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" (From OE-Core rev: 4df212e9c2a1dd7c80d180fd13b67e9f2799d3e1) Signed-off-by: Chris Larson <chris_larson@mentor.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
