The empty string is a valid setting for the bind_address option, so
explicitly check for None here instead.

Some streams will occaisonally advance their positions without actually
having any new rows to send over federation. Currently this means that
the token will not advance on the workers, leading to them repeatedly
sending a slightly out of date token. This in turns requires the master
to hit the DB to check if there are any new rows, rather than hitting
the no op logic where we check if the given token matches the current
token.
This commit changes the API to always return an entry if the position
for a stream has changed, allowing workers to advance their tokens
correctly.
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.
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.
Renames ``load_config`` to ``load_or_generate_config``
Adds a method called ``load_config`` that just loads the
config.
The main synapse.app.homeserver will continue to use
``load_or_generate_config`` to retain backwards compat.
However new worker processes can use ``load_config`` to
load the config avoiding some of the cruft needed to generate
the config.
As the new ``load_config`` method is expected to be used by new
configs it removes support for the legacy commandline overrides
that ``load_or_generate_config`` supports
