[RFC] Add upstream VCS info to control file

[Gregor Jasny <gjasny@googlemail.com>]

Hello,

When one tries to fix a FTBFS bug a look into the upstream VCS is often 
helpful. Sometimes a link to browse them is easily found on the homepage 
linked from the PTS page. But often these links are deeply buried in the 
linked website.

What I'd like to see in the Debian control file are Vcs-Upstream fields 
that work like their Vcs- pendents but point to the upstream sources. 
These URLs would also be linked in the PTS.

Does this sound reasonable?

Thanks,
Gregor
