match: split up main matcher into patternmatcher and includematcher

At this point the includematcher is an exact copy of the main matcher
class. We will specialize and simplify both classes in the following
patches. This initial unmodified copy is just to make the differences
clearer. We also rename the main matcher to "patternmatcher" for
consistency.

I may eventually merge this new includematcher back into the main
matcher, but I think doing it this way makes the intermediate steps
clearer regardless.
