Come up with an awesome way to manage nobuild files

[jdreed]

We should do something better with nobuild files. In particular, we primarily use them for cluster vs not-cluster, so we should come up with a way to flag packages as cluster (in their control files, maybe?) and have a master file that lists what versions we support cluster on.

See also #875 #862

Per discussion at release-team, I'd like to proposed that instead of nobuild files, we honor the following fields in control:

XSC-DebathenaBuildFor?
XSC-DebathenaNoBuild?

And the following patches to daupload-proposed and sbuildhack:

Deployed to the locker.

[jdreed]

NAK, the current code in daupload-proposed doesn't work, because XSC fields don't get copied to the source changes file, only the binary ones.

[jdreed]

Right, well, that didn't work. New plan. Revert sbuildhack and daupload-proposed, and instead write out the nobuild files in dasource, based on X-whatever fields in the control file. The fields need not be propagated to the source and changes files.

[jdreed]

Possibly re-fixed in r25498

TTL expired, deployed, tested, functional.
