commit 2281ff2e747640a3804f657da1ffadfb3f93eb75

    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.
