The LoPAPR specification defines the following for the RTAS
power-off call: "On successful operation, does not return".
However, the implementation in QEMU currently returns and runs
the guest CPU again for some more cycles. This caused some
trouble with the new ppc implementation of the kvm-unit-tests
recently. So let's make sure that the QEMU implementation
follows the spec, thus stop the CPU to make sure that the
RTAS call does not return to the guest anymore.

Commit 4b23699 "pseries: Add pseries-2.6 machine type" added a new
SPAPR_COMPAT_2_5 macro in the usual way. However, it didn't add this
macro to the existing SPAPR_COMPAT_2_4 macro so that pseries-2.4
inherits newer compatibility properties which are needed for 2.5 and
earlier.
This corrects the oversight.

With HV KVM, the guest's hash page table (HPT) is managed by the kernel and
not directly accessible to QEMU. This means that spapr->htab is NULL
and normally env->external_htab would also be NULL for each cpu.
However, that would cause ppc_hash64_load_hpte*() to do the wrong thing in
the few cases where QEMU does need to load entries from the in-kernel HPT.
Specifically, seeing external_htab is NULL, they would look for an HPT
within the guest's address space instead.
To stop that we have an ugly hack in the pseries machine type code to
set external htab to (void *)1 instead.
This patch removes that hack by having ppc_hash64_load_hpte*() explicitly
check kvmppc_kern_htab instead, which makes more sense.

At the moment the size of the hash page table (HPT) is fixed based on the
maximum memory allowed to the guest. As such, we allocate the table during
machine construction, and just clear it at reset.
However, we're planning to implement a PAPR extension allowing the hash
page table to be resized at runtime. This will mean that on reset we want
to revert it to the default size. It also means that when migrating, we
need to make sure the destination allocates an HPT of size matching the
host, since the guest could have changed it before the migration.
This patch replaces the spapr_alloc_htab() and spapr_reset_htab() functions
with a new spapr_reallocate_hpt() function. This is called at reset and
inbound migration only, not during machine init any more.

At present we calculate the recommended hash page table (HPT) size for a
pseries guest just once in ppc_spapr_init() before allocating the HPT.
In future patches we're going to want this calculation in other places, so
this splits it out into a helper function. While we're at it, change the
calculation to use ctz() instead of an explicit loop.

When migrating the 'pseries' machine type with KVM, we use a special fd
to access the hash page table stored within KVM. Usually, this fd is
opened at the beginning of migration, and kept open until the migration
is complete.
However, if there is a guest reset during the migration, the fd can become
stale and we need to re-open it. At the moment we use an 'htab_fd_stale'
flag in sPAPRMachineState to signal this, which is checked in the migration
iterators.
But that's rather ugly. It's simpler to just close and invalidate the
fd on reset, and lazily re-open it in migration if necessary. This patch
implements that change.
This requires a small addition to the machine state's instance_init,
so that htab_fd is initialized to -1 (telling the migration code it
needs to open it) instead of 0, which could be a valid fd.
