8e3d34e3c5 Use event origin for filtering incoming events
We only process events sent to us from a server if the event ID matches
the server, to help guard against federation storms. We replace this
with a check against the event origin.

55d9024835 Use snder and not event ID domain to check if ours
The transaction queue only sends out events that we generate. This was
done by checking domain of event ID, but that can no longer be used.
Instead, we may as well use the sender field.

6598992b01 Fixup calls to comput_event_signature
We currently pass FrozenEvent instead of `dict` to
`compute_event_signature`, which works by accident due to `dict(event)`
producing the correct result.

This fixes PR #4493 commit 855a151

886e5acc76 Store rejected remote invite events as outliers
Currently they're stored as non-outliers even though the server isn't in
the room, which can be problematic in places where the code assumes it
has the state for all non outlier events.

In particular, there is an edge case where persisting the leave event
triggers a state resolution, which requires looking up the room version
from state. Since the server doesn't have the state, this causes an
exception to be thrown.

82e13662c0 Split federation OpenID userinfo endpoint out of the federation resource
This allows the OpenID userinfo endpoint to be active even if the
federation resource is not active. The OpenID userinfo endpoint
is called by integration managers to verify user actions using the
client API OpenID access token. Without this verification, the
integration manager cannot know that the access token is valid.

The OpenID userinfo endpoint will be loaded in the case that either
"federation" or "openid" resource is defined. The new "openid"
resource is defaulted to active in default configuration.

b970cb0e96 Refactor request sending to have better excpetions (#4358)
* Correctly retry and back off if we get a HTTPerror response

* Refactor request sending to have better excpetions

MatrixFederationHttpClient blindly reraised exceptions to the caller
without differentiating "expected" failures (e.g. connection timeouts
etc) versus more severe problems (e.g. programming errors).

This commit adds a RequestSendFailed exception that is raised when
"expected" failures happen, allowing the TransactionQueue to log them as
warnings while allowing us to log other exceptions as actual exceptions.

* 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.

fc0f13dd03 Fix incorrect truncation in get_missing_events
It's quite important that get_missing_events returns the *latest* events in the
room; however we were pulling event ids out of the database until we got *at
least* 10, and then taking the *earliest* of the results.

We also shouldn't really be relying on depth, and should be checking the
room_id.

Include eventid in log lines when processing incoming federation transactions (#3959)
when processing incoming transactions, it can be hard to see what's going on,
because we process a bunch of stuff in parallel, and because we may end up
recursively working our way through a chain of three or four events.

This commit creates a way to use logcontexts to add the relevant event ids to
the log lines.

9453c65948 remove spurious federation checks on localhost
There's really no point in checking for destinations called "localhost" because
there is nothing stopping people creating other DNS entries which point to
127.0.0.1. The right fix for this is
https://github.com/matrix-org/synapse/issues/3953.

Blocking localhost, on the other hand, means that you get a surprise when
trying to connect a test server on localhost to an existing server (with a
'normal' server_name).

89a76d1889 Fix handling of redacted events from federation
If we receive an event that doesn't pass their content hash check (e.g.
due to already being redacted) then we hit a bug which causes an
exception to be raised, which then promplty stops the event (and
request) from being processed.

This effects all sorts of federation APIs, including joining rooms with
a redacted state event.

fa7dc889f1 Be more careful which errors we send back over the C-S API
We really shouldn't be sending all CodeMessageExceptions back over the C-S API;
it will include things like 401s which we shouldn't proxy.

That means that we need to explicitly turn a few HttpResponseExceptions into
SynapseErrors in the federation layer.

The effect of the latter is that the matrix errcode will get passed through
correctly to calling clients, which might help with some of the random
M_UNKNOWN errors when trying to join rooms.

This introduces a mechanism for tracking resource usage by background

This will help address #3518, but more importantly will give us better insights
into things which are happening but not being shown up by the request metrics.

We *could* do this with Measure blocks, but:
 - I think having them pulled out as a completely separate metric class will
   make it easier to distinguish top-level processes from those which are
   nested.

 - I want to be able to report on in-flight background processes, and I don't
   think we want to do this for *all* Measure blocks.
