We discussed this on IRC.   I really dislike the multiple source lines
"downloading" the same file approach.

An idea is doing:

source=("mirror://file.tar.gz")
mirror=("http://foo.com/" "http://bar.com/")

makepkg would replace "mirror://" in the source line with a value from
the "mirror" array and try downloading from each one until success or
total failure.

To allow multiple sources to have different mirrors, I am proposing we
detect an unknown protocol in the url and look for the corresponding
array.  e.g. we could have source=("sourceforge://file.tar.gz") and look
for the "sourceforge" array.

Comments or other ideas?
