[Xen-devel] [OSSTEST PATCH] ts-rumpuserxen-build: Cope with new layout, disabling bodges

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

The rumpsrc psuedo-submodule has been integrated with the nblibs
submodule and made into a proper submodule.

Also, in the intervening time, rumpuserxen/Config.mk now uses ?= when
setting XEN_HEADERS.

So if we detect that we have a new rumpuser-xen, we can disable:
 - ad-hoc arrangements for rumpsrc
 - grievous-bodge
 - patching Config.mk

We consider a rumpuserxen old iff it has nblibs as a submodule and
lacks rumpsrc as a submodule.

We have to have a different name for the rumpsrc submodule (rather
than using rumpsrc), because in the new arrangements it needs to be
fetched from the location specified in rumpuserxen's .gitmodules
rather than our own configured location for the old rumpsrc.  (And the
local name is in the runvars etc.)

The old runvars etc. for rumpsrc need to stay around to cope with old
rumpuserxen, for now, but are going to be obsolete.  Leave some
comments about this in relevant places.
