  All the previous changes (except the backward compatibility) 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 feature
the declension suffixes.

	[BZ #10871]
	* locale/C-time.c: Add abbreviated alternative month names, define
	them as the same as abbreviated month names explicitly.
	* locale/categories.def: ab_alt_mon and wide-ab_alt_mon added.
	* locale/langinfo.h: _NL_[W]ABALTMON_1 .. _NL_[W]ABALTMON_12
	defined.
	* locale/programs/ld-time.c: Abbreviated alternative month names
	support added, they are a copy of abmon if not provided
	explicitly.
	* locale/programs/locfile-kw.gperf: ab_alt_mon defined.
	* locale/programs/locfile-token.h: tok_ab_alt_mon defined.
	* time/strftime_l.c: %Ob (%Oh) format for abbreviated
	alternative month names added.
	* time/strptime_l.c: Abbreviated alternative month names also
	recognized.

Again, I'm reviewing this on the assumption that the feature has
consensus, and I'm asking Joseph to check for conformance problems.

Same concerns re the ChangeLog as I expressed for the earlier patch.

This appears to make the order-of-checks inconsistency, that I
remarked on in the previous patch, even worse.  Please make sure the
checks are done in a consistent order in both places.

Otherwise looks good to me.
