Merge lp:~vorlon/xdeb/xdeb-graph-build-dep-deps into lp:~wookey/xdeb/xdeb-graph

[Steve Langasek]

Here's a branch for the fix I mentioned earlier today: with --only-explicit
and the xdeb-graph branch, xdeb currently overlooks the dependencies of
libfoo1, where bar build-depends: libfoo-dev and libfoo-dev depends: libfoo1
and both libfoo-dev and libfoo1 are built from the same source package. So
we need a way to track our recursion on a binary package basis, not just a
source package basis.

I've reused the builddep_pkgs array for this purpose, but I haven't checked
what impact this has on the graphing functions. It's possible we need Yet
Another Array to track this state properly.
