* Changed some parameters of VM syscalls from int to uint32, mostly for sake

of consistency.
* Moved the B_OVERCOMMITTING_AREA flag from B_KERNEL_AREA_FLAGS to
  B_USER_AREA_FLAGS, since we really allow it to be passed from userland.
* Most VM syscalls check the provided protection against B_USER_AREA_FLAGS
  instead of B_USER_PROTECTION, now. This way they allow for
  B_OVERCOMMITTING_AREA as well.
* _user_map_file(), _user_set_memory_protection(): Check the protection like
  the other syscalls do and use fix_protection() instead of doing that
  manually.
