locks: Allow disabling mandatory locking at compile time
Mandatory locking appears to be almost unused and buggy and there
appears no real interest in doing anything with it. Since effectively
no one uses the code and since the code is buggy let's allow it to be
disabled at compile time. I would just suggest removing the code but
undoubtedly that will break some piece of userspace code somewhere.
For the distributions that don't care about this piece of code
this gives a nice starting point to make mandatory locking go away.
