Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

The gthread coroutine backend is broken and does not produce a working
QEMU; it is only useful for some very limited debugging situations.
Clean up the backend selection logic in configure so that it now runs
"if on windows use windows; else prefer ucontext; else sigaltstack".
To do this we refactor the configure code to separate out "test
whether we have a working ucontext", "pick a default if user didn't
specify" and "validate that user didn't specify something invalid",
rather than having all three of these run together. We also simplify
the Makefile logic so it just links in the backend the configure
script selects.

Provide a convenience function for reporting an error and exiting,
and update various places in the configure script to use it.
This allows us to be a little more consistent about how format
our error messages and makes the calling code shorter.

I misread the glib manual, g_source_remove does not let you re-attach
the source later. This behavior (called "blocking" the source in glib)
is present in glib's source code, but private and not available outside
glib; hence, we have to resort to re-creating the source every time.
In fact, g_source_remove and g_source_destroy are the same thing,
except g_source_destroy is O(1) while g_source_remove scans a potentially
very long list of GSources in the current main loop. Ugh. Better
use g_source_destroy explicitly, and leave "tags" to those dummies who
cannot track their pointers' lifetimes.

iPXE vmxnet3 driver makes a few assumptions regarding device operation
that were missed during testing with Linux and Windows drivers.
This patch adds following logic:
1. Additional GET commands processing added
2. Max number of RX chunks should be set to 1 when driver passes 0
via corresponding shared memory field
3. Enforecement for max chunks number added

This can save one insn, if the constant has any bits in 32-63 set,
but no bits in 21-31 set. It never results in more insns.

Since we're always in 64-bit mode, load address performs a full
64-bit add. Use that for 3-address addition, as well as for
larger constant addends when we lack extended-immediates facility.

Since we have a free temporary and can always just load the constant, we
ought to do so, rather than spending the same effort constraining the const.
