* remove dh_params and set better cipher string

Implement server side of MSC1794 - Federation v2 Invite API

Add groundwork for new versions of federation APIs

* Migrate encryption state on room upgrade

Signed-off-by: Andrew Morgan <andrew@amorgan.xyz>

* Add changelog file

* Fix race when persisting create event

When persisting a chunk of DAG it is sometimes requried to do a state
resolution, which requires knowledge of the room version. If this
happens while we're persisting the create event then we need to use that
event rather than attempting to look it up in the database.

* Tweak code coverage settings

* Fix manifest

* Newsfile

* Fix commit status?

* Remove redundant WrappedConnection

The matrix federation client uses an HTTP connection pool, which times out its
idle HTTP connections, so there is no need for any of this business.

Just got very confused about the fact that the headers are only an output, not
an input.

Update Dependencies

Since 0.13.0, pymacaroons works correctly with pynacl, so there
isn’t any more reason to depend on an outdated pynacl fork.

ALL_USER_TYPES should be a tuple

turns out that 0.34.1.1+1 comes before 0.34.1.1+bionic (etc).

The version may only contain "~ 0-9 A-Z a-z + - ." (sorting in that order).

Option 1: replace "+" with something that sorts after +. Options are "-" (but
dpkg-source complains about that) or "." (but that would mean we couldn't
distinguish packaging-only changes from real changes).

Option 2: stick with + and just find something that sorts after 'xenial'. The
only options there are "-", "." (same problems as before), "z", and "+".

Hence, ++1. Sorry.

Rewrite this in python so that it can be run in parallel.

* Remove non-functional python3.6 in travis env

Otherwise people can't upgrade from matrix-synapse without removing it first
