Clean up sync blacklist

[Jeremy Bícha]

I am attaching a bzr branch here. Because the sync blacklist is a "junk" bzr repository, Launchpad isn't letting me make a merge proposal for it.

I think it makes the blacklist easier to read and use if we get rid of all the old entries.

I went through and verified that these removals were removed from Debian.

There are a few exceptions (gdm3 and openssl1.0) which didn't need to be blacklisted anymore.

I mostly ignored the Mozilla extensions. The Mozilla situation is interesting this year, but I'll save that discussion for later.

You've dropped ccsm from the blacklist, but the sole binary package built from ccsm in Debian comes from compiz source in Ubuntu; I think this needs to be retained.

You've traded icedove for thunderbird, but why should thunderbird be blacklisted? It's currently maintained in Ubuntu and not merged from Debian but I don't see any reason in principle that it couldn't be.

Why are you dropping the blacklist of fbxkb, which was identified in the blacklist file as "obsolete GNOME panel applet"?

I am satisfied that the rest of the changes here are correct, however I would want the rationales to be better documented in the commit history. I would ask you to please:

 - rebase on the current sync-blacklist branch (there is a conflict)
 - divide the commits up according to rationale (e.g., dropped because package removed from unstable; vs dropped because package is now in Ubuntu again; vs. reshuffling of file contents)
 - resubmit

Or, you can punt this to me to do and I'll apply these changes when I have a chance.

This is answered by LP: #1811718. But still, please make this rationale apparent in the commit history.

Since this bug went to 'expired', I'll take this now, for the subset of changes I agree are appropriate.

I've landed these blacklist changes now.
