[OSSTEST PATCH 15/26] cr*: Support xen-unstable-smoke

[Ian Jackson <ian.jackson@eu.citrix.com>]

Add this branch to select_xenbranch.  This works like xen-unstable in
most respects.

There are only two places in osstest where xenbranch `xen-unstable' is
treated specially and only one of them needs adjusting to match
xen-unstable-smoke too.

The new branch `xen-unstable-smoke' has a `prev' branch of
`xen-unstable' according to cri-getprevxenbranch, which is technically
wrong, but this is not important because xen-unstable-smoke has no
prev tests.

We are going to sort out the push gate ref plumbing in xen.git in the
next osstest patch.

Also, use a branch-settings file to set the new branch's resource
priority to -20 to make it run ahead of anything else automatic.
