Update charset source from latest definitions

Update charset definitions based on newest ones from Unicode mirror and
O'Reilly FTP site, using modified dump.c as well as some additional
charmaps reverse engineered from existing cjk.c. The extra files
can be retrieved from

https://github.com/abelcheung/misc/tree/master/fontforge-20140101-charmaps

Mac Symbol, Zapf Dingbats, ISO-8859-{6,7,10,13} have major update, while
some have minor updates as well. All single byte charsets have C0/C1
control chars as originally specified in mapping file.

This update shall act as a reference result for the upcoming unicode
generation tool rewrite.
