Fully assume that the method constructors use reference counting.
Otherwise, we may leak memory, or loose track and do a double free.

This queries the provider for its available functionality (unless a
matching method structured is already cached, in which case that's
used instead), and creates method structure with the help of a passed
constructor. The result is cached if the provider allows it (or if
caching is forced).
