[v2,09/10] pakfire: Add getmetadata function
Commit Message
- Added new getmetadata function for easy access to all available
metadata of a pak without knowledge about or need to parse
pakfire internal db files.
- Added new 'pakfire info' functionality for displaying all available
metadata of (a) pak(s) to the user, using the new getmetadata.
