Only lazy load self-members on initial sync 
Given we have disabled lazy loading for incr syncs in #3840, we can make self-LL more efficient by only doing it on initial sync.  Also adds a bounds check for if/when we change our mind, so that we don't try to include LL members on sync responses with no timeline.

703de4ec13 Comments and interface cleanup for on_receive_pdu 
Add some informative comments about what's going on here.

Also, `sent_to_us_directly` and `get_missing` were doing the same thing (apart
from in `_handle_queued_pdus`, which looks like a bug), so let's get rid of
`get_missing` and use `sent_to_us_directly` consistently.

Improve the logging when handling a federation transaction (#3904) 
Let's try to rationalise the logging that happens when we are processing an
incoming transaction, to make it easier to figure out what is going wrong when
they take ages. In particular:

- make everything start with a [room_id event_id] prefix
- make sure we log a warning when catching exceptions rather than just turning
  them into other, more cryptic, exceptions.

7baf66ef5d Send existing room tags down sync on join 
When a user joined a room any existing tags were not sent down the sync
stream. Ordinarily this isn't a problem because the user needs to be in
the room to have set tags in it, however synapse will sometimes add tags
for a user to a room, e.g. for server notices, which need to come down
sync.

91cdb6de08 Call UserDirectoryHandler methods directly 
Turns out that the user directory handling is fairly racey as a bunch
of stuff assumes that the processing happens on master, which it doesn't
when there is a synapse.app.user_dir worker. So lets just call the
function directly until we actually get round to fixing it, since it
doesn't make the situation any worse.

the "Starting db txn 'get_all_updated_receipts' from sentinel context" warning.

Instead, give them their own "background process" logcontexts.

360ba89c50 Don't fail requests to unbind 3pids for non supporting ID servers 
Older identity servers may not support the unbind 3pid request, so we
shouldn't fail the requests if we received one of 400/404/501. The
request still fails if we receive e.g. 500 responses, allowing clients
to retry requests on transient identity server errors that otherwise do
support the API.

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.

01e93f48ed Kill off MatrixCodeMessageException 
This code brings the SimpleHttpClient into line with the
MatrixFederationHttpClient by having it raise HttpResponseExceptions when a
request fails (rather than trying to parse for matrix errors and maybe raising
MatrixCodeMessageException).

Then, whenever we were checking for MatrixCodeMessageException and turning them
into SynapseErrors, we now need to check for HttpResponseExceptions and call
to_synapse_error.

Deduplicate redundant lazy-loaded members (#3331) 
* attempt at deduplicating lazy-loaded members

as per the proposal; we can deduplicate redundant lazy-loaded members
which are sent in the same sync sequence. we do this heuristically
rather than requiring the client to somehow tell us which members it
has chosen to cache, by instead caching the last N members sent to
a client, and not sending them again.  For now we hardcode N to 100.
Each cache for a given (user,device) tuple is in turn cached for up to
X minutes (to avoid the caches building up).  For now we hardcode X to 30.

* add include_redundant_members filter option & make it work

* remove stale todo

* add tests for _get_some_state_from_cache

* incorporate review

03751a6420 Fix some looping_call calls which were broken in #3604 
It turns out that looping_call does check the deferred returned by its
callback, and (at least in the case of client_ips), we were relying on this,
and I broke it in #3604.

Update run_as_background_process to return the deferred, and make sure we
return it to clock.looping_call.

8b8c4f34a3 Replace usage of get_current_toke with StreamToken.START 
This allows us to handle /context/ requests on the client_reader worker
without having to pull in all the various stream handlers (e.g.
precence, typing, pushers etc). The only thing the token gets used for
is pagination, and that ignores everything but the room portion of the
token.

fed62e21ad Infrastructure for a server notices room 
Server Notices use a special room which the user can't dismiss. They are
created on demand when some other bit of the code calls send_notice.

(This doesn't actually do much yet becuse we don't call send_notice anywhere)

e2accd7f1d Refactor sync APIs to reuse pagination API 
The sync API often returns events in a topological rather than stream
ordering, e.g. when the user joined the room or on initial sync. When
this happens we can reuse existing pagination storage functions.

bf98fa0864 Part user from rooms on account deactivate 
This implements this very crudely: this probably isn't viable
because parting a user from all their rooms could take a long time,
and if the HS gets restarted in that time the process will be
aborted.

6493b22b42 reraise exceptions more carefully 
We need to be careful (under python 2, at least) that when we reraise an
exception after doing some error handling, we actually reraise the original
exception rather than anything that might have been raised (and handled) during
the error handling.

605defb9e4 Add missing consumeErrors

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.
