    pkg: Add limited --debug/-d support
    
    Add an internal debug level global:
     - Level 1 (-d) currently does nothing.
    
     - Level 2 (-d -d) enables libfetch debugging (quite verbose) so it's
       possible to see what pkg is attempting to download without having
       to sniff traffic.
