- Removed legacy limitation of worker's types;
  - Using GQuarks to identify workers and modules;
  - Remove modules.sh script;
  - Add a common system of workers and modules;
  - Write management and configuration for new architecture.

Fix lua redis library.

* Fix build of rspamd with CMAKE_BINARY_DIR differs from CMAKE_SOURCE_DIR
Rework include style.

Fix problems found by static analyzing.

Add more debugging to destructors in pools.

Write domain name for redirectors call

 - now symbols inside metrics definition must be inside rules as well
 - symbols may be virtual (e.g. when module can insert several symbols inside callback)
 - symbols may be pure callbacks (when symbol's name is unknown and depends on conditions)
* Module 'emails' is removed as it is not used in the current rspamd
MANY fixes to sample config files

Implement checking for classifier options
Fix redirector to handle timeouts and invalid replies properly
Fix surbl module not to check each url

Improve time limits handling
Fix smtp proxy options parsing

Allow only ASCII symbols in logs, escape control chars

Strictly follow c99 standart.
Turn on pedantic c99 checks.

Now all comments in commit logs beginning with '*' would be included in changelog, so
important changes would be separated from small ones.

* Add support of regexp to check only specific urls for each domains
* Check redirector in trie and not extract specific domains parts
* Add POE errors handling for redirector

* Fix ip address parsing in redirector config
* Fix logic of checking url in redirector if its domain is in exceptions list
* Add dependencies in perl module (suggested by AZ)
* Add BUILD_PORT define for skipping installation of FreeBSD rc scrips (suggested by AZ)
* Change version of 0.3.3

* Fixes to url extracter
* Check urls in redirector even if they are listed in surbl whitelist

* Fix surbl request formatting for ip addresses

* Several fixes to DNS logic

* Write real time of message's scan to log (not only virtual)

* Do not show duplicate urls in url header

* Fix microseconds<->milliseconds conversions

* Fix destroying smtp session (unmap memory and do not delete pool early)

* 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 debug from SURBL module

 - 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.

* 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 minimum hash length to check with fuzzy module as well as whitelisting for fuzzy checks:
  min_length = "300"; <- messages with more than 300 characters would be checked with fuzzy check
  whitelist = "http://somehost/somefile"; <- ip addresses whitelisted
* Extend comments about module options for comfortable usage

  - 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

* Add skeleton for spf parser
