* Introduced structures {virtual,physical}_address_restrictions, which specify

restrictions for virtual/physical addresses.
* vm_page_allocate_page_run():
  - Fixed conversion of base/limit to array indexes. sPhysicalPageOffset was not
    taken into account.
  - Takes a physical_address_restrictions instead of base/limit and also
    supports alignment and boundary restrictions, now.
* map_backing_store(), VM[User,Kernel]AddressSpace::InsertArea()/
  ReserveAddressRange() take a virtual_address_restrictions parameter, now. They
  also support an alignment independent from the range size.
* create_area_etc(), vm_create_anonymous_area(): Take
  {virtual,physical}_address_restrictions parameters, now.
* Removed no longer needed B_PHYSICAL_BASE_ADDRESS.
* DMAResources:
  - Fixed potential overflows of uint32 when initializing from device node
    attributes.
  - Fixed bounce buffer creation TODOs: By using create_area_etc() with the
    new restrictions parameters we can directly support physical high address,
    boundary, and alignment.
