* Apply boundary fix for dkim simple canonization
* Fix ping command
* Return nil if header was not found in lua_task
* Fix hang in upstreams revive logic
* Decode entitles when normalizing HTML parts
* Fix logic of finding URLs in HTML parts
* Do not include \0 into length of text when performing conversion to utf8
* Fix raw vs parsed reperesentations
	Raw parts are now:
		- decoded b64/qp, but *NOT* converted to utf-8
	Processed parts are now:
		- converted to UTF-8
		- normalized if needed (e.g. HTML tags are stripped)
* Rework DKIM canonization to line based
* Fix fuzzy hashes addding
* Use more specific hash function for fuzzy
* Fix leaking of iconv descriptors
* Fix PTR resolving in lua resolver
* Rework spf module.
	- Copy data to memory pool as cached record might be destroyed causing
	    freed memory being passed to the protocol output (use after free)
	- Allow SPF_NEUTRAL policy to be handled separately
	- Add R_SPF_NEUTRAL to the default config
* Rework `register_symbols` function
* Allow to disable components of hfilter

* New upstreams code:
	- simplify upstreams API;
	- unify strings parsing in upstreams definition;
	- add configuration options for the upstreams;
	- for failed upstreams re-resolve their addresses;
	- use all resolved addresses for an upstream (round-robin);
	- implement stable hashing and use it by default for upstreams;
	- add unit test for upstreams module.
* Rework signals processing in all rspamd workers:
	- signals are now processed in the event loop;
	- implement the most common signal handlers for all workers;
	- add callbacks for workers specific signal handlers
*  Fix critical issue with fuzzy storage:
	Fuzzy stroage could not save any hashes on termination due to bugged
	signals handling
* Fix roll history IP storage
* Rework ipv4/ipv6 handling in parsing addresses:
	    - turn off support of IPV6_V6ONLY socket option;
	    - create ipv6 socket prior to ipv4 one to handle systems with v6/v4
	    sockets enabled (Linux)
* Remove CBL as it's wholly included in Spamhaus XBL (by @fatalbanana)
* Remove nszones.com fake RBL (by @citrin)

* Fix typo in stat output.
* Fix issues with includes crossing with the system includes
* Restore testing framework
* Add radix trie test suite
* Implement new path-compressed radix trie.
    - The performance benefit over the old algorithm is about 1.5 times.
        - Memory usage is significantly lower as well.
    - Now radix trie can accept any IPv4/IPv6 values
* Various improvements to the memory pools code
* Fix writing reply to a client when no filters are defined
* Write base32 encoded fuzzy
* Fix 'soft reject' action
* Fix rspamd reload and modules reconfiguration
