makepkg: Support for resuming source downloads

Browse Source 
Download to *.part and remove the suffix if successful, thus md5sums will be
checked only for complete files, and next time makepkg will resume
downloading of partial file instead of complaining about invalid md5sums.

Old DLAGENTS format is still supported.

Late fix: Do not try to download %u first

The output of grep was not suppressed, thus the output of get_downloadcmd
was wrong because of extra line at the beginning that contained an
unsubstituted (with %o and %u) entry from DLAGENTS.

well; the download URL is placed on the end of the command. This is more
flexible than the former `FTPAGENT` variable, as any protocol can have a
download agent. Several examples are provided in the default makepkg.conf.
All instances of `%u` will be replaced with the download URL. If present,
instances of `%o` will be replaced with the local filename, plus a ``.part''
extension, which allows to do file resumes properly.
