We should map and use guest memory run by parts if it can't be mapped as
a whole.
After this patch, continuos guest physical memory blocks which are not
continuos in host virtual address space will be processed correctly.

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.

KdDebuggerDataBlock may be encrypted in guest memory and dump will be
useless in this case. But guest driver can obtain decrypted KDBG and
expose its address through BugcheckParameter1 field in raw header.
After this patch, QEMU will be able to use fallback KdDebuggerDataBlock.

We use CPU #0 to access guest virtual memory, but it can execute user
thread at that moment. So, switch CR3 to PageDirectoryBase from header
and restore original value at the end.

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
