lib-fts: Add prefixing contraction filter. Filters away prefixing contracted words, e.g. "l'homme" -> "homme". Tokens to be filtered must be lower case. Only supports French in this initial version.

lib-fts: Added "english-possessive" filter.

lib-fts: fts-filter API changed to have a non-pointer vfuncs variable. The main benefit being that the fts-filter implementations can save a few lines of code.

lib-fts: Implemented default create/destory functions for fts-filters.

lib-fts: Compiling fix without libicu

lib-fts: Do all the ICU cleanup in fts_icu_deinit().

lib-fts: Include fts-filter.h in fts-filter-private.h This avoids having to always include them both.

lib-fts: Call libicu u_cleanup.

lib-fts: Added assert to fts_filter_filter() to make sure input token isn't empty

lib-fts: Added asserts to make sure we don't return empty tokens.

lib-fts: Minor code cleanups

lib-fts: Store pointers to fts_filter classes instead of copying the data. Doesn't really matter, but it's a bit cleaner when fts_filter_find() returns the same pointer as the fts_filter class originally was.

lib-fts: Added "lowercase" filter. For now it handles only ASCII characters, but that's enough for our use.

lib-fts: Removed "simple" normalizer. It translated input to titlecase, which wasn't suitable for snowball stemming that wanted lowercase input. Since that doesn't work, there's probably no good for the existence of this (perhaps in future it's replaced by unicode-aware lowercaser).

lib-fts: Fixed test-fts-filter unit test to handle errors a bit better.

lib-fts: Changed filter's internal APIs to return error_r directly. It's not very safe to store strings allocated from data stack to any permanent structs.

fts: Improve filter error handling. In lib-fts: Move error storage to the generic filter struct level. Change make_utf8 helper to void also. In fts: Add the error argument to _filter() calls.

fts: Change filter API to be able to return errors Modify fts_filter_filter() to return integer status codes. It returns 1 if a token was returned, 0 if it was filtered away and -1 on error.

lib-fts: Added normalizer-simple for doing normalization without libicu.

lib-fts: Renamed normalizer to icu-normalizer, including the source code.

Initial import for lib-fts. Parts of what this code does was already implemented internally by fts-lucene. lib-fts is intended to be usable for all the FTS backends. The APIs are still going to change a bit, but hopefully not after v2.2.17 release. Mostly written by Teemu Huovila.
