        setuidgid: set all groups, not just the primary one.
        I wanted to use the xgetgroups function from id.c, so factored
        it out and made it into a non-exiting function (hence the "m"
        prefix rather than "x").
        * src/setuidgid.c (main): Use mgetgroups.
        Include "mgetgroups.h".

        * src/id.c (xgetgroups): Remove function.
        Include "mgetgroups.h".
        (print_group_list): Use mgetgroups, not xgetgroups.

        * gl/modules/mgetgroups: New module.
        * gl/lib/mgetgroups.c: New file.  mgetgroups is derived from
        id.c's xgetgroups function.
        * bootstrap.conf (gnulib_modules): Add mgetgroups.
        * gl/m4/mgetgroups.m4: New file.
        * gl/lib/mgetgroups.h: New file.

        * bootstrap: Merge in changes from gnulib.

        * src/id.c: Include "getugroups.h" rather than declaring manually.
