So, it turns out that if you have a first `Deferred` `D1`, you can add a
callback which returns another `Deferred` `D2`, and `D2` must then complete
before any further callbacks on `D1` will execute (and later callbacks on `D1`
get the *result* of `D2` rather than `D2` itself).
So, `D1` might have `called=True` (as in, it has started running its
callbacks), but any new callbacks added to `D1` won't get run until `D2`
completes - so if you `yield D1` in an `inlineCallbacks` function, your `yield`
will 'block'.
In conclusion: some of our assumptions in `logcontext` were invalid. We need to
make sure that we don't optimise out the logcontext juggling when this
situation happens. Fortunately, it is easy to detect by checking `D1.paused`.
In most cases, we limit the number of prev_events for a given event to 10
events. This fixes a particular code path which created events with huge
numbers of prev_events.
This is a mixed commit that fixes various small issues
* print parentheses
* 01 is invalid syntax (it was octal in py2)
* [x for i in 1, 2] is invalid syntax
* six moves

These worked accidentally before (python2 doesn't complain if you
compare incompatible types) but under py3 this blows up spectacularly

Doing this I learned e.message was pretty shortlived, added in 2.6,
they realized it was a bad idea and deprecated it in 2.7

Currently the handling of auto_join_rooms only works when a user
registers itself via public register api. Registrations via
registration_shared_secret and ModuleApi do not work
This auto_joins the users in the registration handler which enables
the auto join feature for all 3 registration paths.
This is related to issue #2725

* Split state group persist into seperate storage func
* Add per database engine code for state group id gen
* Move store_state_group to StateReadStore
This allows other workers to use it, and so resolve state.
* Hook up store_state_group
* Fix tests
* Rename _store_mult_state_groups_txn
* Rename StateGroupReadStore
* Remove redundant _have_persisted_state_group_txn
* Update comments
* Comment compute_event_context
* Set start val for state_group_id_seq
... otherwise we try to recreate old state groups
* Update comments
* Don't store state for outliers
* Update comment
* Update docstring as state groups are ints
We extract the storage-independent bits of the state group resolution out to a
separate functiom, and stick it in a new handler, in preparation for its use
from the storage layer.
... instead of creating our own special SQLiteMemoryDbPool, whose purpose was a
bit of a mystery.
For some reason this makes one of the tests run slightly slower, so bump the
sleep(). Sorry.
