- Relaxed the Virtual Memory Reservation to allow pStart and not fail if
the pStart value is not obtained.
- Moves checks on pStart to the user to check and determine if they want
to re-reserve or use the address allocated.
- Changed reserveGpuAddress to use unit64_t type to allow internal
address range structure assignment without cast.

physical mapping with a lookup function for reserved virtual addresses.
- Added support for multiple mappings linked to the same virtual
reservation.

properly check for the error and propagate it upwards.

This change replaces unneeded copying of std::vectors
with usage of const references. Furthermore, it adds
reserve() call before filling the container via push_back().

in long running application (a lot of allocations) we will observe
memory leak.
