* PackageFileHeap{Reader,Writer} as well as Package{Reader,Writer} and
their implementation and super classes do now internally use a
BPositionIO instead of a FD to access the package file. This provides
more flexibility needed for features to come.
* BPackageReader has already grown a new Init() version with a
BPositionIO* parameter.
