Support Mapping Multiple Physical Memory with one VA and Bug Fix

Browse Source 
- Added support for mapping any portion of a virtual allocation to a
physical mapping with a lookup function for reserved virtual addresses.
- Added support for multiple mappings linked to the same virtual
reservation.
- Fixed bug with 64 bit addresses on windows with invalid addresses
passed to the user.
