public and private API (still far from ideal, but a start): * moved several HPKG-classes into the public namespace BPackageKit::HPKG * added fImpl-wrappers around PackageReader and PackageWriter to hide most of the gory details * adjusted 'package'-binary and packagefs accordingly git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40320 a95241bf-73f2-0310-859d-f6bbb57e9c96
