2018-06-29dump: add Windows live system dumpViktor Prutyanov1-3/+92
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.

2018-06-29dump: add Windows dump format to dump-guest-memoryViktor Prutyanov1-0/+87
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.
