To pleace an exclusive lock on a file, NFSv4 requires
the file to be opened RW because of the emulation of flock()
by fcntl():
http://www.spinics.net/lists/linux-nfs/msg18502.html
So instead of O_RDONLY, open the file in O_RDWR if access()
indicates it is possible (unless shared lock is requested).

If flock is executed from a process which has set SIGCHLD to SIG_IGN, then
flock will eat cpu and hang indefinitely if given a command to execute.
So before we fork(), make sure to set SIGCHLD handling back to the default
so that the later waitpid() doesn't freak out on us.

With this patch, you can lock directory. Additionally,
lockfile opens with O_NOCTTY.
Try to open file with O_CREAT flag first, and without it
if open fails with EISDIR. Suggested by H. Peter Anvin.
