* Merged vm_virtual_map with vm_address_space - there was no reason to have

them apart (this even saves a pointer from vm_virtual_map to its address space)
* aspace -> address_space
* vm_create_address_space() did not check if creating the semaphore succeeded
* Removed team::kaspace - was not really needed (introduced a new vm_kernel_address_space()
  function that doesn't grab a reference to the address space)
* Removed vm_address_space::name - it was just a copy of the team name, anyway,
  and there is always only one address space per team
* Removed aspace_id - the address space is now using the team_id
* Some cleanup.
