The biggest change is to rename its prefix from BDRV_IOS to
BLOCK_DEVICE_IO_STATUS.
Next commit will convert the query-block command to the QAPI
and that's how the enumeration is going to be generated.

A future commit will convert bdrv_info() to the QAPI and it won't
provide IOS_INVAL.
Luckily all we have to do is to add a new 'iostatus_enabled'
member to BlockDriverState and use it instead.

Today we generate something like this:
int qmp_marshal_input_query_foo(...)
...
retval = qmp_query_foo(errp);
qmp_marshal_output_query_foo(retval, ret, errp);
...
However, if qmp_query_foo() fails 'retval' will probably be NULL,
which can cause a segfault as not all visitors check if 'retval'
is valid.
This commit fixes that by changing the code generator to only
call the output marshal if qmp_query_foo() succeeds, like this:
retval = qmp_query_foo(errp);
if (!error_is_set(errp)) {
qmp_marshal_output_query_foo(retval, ret, errp);
}

Use target_ulong instead of hard-coded uint32_t.
Remove the disabled printf's that are redundant with -strace.

Don't confuse the load address with the load bias. They're equal
for ET_DYN objects (i.e. ld.so) but different for ET_EXEC objects
(i.e. statically linked).

For OBS, we're running a full cross-guest inside of a VM. When a build
is done there, we reboot the guest as shutdown mechanism.
Unfortunately, reboot is not implemented in linux-user. So this mechanism
fails, spilling unpretty warnings. This patch implements sys_reboot()
emulation.

When running openat using qemu-arm, we stumbled over invalid permissions
on the created files. The reason for this is that the mode parameter gets
treates as an O_... flag, which it isn't - it's a permission bitmask.
This patch removes the needless translation of the mode parameter,
rendering permission passing of openat() to work with linux-user.

While ALIGNADDR was implemented out-of-line, ALIGNADDRL was not
implemeneted at all. However, this is a very simple operation
so we're better off doing this inline.

This reduces the size of the individual translation blocks, since
we only emit a single call for each FOP rather than three. In
addition, clear_float_exceptions expands inline to a single byte store.

This allows a more efficient representation for 64-bit hosts.
It should be about the same for 32-bit hosts, as we can still
access the individual pieces of the double.

Begin using i64 quantities to manipulate double-precision values.
On a 64-bit host this will, for the moment, generate less efficient
code; on a 32-bit host code quality should be largely unchanged.
Code quality for 64-bit will be adjusted with a subsequent patch.

Load, store, and "create destination". This version attempts to
change the behaviour of the translator as little as possible. We
previously used cpu_tmp32 as the temporary destination, and we
continue to use that. This will eventually allow a change in
representation of the fprs.
Change the name of the cpu_fpr array to make certain that all
instances are converted.
