Implements the following behind an experimental configuration flag:
* A new push rule kind for mutually related events.
* A new default push rule (`.m.rule.thread_reply`) under an unstable prefix.
This is missing part of MSC3772:
* The `.m.rule.thread_reply_to_me` push rule, this depends on MSC3664 / #11804.
* Move `_condition_checker` into `PushRuleEvaluatorForEvent`.
* Move the condition cache into `PushRuleEvaluatorForEvent`.
* Improve docstrings.
* Inline a method which is only called once.
* Fix `PushRuleEvaluator` to work on frozendicts
frozendicts do not (necessarily) inherit from dict, so this needs to handle
them correctly.
* Fix event filtering for frozen events
Looks like this one was introduced by #11194.
* tests for push rule pattern matching
* tests for acl pattern matching
* factor out common `re.escape`
* Factor out common re.compile
* Factor out common anchoring code
* add word_boundary support to `glob_to_regex`
* Use `glob_to_regex` in push rule evaluator
NB that this drops support for character classes. I don't think anyone ever
used them.
* Improve efficiency of globs with multiple wildcards
The idea here is that we compress multiple `*` globs into a single `.*`. We
also need to consider `?`, since `*?*` is as hard to implement efficiently as
`**`.
* add assertion on regex pattern
* Fix mypy
* Simplify glob_to_regex
* Inline the glob_to_regex helper function

Part of #9744
Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now.

* Fix spec compliance; tweaks without values are valid
(default to True, which is only concretely specified for
`highlight`, but it seems only reasonable to generalise)
* Changelog for 7766.
* Add documentation to `tweaks_for_actions`
May as well tidy up when I'm here.
* Add a test for `tweaks_for_actions`
Only prepend / append word bounary characters if the search
expression starts or ends with a word character, otherwise they
don't work because there's no word bounary between whitespace and
a non-word char.
Initialising `result` to `{}` in the parameters meant that every call to
_flatten_dict used the *same* target dictionary.
I'm hopeful this will fix https://github.com/matrix-org/synapse/issues/2270,
but I suspect it won't. (This code seems to have been here since forever,
unlike the bug, and I don't really think it explains the observed
behaviour). Still, it makes it hard to investigate the problem.
It wasn't possible to hit the code from the API because of a typo
in parsing the request path. Since no-one was using the feature
we might as well remove the dead code.
