oe.packagegroup: add code for package groups (sync from OE)
This includes some utility functions for dealing with groups of packages
defined in the metadata. Metadata syntax:
PACKAGE_GROUP_<group> = "<list of packages>"
If the packages in the group are optional:
PACKAGE_GROUP_<group>[optional] = "1"
