Simplification to Keyring.wait_for_previous_lookups. (#5250)
The list of server names was redundant, since it was equivalent to the keys on
the server_to_deferred map. This reduces the number of large lists being passed
around, and has the benefit of deduplicating the entries in `wait_on`.

895b79ac2e Factor out KeyFetchers from KeyRing
Rather than have three methods which have to have the same interface,
factor out a separate interface which is provided by three implementations.

I find it easier to grok the code this way.

b75537beaf Store key validity time in the storage layer
This is a first step to checking that the key is valid at the required moment.

The idea here is that, rather than passing VerifyKey objects in and out of the
storage layer, we instead pass FetchKeyResult objects, which simply wrap the
VerifyKey and add a valid_until_ts field.

Simplify process_v2_response (#5236)
* Pass time_added_ms into process_v2_response

* Simplify process_v2_response

We can merge old_verify_keys into verify_keys, and reduce the number of dicts
flying around.

Remove unused VerifyKey.expired and .time_added fields (#5235)
These were never used, and poking arbitary data into objects from other
packages seems confusing at best.

Rewrite store_server_verify_key to store several keys at once (#5234)
Storing server keys hammered the database a bit. This replaces the
implementation which stored a single key, with one which can do many updates at
once.

f88a9e6323 Remove redundant merged_keys dict
There's no point in collecting a merged dict of keys: it is sufficient to
consider just the new keys which have been fetched by the most recent
key_fetch_fns.

7d2a0c848e Fix from_server buglet in get_keys_from_perspectives
make sure we store the name of the server the keys came from, rather than the
origin server, after doing a fetch-from-perspectives.

6ae9361510 Hoist server_name check out of process_v2_response
It's easier to check it in the caller than to complicate the interface with an
extra param.

ef27d434d1 Clean up Keyring.process_v2_response
Make this just return the key dict, rather than a single-entry dict mapping the
server name to the key dict. It's easy for the caller to get the server name
from from the response object anyway.

855a151015 Refactor event signing to work on dicts
This is in preparation for making EventBuilder format agnostic, which

the EventBuilder object.

Don't send IP addresses as SNI (#4452)
The problem here is that we have cut-and-pasted an impl from Twisted, and then
failed to maintain it. It was fixed in Twisted in
https://github.com/twisted/twisted/pull/1047/files; let's do the same here.

ef771cc4c2 Fix a number of flake8 errors
Broadly three things here:

* disable W504 which seems a bit whacko
* remove a bunch of `as e` expressions from exception handlers that don't use
  them
* use `r""` for strings which include backslashes

Also, we don't use pep8 any more, so we can get rid of the duplicate config
there.

808d8e06aa Don't log exceptions when failing to fetch server keys
Not being able to resolve or connect to remote servers is an expected
error, so we shouldn't log at ERROR with stacktraces.

e82db24a0e Try to log more helpful info when a sig verification fails
Firstly, don't swallow the reason for the failure

Secondly, don't assume all exceptions are verification failures

Thirdly, log a bit of info about the key being used if debug is enabled

2a13af23bc Use run_in_background in preference to preserve_fn
While I was going through uses of preserve_fn for other PRs, I converted places
which only use the wrapped function once to use run_in_background, to avoid
creating the function object.
