$(PYTHON) is a Make variable which is set by configure.
In all other places over the tree, .py files are run from
Makefiles using this variable, except of a single leftover
in hw/i386/Makefile.obj (and a nearby place in there uses
$(PYTHON) correctly). Fix this leftover too.

This adds C code for generating ACPI tables at runtime,
imported from seabios git tree
commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd
Although ACPI tables come from a system BIOS on real hw,
it makes sense that the ACPI tables are coupled with the
virtual machine, since they have to abstract the x86 machine to
the OS's.
This is widely desired as a way to avoid the churn
and proliferation of QEMU-specific interfaces
associated with ACPI tables in bios code.
Notes:
As BIOS can reprogram devices prior to loading
ACPI tables, we pre-format ACPI tables but defer loading
hardware configuration there until tables are loaded.
The code structure was intentionally kept as close
to the seabios original as possible, to simplify
comparison and making sure we didn't lose anything
in translation.
Minor code duplication results, to help ensure there are no functional
regressions, I think it's better to merge it like this and do more code
changes in follow-up patches.
Cross-version compatibility concerns have been addressed:
ACPI tables are exposed to guest as FW_CFG entries.
When running with -M 1.5 and older, this patch disables ACPI
table generation, and doesn't expose ACPI
tables to guest.
As table content is likely to change over time,
the following measures are taken to simplify
cross-version migration:
- All tables besides the RSDP are packed in a single FW CFG entry.
This entry size is currently 23K. We round it up to 64K
to avoid too much churn there.
- Tables are placed in special ROM blob (not mapped into guest memory)
which is automatically migrated together with the guest, same
as BIOS code.
- Offsets where hardware configuration is loaded in ACPI tables
are also migrated, this is in case future ACPI changes make us
rearrange the tables in memory.
This patch reuses some code from SeaBIOS, which was originally under
LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This
relicensing has been acked by all contributors that had contributed to the
code since the v2->v3 relicense. ACKs approving the v2+ relicensing are
listed below. The list might include ACKs from people not holding
copyright on any parts of the reused code, but it's better to err on the
side of caution and include them.

This adds a dynamic bios linker/loader.
This will be used by acpi table generation
code to:
- load each table in the appropriate memory segment
- link tables to each other
- fix up checksums after said linking

Detect presence of IASL compiler and use it
to process ASL source. If not there, use pre-compiled
files in-tree. Add script to update the in-tree files.
Note: distros are known to silently update iasl
so detect correct iasl flags for the installed version on each run as
opposed to at configure time.

pc q35 based chipset emulator to support pci express natively. Based on
Anthony Liguori's suggestion, the machine name is 'q35-next', with an alias
of 'q35'. At this point, there are no compatibility guarantees. When the
chipset stabilizes more, we will begin to version the machine names.
Major features which still need to be added:
-Migration support (mostly around ahci)
-ACPI hotplug support (pcie hotplug support is working)
-Passthrough support
