Scott Graham 019a0cec8b win: Write memory map info as MINIDUMP_MEMORY_INFO[_LIST]
Makes !vprot work in windbg, e.g.

0:000> !vprot 0x970000
BaseAddress:       00970000
AllocationBase:    00970000
AllocationProtect: 00000004  PAGE_READWRITE
RegionSize:        00001000
State:             00001000  MEM_COMMIT
Protect:           00000001  PAGE_NOACCESS
Type:              00020000  MEM_PRIVATE
