Summary:                    Implement flock
Description: 
I've ported H. Peter Anvin's flock implementation
(http://directory.fsf.org/All/flock.html) to BusyBox.  This utility is
handy for implementing mutual exclusion in shell scripts.

The attached patch is a rough first draft.  It works, but segfaults if the
fd# argument is missing.  I would appreciate suggestions for improvements,
especially for making option processing and usage more BusyBox-like.
