*: add module context machinery
introduces create_context() and destroy_context() methods, and adds a 'void *context' first parameter to the module methods. If a module doesn't supply create_context() then NULL is simply passed around as the context, so trivial modules can continue to only implement render_fragment(). A subsequent commit will update the modules to encapsulate their global state in module-specific contexts.
