Use similar naming we use in email notifs for push

Reading the RST spec, I was trying to get breaks to appear by entering the double spaces after the lines in the code blocks. It does not work anyway, and, as pointed out, I've removed.

Additionally it does not appear there is turnserver.conf.default, but rather, just /etc/turnserver.conf.

Fix the sytests to use a port-range rather than a port base

Put most recent 20 messages in notif

otherwise we'll end up returning the wrong 20

Rewrite LDAP Authentication against ldap3

Use the pure-python ldap3 library, which eliminates the need for a
system dependency.

Offer both a `search` and `simple_bind` mode, for more sophisticated
ldap scenarios.
- `search` tries to find a matching DN within the `user_base` while
  employing the `user_filter`, then tries the bind when a single
  matching DN was found.
- `simple_bind` tries the bind against a specific DN by combining the
  localpart and `user_base`

Offer support for STARTTLS on a plain connection.

The configuration was changed to reflect these new possibilities.

Optionally start or stop workers in synctl.

Optionally start or stop an individual worker by passing -w with
the path to the worker config.
Optionally start or stop every worker and the main synapse by
passing -a with a path to a directory containing worker configs.

The "-w" is intended to be used to bounce individual workers proceses.
THe "-a" is intended for when you want to restart all the workers
simultaneuously, for example when performing database upgrades.

Remove the legacy v0 content upload API.

Fix substitution failure in mail template

The existing content can still be downloaded. The last upload to the
matrix.org server was in January 2015, so it is probably safe to remove
the upload API.

Linearize some federation endpoints based on (origin, room_id)

Remove registered_users from the distributor.
