Abbreviated alternative month names (%Ob) also added (bug 10871).

All the previous changes also repeated to support abbreviated alternative month names. In most languages which have declension and need nominative/genitive month names the abbreviated forms for both cases are the same. An example where they do differ is May in Russian: this name is too short to be abbreviated so even the abbreviated form features the declension suffixes. [BZ #10871] * locale/C-time.c (_nl_C_LC_TIME): Add abbreviated alternative month names, define them as the same as abbreviated month names explicitly. * locale/categories.def (LC_TIME): Add ab_alt_mon and wide-ab_alt_mon. * locale/langinfo.h: (_NL_ABALTMON_1, _NL_ABALTMON_2, _NL_ABALTMON_3, _NL_ABALTMON_4, _NL_ABALTMON_5, _NL_ABALTMON_6, _NL_ABALTMON_7, _NL_ABALTMON_8, _NL_ABALTMON_9, _NL_ABALTMON_10, _NL_ABALTMON_11, _NL_ABALTMON_12, _NL_WABALTMON_1, _NL_WABALTMON_2, _NL_WABALTMON_3, _NL_WABALTMON_4, _NL_WABALTMON_5, _NL_WABALTMON_6, _NL_WABALTMON_7, _NL_WABALTMON_8, _NL_WABALTMON_9, _NL_WABALTMON_10, _NL_WABALTMON_11, _NL_WABALTMON_12): New enum constants. * locale/programs/ld-time.c (struct locale_time_t): Add ab_alt_mon, wab_alt_mon, and ab_alt_mon_defined members. (time_output): Output ab_alt_mon and wab_alt_mon members. (time_read): Read them, initialize them as copies of abmon and wabmon respectively if they are missing, initialize ab_alt_mon_defined. * locale/programs/locfile-kw.gperf (ab_alt_mon): Define. * locale/programs/locfile-kw.h: Regenerate. * locale/programs/locfile-token.h (tok_ab_alt_mon): New enum constant. * time/Makefile [$(run-built-tests) = yes] (LOCALES): Add es_ES.UTF-8 and ru_RU.UTF-8. * time/strftime_l.c (a_altmonth, aam_len): New macros. [!COMPILE_WIDE] (ABALTMON_1): New macro. (__strftime_internal): Handle %Ob and %Oh formats. * time/strptime_l.c [_LIBC] (ab_alt_month_name): New macro. (__strptime_internal): Handle %Ob and %Oh formats. * time/tst-strptime.c (day_tests): Add more tests to parse different forms of month names including the new %Ob format specifier.
