This patch moves definitions of Windows dump structures to
include/qemu/win_dump_defs.h to keep create_win_dump() prototype separate.

Unlike dying Windows, live system memory doesn't contain
correct register contexts. But they can be populated with QEMU register
values.
After this patch, QEMU will be able to produce guest Windows live system
dump.

This patch adds Windows crashdumping feature. Now QEMU can produce ELF-dump
containing Windows crashdump header, which can help to convert to a valid
WinDbg-understandable crashdump file, or immediately create such file.
The crashdump will be obtained by joining physical memory dump and 8K header
exposed through vmcoreinfo/fw_cfg device by guest driver at BSOD time. Option
'-w' was added to dump-guest-memory command. At the moment, only x64
configuration is supported.
Suitable driver can be found at
