Ingo Weinhold 6a1430716c BDaemonClient: Add support for creating activation transactions
* BActivationTransaction:
  - Remove non-trivial constructor.
  - Remove package list parameters from SetTo().
  - Add AddPackageTo{Dea,A}ctivate().
* BDaemonClient:
  - Add CreateTransaction(). It creates a transaction directory and
    initializes a BActivationTransaction. Packages to de-/activate have
    to be added afterwards.
  - Add BCommitTransactionResult::FullErrorMessage().
