thorpej 76589fafd4 - uvmspace_share(): If p2 has a vmspace already, make sure to deactivate
it and free it as appropriate.  Activate p2's new address space once
  it references p1's.
- uvm_fork(): Make sure the child's vmspace is NULL before calling
  uvmspace_share() (the child doens't have one already in this case).

These changes do not change the behavior for the current use of
uvmspace_share() (vfork(2)), but make it possible for an already
running process (such as a kernel thread) to properly attach to
another process's address space.
