Richard van der Hoff 0a65450d04 Validation for events/rooms in fed requests
When we get a federation request which refers to an event id, make sure that
said event is in the room the caller claims it is in.

Richard van der Hoff 018d75a148 Refactor code for turning HttpResponseException into SynapseError
This commit replaces SynapseError.from_http_response_exception with
HttpResponseException.to_synapse_error.

The new method actually returns a ProxiedRequestError, which allows us to pass
through additional metadata from the API call.

Richard van der Hoff 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.

Richard van der Hoff c82ccd3027 Factor out exception handling in federation_client
Factor out the error handling from make_membership_event, send_join, and
send_leave, so that it can be shared.

Travis Ralston e908b86832 Remove pdu_failures from transactions
The field is never read from, and all the opportunities given to populate it are not utilized. It should be very safe to remove this.

Richard van der Hoff 667fba68f3 Run things as background processes
This fixes #3518, and ensures that we get useful logs and metrics for lots of
things that happen in the background.

(There are certainly more things that happen in the background; these are just
the common ones I've found running a single-process synapse locally).

Richard van der Hoff 6e3fc657b4 Resource tracking for background processes
This introduces a mechanism for tracking resource usage by background
processes, along with an example of how it will be used.

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.

Krombel 3366b9c534 rename assert_params_in_request to assert_params_in_dict

Richard van der Hoff 546bc9e28b More server_name validation
We need to do a bit more validation when we get a server name, but don't want
to be re-doing it all over the shop, so factor out a separate
parse_and_validate_server_name, and do the extra validation.

Also, use it to verify the server name in the config file.

Reject invalid server names (#3480)
Make sure that server_names used in auth headers are sane, and reject them with
a sensible error code, before they disappear off into the depths of the system.

Richard van der Hoff 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.

Richard van der Hoff 9255a6cb17 Improve exception handling for background processes
There were a bunch of places where we fire off a process to happen in the
background, but don't have any exception handling on it - instead relying on
the unhandled error being logged when the relevent deferred gets
garbage-collected.

This is unsatisfactory for a number of reasons:
 - logging on garbage collection is best-effort and may happen some time after
   the error, if at all
 - it can be hard to figure out where the error actually happened.
 - it is logged as a scary CRITICAL error which (a) I always forget to grep for
   and (b) it's not really CRITICAL if a background process we don't care about
   fails.

So this is an attempt to add exception handling to everything we fire off into
the background.
