* Use enums/constants/functions instead of preprocessor macros. * Missing include in PackageInfoAttributeValue.h. * PackageReaderImpl::Init(): Check version before header size and return B_MISMATCHED_VALUES instead of B_BAD_DATA, if the version doesn't match. This allows callers to determine the condition and try a reader for a different version. A more flexible interface for that case would be nice, but since we want to support the old package version only temporarily, the current solution should be good enough.
