mmap: Fix size restriction of maps due to using 32 bit size type

Browse Source 
Throughout mmap, size-related variables and parameters are still using
DWORD as type, which disallows mapping ranges > 4Gigs.  Fix this by
using SIZE_T throughout for those vars and parameters.
Also, drop unused off parameter from 1st variant of mmap_record::map_pages.
