointers on test failure, here, we really
do care about pointer equality, not just string content equality. But
when a NULL pointer is expected, g_assert_null works fine.

In the past, commit a231cb27 ("iotests: Fix 104 for NBD", v2.3.0)
added an additional filter to _filter_img_info to rewrite NBD URIs
into the expected output form. This recently broke when we tweaked
tests to run in a per-format directory, which did not match the regex,
because _img_info itself is now already changing
SOCK_DIR=/tmp/tmpphjfbphd/raw-nbd-104 into
/tmp/tmpphjfbphd/IMGFMT-nbd-104 prior to _img_info_filter getting a
chance to further filter things.
While diagnosing the problem, I also noticed some filter lines
rendered completely useless by a typo when we switched from TCP to
Unix sockets for NBD (in shell, '\\+' is different from "\\+" (one
gives two backslash to the regex, matching the literal 2-byte sequence
<\+> after a single digit; the other gives one backslash to the regex,
as the metacharacter \+ to match one or more of <[0-9]>); since the
literal string <nbd://127.0.0.1:0\+> is not a valid URI, that regex
hasn't been matching anything for years so it is fine to just drop it
rather than fix the typo.

All callers now pass is_external=false to aio_set_fd_handler() and
aio_set_event_notifier(). The aio_disable_external() API that
temporarily disables fd handlers that were registered is_external=true
is therefore dead code.
Remove aio_disable_external(), aio_enable_external(), and the
is_external arguments to aio_set_fd_handler() and
aio_set_event_notifier().
The entire test-fdmon-epoll test is removed because its sole purpose was
testing aio_disable_external().

For simplicity, always run BlockDevOps .drained_begin/end/poll()
callbacks in the main loop thread. This makes it easier to implement the
callbacks and avoids extra locks.
Move the function pointer declarations from the I/O Code section to the
Global State section for BlockDevOps, BdrvChildClass, and BlockDriver.
Narrow IO_OR_GS_CODE() to GLOBAL_STATE_CODE() where appropriate.
The test-bdrv-drain test case calls bdrv_drain() from an IOThread. This
is now only allowed from coroutine context, so update the test case to
run in a coroutine.

POWER9 DD2.1 and earlier had significant limitations when running KVM,
including lack of "mixed mode" MMU support (ability to run HPT and RPT
mode on threads of the same core), and a translation prefetch issue
which is worked around by disabling "AIL" mode for the guest.
These processors are not widely available, and it's difficult to deal
with all these quirks in qemu +/- KVM, so create a POWER9 DD2.2 CPU
and make it the default POWER9 CPU.

The order in which instructions are generated by gen_insn() influences
assignment to tmp registers. During generation, tmp instructions (e.g.
generate_V6_vassign_tmp) use vreg_src_off() to determine what kind of
register to use as source. If some instruction (e.g.
generate_V6_vmpyowh_64_acc) uses a tmp register but is generated prior
to the corresponding tmp instruction, the vregs_updated_tmp bit map
isn't updated in time.
Exmple:
{ v14.tmp = v16; v25 = v14 } This works properly because
generate_V6_vassign_tmp is generated before generate_V6_vassign
and the bit map is updated.
{ v15:14.tmp = vcombine(v21, v16); v25:24 += vmpyo(v18.w,v14.h) }
This does not work properly because vmpyo is generated before
vcombine and therefore the bit map does not yet know that there's
a tmp register.
The parentheses in the decoding function were in the wrong place.
Moving them to the correct location makes shuffling of .tmp vector
registers work as expected.

We recently moved glib detection code to meson but this changes the
linker command line from -lglib-2.0 to using a path to libglib-2.0.so.
This does not work for static linking, which is used by stress.c:
$ make V=1 tests/migration/initrd-stress.img
cc -m64 -mcx16 -o tests/migration/stress ... -static -Wl,--start-group
/usr/lib64/libglib-2.0.so -Wl,--end-group
...
bin/ld: attempted static link of dynamic object `/usr/lib64/libglib-2.0.so'
Add a specific dependency for stress.c, which is linked statically.
The compiler command line is now:

-Wl,--start-group -lm /usr/lib64/libpcre.a -lglib-2.0 -Wl,--end-group

We cannot use the generic reentrancy guard in the LSI code, so
we have to manually prevent endless reentrancy here. The problematic
lsi_execute_script() function has already a way to detect whether
too many instructions have been executed - we just have to slightly
change the logic here that it also takes into account if the function
has been called too often in a reentrant way.
The code in fuzz-lsi53c895a-test.c has been taken from an earlier
patch by Mauro Matteo Cascella.

for testing whether the rtl8139 device is available or not, this is not
enough: The CONFIG switch might have been selected by another target
(e.g. the mips fuloong2e machine has the rtl8139 chip soldered on the
board), so CONFIG_RTL8139_PCI ends up in config_all_devices and the
test then gets executed on x86. We need an additional run-time check
to be on the safe side to make this test also work when configure has

Clean up monitor_event to just use monitor_suspend/monitor_resume,
using mon->mux_out to protect against incorrect nesting (especially
on startup).
The only remaining case of reading suspend_cnt is in the can_read
callback, which is just advisory and can use qatomic_read.
As an extra benefit, mux_out is now simply protected by mon_lock.
Also, moving the prompt to the beginning of the main loop removes
it from the output in some error cases where QEMU does not actually
start successfully. It is not a full fix and it would be nice to
also remove the monitor heading, but this is already a small (though
unintentional) improvement.
