First go at refactoring the API mechanisms

This introduces an ApiCall class that wraps around the actual method
that produces the result. This replaces various loose array structures
that provided the meta information before.

The ApiCall streamlines the aggregation of meta information between core
and plugin methods. Now all data is produced by Reflection based
introspection. Certain aspects can be overridden if needed. See
ApiCore::getRemoteInfo() for examples

This change removes the _getMethods() method from remote plugins and
introduces a getMethods() method. The two are NOT compatible as the
latter now returns a list of ApiCalls. However when looking at the
existing plugins, it seems that _getMethods() was nearly 100% obsolete
with the Reflection based default implementation. So most plugins will
not be affected at all. Some might now export one or two more methods
than before because of poor visibility settings (eg. not declaring
private/protected methods as such).

This change removes the RPC_CALL_ADD hook. Only a single plugin ever
implemented it. I'm not sure what this hook was supposed to do anyway.
Being able to declare arbitrarily named API endpoints seems wrong to me
anyway.

The new ApiCall now also supports passing named instead of positional
parameters. This will open up a new opportunity to get a proper openapi
spec running.

Next step is fixing the tests.
