Commit cefeffc7e5 marked ACPI tables as NVS in the hvmloader path
because SeaBIOS may otherwise just mark it as RAM. There is, however,
yet another reason to do it even in the PVH path. Xen's incarnation of
AML relies on having access to some ACPI tables (e.g: _STA of Processor
objects relies on reading the processor online bit in its MADT entry)
This is problematic if the OS tries to reclaim ACPI memory for page
tables as it's needed for runtime and can't be reclaimed after the OSPM

There are use cases (for example using the PV driver) in Dom0less
setup that require Dom0less DomUs start immediately with Dom0, but
initialize XenStore later after Dom0's successful boot and call to
the init-dom0less application.
An error message can seen from the init-dom0less application on
1:1 direct-mapped domains:
```
Allocating magic pages
memory.c:238:d0v0 mfn 0x39000 doesn't belong to d1
Error on alloc magic pages
```
The "magic page" is a terminology used in the toolstack as reserved
pages for the VM to have access to virtual platform capabilities.
Currently the magic pages for Dom0less DomUs are populated by the
init-dom0less app through populate_physmap(), and populate_physmap()
automatically assumes gfn == mfn for 1:1 direct mapped domains. This
cannot be true for the magic pages that are allocated later from the
init-dom0less application executed in Dom0. For domain using statically
allocated memory but not 1:1 direct-mapped, similar error "failed to
retrieve a reserved page" can be seen as the reserved memory list is
empty at that time.
Since for init-dom0less, the magic page region is only for XenStore.
To solve above issue, this commit allocates the XenStore page for
Dom0less DomUs at the domain construction time. The PFN will be
noted and communicated to the init-dom0less application executed
from Dom0. To keep the XenStore late init protocol, set the connection
status to XENSTORE_RECONNECT.
Since the guest magic region allocation from init-dom0less is for
XenStore, and the XenStore page is now allocated from the hypervisor,
instead of hardcoding the guest magic pages region, use
xc_hvm_param_get() to get the XenStore page PFN. Rename alloc_xs_page()
to get_xs_page() to reflect the changes.
With this change, some existing code is not needed anymore, including:
(1) The definition of the XenStore page offset.
(2) Call to xc_domain_setmaxmem() and xc_clear_domain_page() as we
don't need to set the max mem and clear the page anymore.
(3) Foreign mapping of the XenStore page, setting of XenStore interface
status and HVM_PARAM_STORE_PFN from init-dom0less, as they are set
by the hypervisor.
Take the opportunity to do some coding style improvements when possible.

corrupt later parts.
This was an unexpected discovery while trying to test Xen's gunzip()

In both cases, a VM booted on a security-patched Xen 4.13, and then migrated
on to any newer version of Xen on the same or compatible hardware would have
these features stripped back because Xen is still editing the cpu-policy for
