Details:


With [1] we would possibly have three options for metalink downloads:

--metalink - for urls that link to a metalink xml file 
--input-metalink - for local metalink files on local disk
--metalink-over-http - for urls that have metalink information in http
headers

I believe we could combine these all in to one option; --metalink.

Assuming wget --metalink $url is provided: 

If provided --metalink file:///path/to/file; then
   process metalink xml file and download target
else if http headers received from $url; then
   process http header metalink information and download target
else if target is xml metalink from $url
   process metalink xml file and download target
else (the $url does not reference a metalink)
   fallback to normal http download of target

We could deprecate the --input-metalink and --metalink-over-http options and
phase them out over time. Is this reasonable?
