Anatol Pomozov 16d98d6577 Convert '-U pkg1 pkg2' codepath to parallel download
Installing remote packages using its URL is an interesting case for ALPM
API. Unlike package sync ('pacman -S pkg1 pkg2') '-U' does not deal with
server mirror list. Thus _alpm_multi_download() should be able to
handle file download for payloads that either have 'fileurl' field
or pair of fields ('servers' and 'filepath') set.

Signature for alpm_fetch_pkgurl() has changed and it accepts an
output list that is populated with filepaths to fetched packages.
