* New fuzzy check logic:
- use shingles algorithm for fuzzy matching
- use blake2 instead of md5 for larger output space
- combine fuzzy and strict matching
- allow to organize private storages by means of keys
- preserve compatibility with previous versions
* New fuzzy storage:
- use sqlite instead of own memory based hash tables
- rework commands interface
- add conversion from the old format
- add fuzzy match by shignles
- support old rspamd versions
* Add lemmatizing for words used in fuzzy hashes that allows to improve match
quality by using of the first forms of all words
* Rework language detection
* Fix several critical bugs, memory leaks and deadlocks:
- memory leak in HTML nodes parsing
- deadlock in logger code
- deadlock in signals processing
- crashes in fuzzy_storage
- crashes in tokenizers if the input was empty
* Import new libucl with several bugfixes and improvements
* Support listening on ipv6 addresses only
* Fix macro expansion in SPF module
* Several bugfixes in DKIM module
* Add load headers support for mime parts to the lua API
* Add documentation for:
- workers in general
- fuzzy_storage worker
- fuzzy_check plugin
- mimepart and textpart lua API modules

* 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

* Set sockaddr.sa_family properly when connectig to upstreams
* Fix reload issues in surbl and fuzzy_check (reported by @citrin)
* Fix timeouts in redirector
* Improve lua errors reporting
* Fix lua closures processing in libucl
* Rework calling of lua functions from regexp module
* Choose raw regexp for raw headers
* Rework conversion to utf since glib one is broken
* Ignore SGML style tags in html
* Fix old bug with non-capturing https urls
* Fix memory corruption on fuzzy reload (reported by @citrin)
* Fix percents display in rspamc
* Fix buffer update for DKIM
* Do not validate utf for raw headers

* 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 upstreams interaction for fuzzy_check
* Verify spf PTR records (reported by @citrin)
* Fix spf MX records parsing
* Add compatibility for old libevent (by @yellowman)
* Sync bugfixes from libucl

* 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

- Remove sendfile since it was broken
- Fix rspamd spam report for exim
* Improve documentation

There is no significant advantage to use Judy arrays over glib
HashTables to store hashes in fuzzy storage. Therefore, drop support of
Judy completely. Also rename `use_judy` parameter to `strict_hash`
indicating that hashes are matched strictly (not a fuzzy match but a hash
lookup).
