mgetgroups: add xgetgroups, and avoid ENOSYS failures
ENOSYS implies that there are no supplemental groups, so we can
treat it the same as a return of 0 from getgroups rather than
exposing failure to the user. This in turn fixes a crash in
coreutils' id, which freed an uninitialized pointer.
* lib/mgetgroups.h (xgetgroups): New prototype.
* lib/mgetgroups.c (xgetgroups): New wrapper.
(mgetgroups): Handle ENOSYS.
* modules/mgetgroups (Depends-on): Add realloc.

mgetgroups: new module, taken from coreutils
Wrapper function that makes using getgroups/getugroups easier to use.
As part of the move from coreutils, convert GETGROUPS_T to gid_t,
and allow mgetgroups(NULL,getegid(),&list) as a way to ensure that
the effective gid is in the list.
* modules/mgetgroups: New file.
* lib/mgetgroups.h: Likewise.
* lib/mgetgroups.c (mgetgroups): Likewise.
* m4/mgetgroups.m4 (gl_MGETGROUPS): Likewise.
* MODULES.html.sh (Users and groups): Mention it.
