(do_lookup_alias): Split out from __gconv_find_transform. (__gconv_find_transform): Call do_lookup_alias. (__gconv_loopup_alias): New function. * locale/langinfo.h: Define _NL_*_CODESET values for all categories but LC_CTYPE. * locale/categories.def: Add entries for new _NL_*_CODESET values. * locale/C-ctype.c: Use _nl_C_codeset to initialize CODESET entry. * locale/C-address.c: Initialize _NL_*_CODESET element. * locale/C-collate.c: Likewise. * locale/C-identification.c: Likewise. * locale/C-measurement.c: Likewise. * locale/C-messages.c: Likewise. * locale/C-monetary.c: Likewise. * locale/C-name.c: Likewise. * locale/C-numeric.c: Likewise. * locale/C-paper.c: Likewise. * locale/C-telephone.c: Likewise. * locale/C-time.c: Likewise. * locale/localeinfo.h: Declare _nl_C_codeset. * locale/C_name.c: Define _nl_C_codeset. * locale/findlocale.c: Before accepting locale check that the used charset does not conflict with what the locale name said. * locale/programs/ld-address.c: Emit codeset information. * locale/programs/ld-collate.c: Likewise. * locale/programs/ld-identification.c: Likewise. * locale/programs/ld-measurement.c: Likewise. * locale/programs/ld-messages.c: Likewise. * locale/programs/ld-monetary.c: Likewise. * locale/programs/ld-name.c: Likewise. * locale/programs/ld-numeric.c: Likewise. * locale/programs/ld-paper.c: Likewise. * locale/programs/ld-telephone.c: Likewise. * locale/programs/ld-time.c: Likewise. * localedata/tests-mbwc/tst_funcs.h (TST_HEAD_LOCALE): It is an error if the locale data couldn't be found. * string/Makefile: Define tst-strxfrm-ENV. * ysdeps/unix/sysv/linux/ia64/getcontext.S: Fix comment.
