Bug#852417: unblock: qemu/1:2.8+dfsg-2

[Michael Tokarev <mjt@tls.msk.ru>]

After some thoughts, I think this should be pushed to testing
faster. Because the features I enabled which are currently
in testing are just plain buggy, there are multiple security
bugs in virtio-3d display (which is being disabled in sid),
and because with just 2 weeks of this being in testing, it
will come to a big surprize for users if it hits stretch and
there will be as much complaints about new dependencies as
I'm receiving now.

In short, we need 1:2.8+dfsg-2 in stretch, and the faster it
will be there, the better, because we'll at least have some
chances (including bpo version) to see what else could be
missing/broken and fix that. I already prepared bpo version
which is waiting this version to hit testing.

Also there are a few more security fixes being accumulated,
and also a few non-security probs being worked on, which
should be in stretch, -- especially probs with migration
from older qemu.

Maintaining 1:2.8+dfsg-1 (with gtk and 3d) in stretch will
be difficult.

I understand this is my fault to enable large features this
close to the release, hence I'm trying to fix that before
it is too late.  I waited for upstream 2.8 version in a hope
there will be modular display support so it'll be possible
to make graphics packages/dependencies optional, but these
patches weren't accepted.

Please consider shortening the waiting period for this version.

Thank you!
