1. Removes intercept of guest-specific MSRs
MSR_IA32_SYSENTER_{CS,ESP,EIP}, MSR_{L,C,}STAR, MSR_SYSCALL_MASK,
MSR_SHADOW_GS_BASE.
2. Removes code to deal with those intercepts, as well as the
FS/GS-base. Since long_mode_do_msr_read now became essentially a
switch of a single case + default, I removed the entire function and
inlined the remaining single case-statement into the original
MSR-access function.

On each rtc time update from the hvm domain, we send an ioreq request
to qemu which then updates the time offset xenstore entry. The time
offset is preserved across reboot and can be set on domain creation
by setting the rtc_timeoffset variable in a config file.

If a domain fails to restore, report back an error and close the
connection. This still leaves a confusing error from 'xm migrate' in
many cases, but it's much better than just sitting there.

Changeset 14601 removed a re.compile() map on hosts_allow,
hence breaking the tcp xmlrpc api ('str' has no attribute match
in xend-debug.log).

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.

1. Shrink stack frame for __print_symbol() by introducing a lock and
making the big arrays static.
2. Double the size of the double-fault stack.
Also fix the show_stack_overflow function.

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.

A TLB entry shouldn't be inserted into VHPT when its memory
attribute field is 001 "software reserved".
Without this patch, a TLB fault expected by a guest OS is missing.
