Subject: Add four utility functions related to struct grp processing modeled
 in-part after similar calls related to struct pwd in libutil/pw_util.c:   -
 gr_equal()     Perform a deep comparison of two struct grp's.  It does a
 thorough, yet     unoptimized comparison of all the members regardless of
 order.

  - gr_make()
    Create a string (see group(5)) from a struct grp.

  - gr_dup()
    Duplicate a struct grp.  Returns a value that is a single contiguous
    block of memory.

  - gr_scan()
    Create a struct grp from a string (as produced by gr_make()).
