Mostly style-related changes to package kit:

* drop 'Haiku' namespace
* rename 'Package' namespace to 'BPackageKit'
* renamed all public classes to begin with a 'B'
* renamed BPackageKit::Roster to BPackageKit::BPackageRoster to not
  clash with the BRoster from the application kit.
* fix some instances of public headers including private ones

Some functional changes, too:
* JobQueue now removes and deletes dependants of failed jobs 
  automatically
* JobQueue supports waiting for jobs to become runnable
* added a couple of InitCheck() methods where they make sense
  and invoke those in users of these classes
