Hello,

These are some patches to add Synapse
<https://github.com/matrix-org/synapse>.

I would appreciate some help getting the tests to run for some of the
Python dependencies, they're marked with TODOs.

Synapse appears to have some optional dependencies. I haven't packaged
all of them. The remaining ones are also marked with TODOs.

But, it seems to run! Here's what I had to do to start it:

guix environment guix -- make -j4 && ./pre-inst-env guix environment synapse

cd ~/src/synapse/

python -m synapse.app.homeserver --server-name test.local --config-path /tmp/homeserver.yaml --generate-config --report-stats=no

exit

guix environment guix -- make -j4 && ./pre-inst-env guix environment --ad-hoc synapse -- synctl --no-daemonize start /tmp/homeserver.yaml
