    Fixes for thai linebreaking

    * Load libthai.so.0 since libthai.so is not there on all systems
    * Remove dependency on codecs. Unicode->TIS620 is so simple we can
    simply hardcode it in harbuzz-thai.c
    * Speed up detection of word boundaries
    * Falback when libthai is not found is now to not break instead of
    breaking after every character (in line with recommendations from
    unicode.org linebreaking algorithm)
