  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.
