[gentoo-dev] [patch] golang-vcs-snapshot.eclass: add vendoring of external dependencies

[William Hubbs]

All,

things like this are already being done in the tree (by app-admin/consul
for example), and I'n sure by other go ebuilds as well.

I would like to add this functionality to golang-vcs-snapshot.eclass as
a way to remove duplicate code from ebuilds and make this available to
other ebuilds as well.

If there are no objections, I'll commit on Sunday after the council
meeting.

William
