* inet/getnetgrent_r.c (endnetgrent, __getnetgrent_r): Actually call
the static symbols added in the last change (doofus is me).
* locale/newlocale.c (__newlocale): Use a bit mask instead of a second
loop to notice missing categories in a composite name.
* locale/locale.h (LC_CTYPE_MASK, LC_NUMERIC_MASK, LC_TIME_MASK,
LC_COLLATE_MASK, LC_MONETARY_MASK, LC_MESSAGES_MASK, LC_ALL_MASK,
LC_PAPER_MASK, LC_NAME_MASK, LC_ADDRESS_MASK, LC_TELEPHONE_MASK,
LC_MEASUREMENT_MASK, LC_IDENTIFICATION_MASK, LC_ALL_MASK): New macros.
* malloc/tst-calloc.c: Add tests for one or both parameters being zero.
