Detailed Description

PMPackageManager helper to collect disk usage info.

The per package diskusage calculation perdormed by PkgDuSlave is based on the set of mountpoint data held within the PkgDuMaster.

Asserted: The set of MountPoints is alphabetically ordered by MountPoint::_mountpoint.

Asserted: Whenever the set of MountPoints changes (add/remove mountpoints or changing a mountpoints _blocksize value), PkgDuMaster::_count must be incremented.
