An attempt to import the latest version of hyph-utf8 (#558)

LuaTeX:
* add support for loading multiple pattern files in LuaTeX

TeX Live:
* remove copthyph.tex from texmf: it is now part of hyph-utf8
* update language.ptx and language.def for pTeX
* update some descriptions in tlpsrc files (not finished)
* change lefthyphenmin from 2 to 1 for Afrikaans (not sure when it was set to 2)

hyph-utf8:
* load patterns for Latin and Cyrillic scripts for Serbian simultaneously
* new version of German hyphenation patterns
* support both U+0027 and U+2019 as apostrophe in Unicode engines
