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.
