configure: Fixed/improved finding and using libexttextcat. libexttextcat wasn't actually being used at all by fts-lucene. Now we'll first prefer finding it via pkg-config, next finding exttextcat and only last look up textcat.

configure: Stemmer and textcat checks are now done even if CLucene isn't used. They'll be useful for other FTS backends as well. This patch doesn't change any actual functionality.

configure: Use pkg-config with clucene if available.

Debian names libtextcat as libexttextcat. Patch by Stephan Bosch.

fts-lucene: Fixed Makefile.am

fts-lucene: Added default_language setting and separated stemmer/textcat support.

fts-lucene: Added "doveadm dump" support for lucene index.

Makefile fixes to include everything in dist

fts-lucene: Fixed compiling without textcat/snowball

fts-lucene: Added initial support for language detection and stemming. This requires textcat and snowball (libstemmer) libraries. This can be enabled by setting: fts_lucene = textcat_dir=/usr/share/libtextcat \ textcat_conf=/etc/dovecot/textcat.conf I'm not yet sure how good of an idea it is to actually use this, so it needs some testing.. For example how bad is it if language is detected incorrectly?

fts-lucene: Fixes to work with CLucene v2.3.3.4 and new FTS API. It's still not recommended to actually use this.

Use -Wl,--as-needed -Wl,--no-undefined GNU ld flags for non-plugins.

Get rid of imap/, pop3/, lda/ and sql/ module subdirs. It's all in lib/dovecot/ now. --HG-- branch : HEAD

Symlink FTS plugins to pop3 directory too. --HG-- branch : HEAD

Previous changes broke plugin symlink creation in make install. --HG-- branch : HEAD

Use dynamic module suffix provided by libtool rather than hardcoded ".so". --HG-- branch : HEAD

Add lucene-wrapper.h to distribution. --HG-- branch : HEAD

Better type safety to module_contexts arrays. Already fixed some bugs. --HG-- branch : HEAD

Changed the plugin filename numbering (ie. the ordering in which the plugins are loaded). This doesn't change anything for current plugins, but future plugins will need this change so they can get themselves loaded between specific plugins. --HG-- branch : HEAD

--with-lucene now enables lucene full text search indexing. Note that using it breaks IMAP RFC. It also seems to have problems finding texts that have special characters in them, such as email addresses. You can anyway enable it by loading fts and fts_lucene plugins and setting fts=lucene in plugin section. --HG-- branch : HEAD
