osc: 8: parse params, and the ‘id’ parameter specifically

Browse source 
Applications can assign an ID to the URL. This is used to associate
the parts of a split up URL with each other:

  ╔═ file1 ════╗
  ║          ╔═ file2 ═══╗
  ║http://exa║Lorem ipsum║
  ║le.com    ║ dolor sit ║
  ║          ║amet, conse║
  ╚══════════║ctetur adip║
             ╚═══════════╝

In the example above, ‘http://exa’ and ‘le.com’ are part of the same
URL, but by necessity split up into two OSC-8 URLs.

If the application sets the same ID for those two OSC-8 URLs, the
terminal can ensure they are handled as one.
