A little while ago, Jeremy Fitzhardinge has a problem that was preventing
request-abs-pointer from being honoured.  A simple fix for this in
805ed3b20492d2f4bb465bfda65cedd286e23209 actually turned out to be wrong.

Konrad Rzeszutek Wilk and Stefano Stabellini suggested a different
approach: introduce a new hook in xen_backend that, if defined, is called
when the frontend is connected.  The first of these two patches does just
that (the old connect hook is now called "initialise" and the new hook is
called "connected").   The second patch uses this to set up the pointer at
the right time.   I haven't been able to test this in a Xen 4.0
environment, but it works properly in a Xen 3.4 environment.
