tegge f360480a68 Avoid file lock leakage when linuxthreads port or rfork is used: 
- Mark the process leader as having an advisory lock
  - Check if process leader is marked as having advisory lock when
    closing file
  - Check that file is still open after lock has been obtained
  - Don't allow file descriptor table sharing between processes
    with different leaders
