Support for unix sockets

[Sir-Photch]

For a self-hosted scenario, it is quite likely that both homeserver and bridge are operated on the same server. For this, it would be quite handy if both the bridge could connect through the unix-socket of the homeserver via the address-parameter in the configuration and the homeserver could make use of a socket opened up by the bridge to connect to the appservice.

What do you think?

Unix sockets are already supported

[Sir-Photch]

And how do you specify them?

setting homeserver:address: to unix:/path/to/the.sock returns

FTL /whoami request failed with unknown error error="failed to GET /_matrix/client/v3/account/whoami: M_UNKNOWN (HTTP 500): Internal server error"

using synapse 1.92.1 (maybe a homeserver issue matrix-org/synapse#16396)

and apparently, the spec doesnt specify to be able to connect to an appservice through an unix socket.
