* *.c (*): initialize lock_arg to a copy of a static
(thus zero) struct flock, to avoid panic'ing sunos 4.1.4.
If you call fcntl F_SETLKW with l_type == F_UNLCK and l_xxx == 15
(GRANT_LOCK_FLAG) you'll panic sunos 4.1.4 with
assertion failed: ld->l_xxx != GRANT_LOCK_FLAG, file: ../../ufs/ufs_lockf.c, line: 995
Since automatic structs like these have random values in uninitialized
fields, we initialize from a static struct (since using memset in this
case is abhorrent, and naming l_xxx is non POSIX.)
