972448628a dump: Add create_win_dump() stub for non-x86 targets
Implement the non-x86 create_win_dump(). We can remove
the last TARGET_X86_64 #ifdef'ry in dump.c, which thus
becomes target-independent. Update meson accordingly.

efc3146a6e dump: Simplify compiling win_dump.o by introducing win_dump_available()
To make dump.c less target dependent, move the TARGET_X86_64 #ifdef'ry
from dump.c to win_dump.c (introducing a win_dump_available() method
there). By doing so we can build win_dump.c on any target, and
simplify the meson rule.

ac978771e4 dump: Clean included headers
"qemu/win_dump_defs.h" is only required by win_dump.c,
but win_dump.h requires "sysemu/dump.h" which declares
the DumpState type. Remove various unused headers.

e38c24cb58 dump/win_dump: limit number of processed PRCBs
When number of CPUs utilized by guest Windows is less than defined in
QEMU (i.e., desktop versions of Windows severely limits number of CPU
sockets), patch_and_save_context routine accesses non-existent PRCB and
fails. So, limit number of processed PRCBs by NumberProcessors taken
from guest Windows driver.

f5daa8293b dump/win_dump: add 32-bit guest Windows support
Before this patch, 'dump-guest-memory -w' was accepting only 64-bit
dump header provided by guest through vmcoreinfo and thus was unable
to produce 32-bit guest Windows dump. So, add 32-bit guest Windows
dumping support.

Instead, use warn_report().

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.
