mgetgroups: remove dependency on realloc-gnu
The dependency violates the comment in realloc-gnu, which
says that tests can't depend on realloc-gnu; some tests depend
on mgetgroups, so mgetgroups can't depend on realloc-gnu.
Problem reported by Daniel Richard G. in
<http://lists.gnu.org/archive/html/bug-gnulib/2013-10/msg00056.html>.
* lib/mgetgroups.c (mgetgroups): Don't call realloc (NULL, 0).
* modules/mgetgroups (Depends-on): Depend on realloc-posix,
not realloc-gnu.

mgetgroups: relax license to LGPLv2+
getgrouplist is part of glibc and LGPLv2+; the mgetgroups module
is merely an ease-of-use wrapper around this interface. There's
nothing in the algorithm worth protecting by the more-restrictive
GPLv3+. See also this thread.
https://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00092.html
* modules/getugroups (License): Change from GPLv3+.
* modules/mgetgroups (License): Likewise.
* modules/getgroups (License): Change from LGPLv3+.

hash, mgetgroups: drop xalloc dependency
Rely on the new xalloc-oversized module to avoid requiring
xalloc-die for functions documented as returning NULL on
potential allocation overflow.
* lib/hash.c (includes): Adjust includes.
* lib/mgetgroups.c (includes): Likewise.
(xgetgroups): Move...
* lib/xgetgroups.c: ...to new file.
* modules/xgetgroups: New file, split from...
* modules/mgetgroups: ...here.
(Depends-on): Add xalloc-oversized.
* modules/hash (Depends-on): Likewise.
* modules/hash-tests (Depends-on): Drop xalloc.
(test_hash_LDADD): Drop unused library.
* tests/test-hash.c (main): Break xalloc dependency.
(includes): Drop unused include.

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.
