Later on in that discussion, I did mention that the svn_ctype macros are
a public API. Exporting just svn_xml_is_xml_name_valid doesn't help,
because the macros will still break when used outside libsvn_subr. I
don't care if they're not used elsewhere right now, they a) should be,
and b) are a public API which must work.

Therefore, I suggest exporting a new function, svn_ctype_get_table()
which returns the svn_ctype_table, deprecating the public status of the
latter, and reimplementing the macros with the new function.

(You can give that funtion __attribute__((pure, const)) to give gcc more
opportunity for optimisation.)
