* added kernel-compatible datatypes for reading package info attribute
values (PackageInfoAttributeValue.h) - these will be used at a later
stage by the package-fs to transport those attributes to userland
when asked to do so (by ioctl)
* implemented parsing of package info attributes in PackageReaderImpl
* added support for compressed package attribute section to
PackageReaderImpl
* completed the writing of package info attributes in PackageWriterImpl
and fixed a couple of bugs exposed by parsing
* adjusted 'package list' to show the package info attributes as they
are found
