Modified files:
sys/kern kern_descrip.c kern_fork.c
Log:
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
