description:
Add entry for flock() syscall.

>From the NetBSD and OSF man pages, the arguments and operation of the
2 flocks are identical.  The only differences are in some of the possible
values for errno which may be set in the event of certain errors.  These
differences are (again from the manual pages):

The NetBSD flock may set errno to

     [EOPNOTSUPP]  The argument fd refers to an object other than a file.

and the OSF flock doesn't list this is a possible error code.

The OSF flock may set errno to:

  [EINTR]   A signal interuppted the flock call.
  [ENOLCK]  The lock table is full.  Too many regions are already locked.
  [EDEADLK] The lock is blocked by some lock from another process.  Putting
            the calling process to sleep while waiting for that lock to
            become free would cause a deadlock.

while the NetBSD flock does not list these as possibilities.

The remainder of the possible error codes are the same.

commit cleared with thorpej first.
