	* doc/unicode/unicode-blocks.pl: Minor updates, to avoid warnings.
	* doc/unicode/unicode-muncher.pl: Rewrite, to incorporate ideas
	from Artur Biesiadowski: use a 2-level lookup of fixed-length
	blocks instead of a 1-level lookup of variable-length blocks, and
	store the data in String literals in a Java interface instead of
	in binary files.
	* doc/unicode/unicode.database.format: Remove, as
	gnu/java/lang/CharData is self-documenting.
	* gnu/java/locale/block.uni: Remove, replaced by
	gnu/java/lang/CharData.java.
	* gnu/java/locale/character.uni: Ditto.
	* gnu/java/locale/titlecase.uni: Ditto.
	* gnu/java/lang/Makefile.am (EXTRA_DIST): Add CharData.java.
	* gnu/java/lang/CharData.java: New file, holding the Unicode
	database for java.lang.Character.
	* java/lang/Character.java (blocks, data, numValue, upper, lower),
	(direction, title): Replace blocks, tcs, and unicodeData as the
	Unicode database used in all other methods; initialized by
	gnu.java.lang.CharData.
	(<clinit>, getBlock, class Block, class CharAttr): Delete;
	character attribute lookup now uses char[] instead of objects.
	(readChar): Update to use new database.
	(Various others): Reduce multiple comparisons to just one when
	checking a character's type.
