Patch: FYI: merge locale data

[Tom Tromey]

I'm checking this in on the trunk.

This "merges" locale data with classpath, by deleting our copy of it.
Now the locale data is stored in .properties files (which are
smaller).  This also changes things to prefer the Classpath copies of
most of the locale-data-using classes (except Collator as we have a
decomposition function that Classpath doesn't yet have).

This change is an overall plus for us as these classes have a number
of bug fixes in Classpath.  Also, the new locale data files are
actually maintainable, as they are created by a documented process
(our old ones were a one-off based on a horribly hacked version of
localeconv).

There will be an issue here for users who statically link as the files
are no longer pulled in by MainThread.
