/**********************
* Transaction Scores *
**********************
*
* In order to allow instance counts to be adjusted properly when an
* autorollback transaction is ran, we keep a list that is indexed
* by rpm name of whether the rpm has been installed or erased. This listed
* is only updated:
*
* iif autorollbacks are enabled.
* iif this is not a rollback or autorollback transaction.
*
* When creating an autorollback transaction, its rpmts points to the same
* rpmtsScore object as the running transaction. So when the autorollback
* transaction runs it can see where each package was in the running transaction
* at the point the running transaction failed, and thus on a per package
* basis make adjustments to the instance counts.
