Update the plugin architecture to allow for remembering state

This moves most of the plugin logic to a new rpmplugins file with a
struct and functions for managing plugins, allowing for plugins to carry
state. This also adds init and cleanup hooks for plugins to initialize
and cleanup their state, and a new 'open te' hook allowing plugins to
read and save information from transaction elements.

This also generalizes the plugin architecture a bit so it isn't so
specific to collections.
