* Fix issue with links that are ip addresses in numeric form in surbl
* On Darwin use BSD style sendfile definition
* Reorganize platform specific knobs in CMakeLists
* Use gettimeofday on systems that have not clock_getres
* Use ftime for dns trans id generation on systems without clock_getres

 - remove completely 2tld
 - add option "exception"
 - for domains from exception list check (level + 1) parts of url:
   If we have url mail.some.com.ru and have com.ru in exception list
   then we would check some.com.ru. If we have some.com.ru in exceptions
   list them mail.some.com.ru would be checked and so on.
 - optimized parsing of surbl requests

* Use system mkstemp(3) on systems where it is available as glib implementation
  has poor security and generate rather predictable temporary file names.

* Fix issues with smtp worker

* Completely remove lex/yacc readers for config
* Make common sense of metric/action and symbols
* Sync changes with all plugins
TODO: add this to documentation

* Add support for sendfile in io dispatcher
* Fix issues with compatibility of worker_task and smtp proxy
* Proxy DATA command

  - delay
  - helo
  - mail from
  - rcpt
* Implement interaction with smtp upstream (with support of XCLIENT)

* Fix tanhl detection for platforms that have not implementation of it
* Remove several compile warnings

  - add ability to have dynamic rules inside items cache
  - make 3 types of rules: negative, dynamic and static
  - make logic of cache more simple by using glib lists instead of arrays
  - do checks of symbols in more logically correct way (negative->dynamic->static)

* Use hyperbolic tangent for internal normalizer

* Fix minor errors in logging initializing
* Fix installation of config files

* Add missing sections to XML parser (classifier, statfile, view, settings)
* Add missing params to XML parser
* Implement new commandline options parser (using glib)
* Set version to 0.3.0 as new rspamd would use new config system

* Fix building and installing perl target
* Fix learn command name
* Controller's commands are now case insensitive
* Statfiles can now be selected from popup list in cgi interface
* Password for controller's commands can now be specified in cgi interface

  things TODO:
  - improve interaction with rspamc
  - improve documentation
  - test all features
  - test clustering
  - write CGI front-end

* Add support for spf 2.0 (Sender ID policy)
* Add support of MAP_NOCORE to systems that supports it (FreeBSD for example)

* Some additions to radix tree library:
  - allow tree traverse
  - add new insert methods (add and replace)
  - store keys in radix nodes (thought we can calculate key by bits, but I think that storing key is not too expensive)
  - values in a tree are now uintptr_t

  - custom filters are dlopened and provides callbacks for user's input processing
  - custom filters can be used to extend rspamd functionality for unusual (non email processing cases)
  - custom filters allows to use rspamd async IO model and process management for performing custom network tasks

  - independent and customizeable buffering
  - line buffering
  - errors handling support
  - custom (ip based) debug
  - append function name automaticaly (based on __FUNCTION__)
  - add some logic to logs system

* Fix dependency on lex and yacc sources

  - add plugin to work with spf records (initial version)
  - make all spf types working (except include and redirect that still need some attention)
  - add support of MX records to evdns
  - some major fixes and testing of the whole spf subsystem

* Style fix to perl module

 - remove XS API, it seems that I would never support it
 - use sys(write|read) for IO in Mail::Rspamd::Client
 - add proper installation process for Mail::Rspamd::Client
 - remove some other legacy

--HG--
rename : perl/Client.pm => perl/lib/Mail/Rspamd/Client.pm

* Add skeleton for spf parser

* Fix build WITH_LUA
* Fix calling of classifier
* Fix autolearn

* Some tunes to lua API
* Fix bug with http maps
* Optimize installation and make custom prefix for configs

* Make logging adaptive based on log speed (buffered vs unbuffered IO)
* Fix lua API docs
* Now lua modules can be loaded with glob patterns

* Pass to event_add only copies of struct timeval to avoid timing problems
