[Rpm-maint] [PATCH 0/5] Add Collection Support

[Steve Lawrence]

This patchset adds Collection support to rpm. Collections provide a way to
perform a common action after all members of that collection have been
installed. This removes duplicated post installation scripts that only need to
be executed once during a transaction.

For example, currently all font packages run /usr/bin/fc-cache in the %post
section. With collections, we can add all these font packages to the 'font'
collection, and remove the %post section. Once all members of the 'font'
collection are install, only then will fc-cache be run.

To perform collection actions, this patchset adds a minimal plugin system that
allows for both simple and complex collection actions. This system adds three
hooks that are executed at various stages of the RPM transaction to allow for
a wide range of control and flexibility. Included in this patchset is a generic
plugin that can be used to easily execute scripts, which should be sufficient
for the majority of collection actions.
