* Fix more tests

* Further tweaks

* Fix current state server test (sort of)

* Maybe fix appservices

* Fix client API test

* Include database connection string in database options

* Fix sync API build

* Update config test

* Fix unit tests

* Fix federation sender build

* Fix gobind build

* Set Listen address for all services in HTTP monolith mode

* Validate config, reinstate appservice derived in directory, tweaks

* Tweak federation API test

* Set MaxOpenConnections/MaxIdleConnections to previous values

* Update generate-config
