Subject: Use ServiceProvider for inter-module dependencies

This will stop dependency chains from preventing module reloads when
it is not actually needed; however, it removes some failsafes that will
need to be reimplemented in order to avoid unmapped vtables.

This deprecates Request as an inter-module signaling mechanism, although
SQL still uses it.
