[PATCH OSSTEST] Switch to merged qemu-xen{, -traditional}.git trees

[Ian Campbell <ian.campbell@citrix.com>]

The qemu-mainline flights now push to the upstream-tested branch of
qemu-xen.git (while still pulling from upstream).

The qemu-upstream-unstable flights pull from staging and push to
master in qemu-xen.git

All of the qemu-upstream-X.Y-testing pull from staging-X.Y and push to
stable-X.Y branch in qemu-xen.git.

For now we also continue pushing to the old trees for qemu-upstream
4.2 through to 4.6-testing. Once those branches have updated their
Config.mk and done a point release we can consider removing these.

Abolish $LOCALREV_QEMU_MAINLINE in favour of $LOCALREV_QEMU_UPSTREAM,
it was used inconsistently.

While changing things ensure all pushes are done to refs/heads/$thing
to avoid issues when output branches to not exist.
