kernel - More tty and devfs race fixes

* Refactor the unix98 pty code to consolidate termination handling and
  add flags to deal with close() races.

* Rename devfs_clone_bitmap_rst() to devfs_clone_bitmap_put()

* devfs_clone_bitmap_put() now syncs devfs messages before clearing
  the bitmap bit, to ensure that related destroy_dev()s complete
  before the unit number becomes available for a new allocation
  again.
