mspatcha: Partially implement ApplyPatchToFileW and related functions.

This can patch non-executables and 64-bit executable files, but
patching of 32-bit executables is not supported. They are subject to
special processing which alters PE relocations to match with those in
the old file to improve compression. To reverse this, the meaning of
the decoding data must be interpreted. Details, including where to
find that data in the patch file, are included in pa19.c. Interleaved
decompression of large files is also not supported.
