No reason not to support both.

Right now we attempt to redirect them before we do all the boring ping
stuff. If they have buffering this doesn't work though.
We should combine the lookups, there's no reason to request X links for
pingback and then request the same X links for enclosures. Ideally:
* Set very low timeout, like around a second
* Do HEAD request first
* If audio/*, video/*, etc and on the same domain, enclose
* If link was marked up with rel="enclosure", enclose\
* If x-pingback: header, pingback it
* If text/* or application/xhtml+xml grab first 10k then
* Look for pingback <meta>, if there send and move on
* Look for rel="trackback"
* Look for trackback RDF
