First rev at making pipe(2) pipe's MPsafe.

Both ends of the pipe share a pool_mutex, this makes allocation
and deadlock avoidance easy.

Remove some un-needed FILE_LOCK ops while I'm here.

There are some issues wrt to select and the f{s,g}etown code that
we'll have to deal with, I think we may also need to move the calls
to vfs_timestamp outside of the sections covered by PIPE_LOCK.
