acpi-dsdt: procedurally generate _PRT

This replaces the _PRT constant with a method that computes it.

The problem is that the DSDT+SSDT have grown from 2.0 to 2.1,
enough to cross the 8k barrier (we align the ACPI tables to 4k
before putting them in fw_cfg).  This causes problems with
migration and the pc-i440fx-2.0 machine type.

The solution to the problem is to hardcode 64k as the limit,
but this doesn't solve the bug with pc-i440fx-2.0.  The fix will be
for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the
ACPI tables.  First, however, we must make the actual AML
equal or smaller; to do this, rewrite _PRT in a way that saves
over 1k of bytecode.

pc: hack for migration compatibility from QEMU 2.0

Changing the ACPI table size causes migration to break, and the memory
hotplug work opened our eyes on how horribly we were breaking things in
2.0 already.

The ACPI table size is rounded to the next 4k, which one would think
gives some headroom.  In practice this is not the case, because the user
can control the ACPI table size (each CPU adds 97 bytes to the SSDT and
8 to the MADT) and so some "-smp" values will break the 4k boundary and
fail to migrate.  Similarly, PCI bridges add ~1870 bytes to the SSDT.

This patch concerns itself with fixing migration from QEMU 2.0.  It
computes the payload size of QEMU 2.0 and always uses that one.
The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size
should always be enough; non-AML tables can change depending on the
configuration (especially MADT, SRAT, HPET) but they remain the same
between QEMU 2.0 and 2.1, so we only compute our padding based on the
sizes of the SSDT and DSDT.

Migration from QEMU 1.7 should work for guests that have a number of CPUs
other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140.  It was already
broken from QEMU 1.7 to QEMU 2.0 in the same way, though.

Even with this patch, QEMU 1.7 and 2.0 have two different ideas of
"-M pc-i440fx-2.0" when there are PCI bridges.  Igor sent a patch to
adopt the QEMU 1.7 definition.  I think distributions should apply
it if they move directly from QEMU 1.7 to 2.1+ without ever packaging
version 2.0.

pc: acpi: generate AML only for PCI0 devices if PCI bridge hotplug is disabled

Fixes migration regression from QEMU-1.7 to a newer QEMUs.
SSDT table size in QEMU-1.7 doesn't change regardless of
a number of PCI bridge devices present at startup.

However in QEMU-2.0 since addition of hotplug on PCI bridges,
each PCI bridge adds ~1875 bytes to SSDT table, including
pc-i440fx-1.7 machine type where PCI bridge hotplug disabled
via compat property.
It breaks migration from "QEMU-1.7" to "QEMU-2.[01] -M pc-i440fx-1.7"
since RAMBlock size of ACPI tables on target becomes larger
then on source and migration fails with:

"Length mismatch: /rom@etc/acpi/tables: 2000 in != 3000"

error.

Fix this by generating AML only for PCI0 bus if
hotplug on PCI bridges is disabled and preserves PCI brigde
description in AML as it was done in QEMU-1.7 for pc-i440fx-1.7.

It will help to maintain size of SSDT static regardless of
number of PCI bridges on startup for pc-i440fx-1.7 machine type.

pc: future-proof migration-compatibility of ACPI tables

This patch avoids that similar changes break QEMU again in the future.
QEMU will now hard-code 64k as the maximum ACPI table size, which
(despite being an order of magnitude smaller than 640k) should be enough
for everyone.

acpi-build: tweak acpi migration limits

- Tweak error message for legacy machine type:
  Basically if table size exceeds the limits we set all
  bets are off for migration: e.g. it can start failing even
  within given qemu minor version simply because of a bugfix.
- Increase table size to 128k.
- Make sure we notice it long before we start getting close to the
  128k limit: warn at 64k.
- Don't fail if we exceed the limit: most people don't care about
  migration, even less people care about cross version miration.
