* New rspamd protocol (changed replies)

* Add ability to attach string lists to symbols
* Check destructors and do not add identical destructors (argument and function) to pool's destructors
* Remove 2 warnings when building with gmime22
* Attach url names to surbl symbols
* Fix bug with blocking on read (I think it is linux specific thought)
