Mapped file utility functions

Module Description

Convenience functions for HMAPFILE...

These are not quite necessary, since you can just memcpy from the file's PBYTE,
but sometimes it makes life easier to wrap your noggin around the age-old paradigm
of reading a file and having the RTL remember the file's current position.
FWIW, these have SEH (if the compiler supports it).

Functions
size_t	PeekMappedFile (HMAPFILE hMapFile, PVOID Buffer, size_t cbRead)
size_t	ReadMappedFile (HMAPFILE hMapFile, PVOID Buffer, size_t cbRead)
size_t	WriteMappedFile (HMAPFILE hMapFile, PVOID Buffer, size_t cbWrite)
PBYTE	GetMappedFilePtr (HMAPFILE hMapFile)
PBYTE	SetMappedFilePtr (HMAPFILE hMapFile, INT64 Offset, UINT How)
UINT64	GetMappedFilePos (HMAPFILE hMapFile)
UINT64	SetMappedFilePos (HMAPFILE hMapFile, INT64 Offset, UINT How)
