- add a 'pckgen' script to generate various OpenCAS packages like
release archives (tar, zip), RPMs (source and binary) as well as to
create version file with metadata
- add a SPEC file for RPM creation
- add Makefile targets to use 'pckgen' script through 'make <package>'
'pckgen' script has a bunch of features for package generation.
Read './pckgen --help' for more information on usage scenarios.
