a122d6230e xen: add some debug output for failed multicalls 
Multicalls are expected to never fail, and the normal response to a
failed multicall is very terse.  In the interests of better
debuggability, add some more verbose output.  It may be worth turning
this off once it all seems more tested.

91e0c5f3da xen: add batch completion callbacks 
This adds a mechanism to register a callback function to be called once
a batch of hypercalls has been issued.  This is typically used to unlock
things which must remain locked until the hypercall has taken place.

[ Stable folks: pre-req for 2.6.23 bugfix "xen: deal with stale cr3
  values when unpinning pagetables" ]
