* Added [un]lock_memory_etc() versions that accept a team_id as first argument.

Browse Source 
This allows drivers to lock the memory outside of the original team context.
* create_area_etc() got a struct team as first argument, but that should have
  been a team_id.
* Removed delete_area_etc() - there is already vm_delete_area() doing the same
  thing.
* Renamed vm_get_address_space_by_id() to vm_get_address_space(), as there is
  no other method of getting an address space.
* Removed erroneous white space.
