Force P2M top-level page table to be allocated below 4GB
memory space when Xen is running under PAE mode. Also remove
hap.p2m_freelists because hap mode does not have P2M batch
allocation. The backpointer parameter of hap_alloc() function is
removed since this parameter is unused.

qcow2raw would hang the conversion just short of 100%, because the
final write queue was never being submitted. If a blktap drivers read
synchronously, then "submit_events" and "complete" variables are
checked before getting set, so the fact that reads have finished is
not noticed, so the final write queue was never submitted.
Note that I have also removed the variables write_complete and
read_complete. They were unused, and they were also not set correctly
in the synchronous case.

This patch prevents writing empty configuration items to the domain's

for 'xm dumppolicy' has been adapted to show which entry in the binary
policy is used by domain-0.
