[cp-patches] Minor refactoring of Character class

[Ivan Maidanski]

Hi!

This is the reformatted log entries for my patch #13 
(http://article.gmane.org/gmane.comp.java.classpath.patches/12965/).

ChangeLog entries:
        * java/lang/Character.java:
        (UnicodeBlock.of(int)): Remove the trailing dot character for
        exception messages.
        (UnicodeBlock.forName(String)): Likewise.
        (charCache): Make the private field final.
        (convertCharData(String[])): New private static function (called
        during the class initialization only).
        (blocks): Call convertCharData() (which creates the appropriate array
        and calls zeroBasedStringValue() for each array element).
        (data): Likewise.
        (numValue): Likewise.
        (upper): Likewise.
        (lower): Likewise.
        (direction): Likewise.
        (readCodePoint(int)): Remove unnecessary "&" operation.
        (reverseBytes(char)): Likewise.
        (isSpace(char)): Simplify the expression.
