Avoid lock contention between receiving CPUs

The single PutList/GetList for cached NET_BUFFER_LIST structures is
currently a point of contention. This patch gets rid of the contention
by keeping per-CPU GetLists.

To access the definition of HVM_MAX_VCPUS, the hvm_info_table.h header
needs to be pulled in the from the Xen source base. This patch therefore
adds the infrastructure for pulling in Xen headers.
