unicode: implement higher level API for string handling
This patch integrates the utf8n patches with some higher level API to perform UTF-8 string comparison, normalization and casefolding operations. Implemented is a variation of NFD, and casefold is performed by doing full casefold on top of NFD. These algorithms are based on the core implemented by Olaf Weber from SGI.
