Subject: fdo#80403: TokenHandler impl. FastTokenHandlerBase

getTokenFromUTF8: calls getTokenDirect
getTokenDirect: uses perfect hash

New makefile creates perfect hash table with perl-script gentoken.pl.
I found the script on https://wiki.openoffice.org/wiki/XFastTokenHandler and made some changes.
XMLTokens are defined in tokens.txt
