Determine when to perform Collection actions

Determine when to perform Collection actions

There are three times during a transaction when Collection actions can be
performed:

1) After the last time a member of a collection is either installed or removed
2) After the last time a member of a collection is installed only
3) Before the first time a member of a collection is removed only

This patch adds three lists to the rpmte structure to mark which transaction
elements fall into each of these groups, and the collections that caused that.
A new function is added to the TSM to scan through all the transaction elements
and update these lists. When a collection is added to one of these lists, it
signifies that when that transaction element is installed, the appropriate
action should be performed for that collection.
