Add Java 6's getAvailableLocales/getInstance to DateFormatSymbols and DecimalFormatSymbols.

This patch also improves the documentation of all getAvailableLocales methods
to clarify exactly what "available" means. Note that at the moment, many of
our implementations just return Locale.getAvailableLocales. It turns out that
ICU does the same in most cases, but I'll come back in a separate patch and
add code so we just pass these down to ICU, and wash our hands of the matter.

I've rewritten DateFormatSymbols.equals, which was very wrong. The time zone
names comparison had an invalid optimization, and its slow-path loop was wrong
too: it only ever tested values against themselves, which isn't likely to have
been the author's intention.

I've added toString overrides to DateFormatSymbols and DecimalFormatSymbols,
because I need them every time I work on these classes.

I've made the constants in DecimalFormatSymbols static final, and given them
idiomatic names. (I still think we might benefit from breaking these into
separate fields, as in the serialized form, but that's a separate issue.)

Finally, and unrelatedly, I've added a comment to BreakIteratorProvider that
I missed in my last change to that file.
