Support Metalink.

Browse Source 
This change adds experimental Metalink support to curl.
To enable Metalink support, run configure with --with-libmetalink.
To feed Metalink file to curl, use --metalink option like this:

  $ curl -O --metalink foo.metalink

We use libmetalink to parse Metalink files.
