Robin Roevens March 9, 2022, 10:56 p.m. UTC
- 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.
- Use getmetadata function in services.cgi to determine installed
  addon services to display. Removing code duplication and intel that
  should only be known by pakfire itself.

Is this still a problem? Why do we even catch this here?

Not sure.. Never tested it. I will try to set up a test env with a
sound card .. not sure if I will succeed. never started a vm with sound
here before .. So if someone else can test this more easily ?

This is actually a rename of the key from 'ProgVersion' to
'AvailableProgVersion'; delete removes the key from the hash, and
returns its value, which is added to the hash as the new key
'Available...'. 
If I would remove the delete, the same info would be in the hash, once
in 'ProgVersion' and once in 'AvailableProgVersion'.
And in case the pak is not installed, it would be returned as such from
this function; while existence of 'ProgVersion'/'Release' sort of
implicates that the pak is installed. (Checks should be based on
'Installed' = yes/no but it could lead to confusion to keep them)
