[Bug-gnulib] getgroups.c merge from coreutils

[Paul Eggert]

I installed this patch from coreutils:

2003-08-04  Paul Eggert  <address@hidden>

        Merge from coreutils.
        * getgroups.c: Include "xalloc.h" instead of declaring xalloc fns;
        from Dmitry V. Levin.
        Remove anachronistic cast of xrealloc.
