Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.
On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.
Consider the compat and piix/q35, we finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.

After changing the parameter from `NotSerialized` to `Serialized`, the
remark is indeed gone and there is no size change.
The remark was added in ACPICA version 20130517 [1] and gives the
following explanation.
If a thread blocks within the method for any reason, and another thread
enters the method, the method will fail because an attempt will be
made to create the same (named) object twice.
In this case, issue a remark that the method should be marked
serialized. ACPICA BZ 909.

IASL stores it's revision in each table header it generates.
That's not nice since guests will see a change each time they move
between hypervisors. We generally fill our own info for tables, but we
(and seabios) forgot to do this for the built-in DSDT.
Modifications in DSDT table:
OEM ID: "BXPC" -> "BOCHS "
OEM Table ID: "BXDSDT" -> "BXPCDSDT"
Compiler ID: "INTL" -> "BXPC"

Currently, we get SeaBIOS defaults: manufacturer Bochs, product Bochs,
no version. Best SeaBIOS can do, but we can provide better defaults:
manufacturer QEMU, product & version taken from QEMUMachine desc and
name.
Take care to do this only for new machine types, of course.
Note: Michael Tsirkin doesn't trust us to keep values of QEMUMachine member
product stable in the future. Use copies instead, and in a way that
makes it obvious that they're guest ABI.
Note that we can be trusted to keep values of member name, because
that has always been ABI.

It doesn't make sense for a region to be INT64_MAX in size:
memory core uses UINT64_MAX as a special value meaning
"all 64 bit" this is what was meant here.
While this should never affect the PC system which at the moment always
has < 63 bit size, this makes us hit all kind of corner case bugs with
sub-pages, so users are probably better off if we just use UINT64_MAX
instead.

This causes two slight backwards-incompatibilities between "-M pc-1.5"
and 1.5's "-M pc":
(1) a fw_cfg file is removed with this patch. This is only a problem
if migration stops the virtual machine exactly during fw_cfg enumeration.
(2) after migration, a VM created without an explicit "-device pvpanic"
will stop reporting panics to management.
The first problem only occurs if migration is done at a very, very
early point (and I'm not sure it can happen in practice for reasonable-size
VMs, since it will likely take more time to send the RAM to destination,
than it will take for BIOS to scan fw_cfg).
The second problem only occurs if the guest panics _and_ has a guest
driver _and_ management knows to look at the crash event, so it is
mostly theoretical at this point in time.
Thus keep the code simple, and pretend it was never broken.

We have a fw_cfg entry to pass e820 entries from qemu to the firmware.
Today it's used to pass reservations only. This patch makes qemu pass
entries for RAM too.
This allows to pass RAM sizes larger than 1TB to the firmware and it
will also allow to pass non-contignous memory ramges should we decide
to implement that some day, say for our virtual numa nodes.
Obviously this needs some extra care to not break existing firware.
SeaBIOS loads the entries and happily adds them without looking at the
type. Which is problematic for memory below 4g as this will overwrite
reservations added for bios memory etc. For memory above 4g it works
just fine, seabios will merge the entry derived from cmos with the one
loaded from fw_cfg.
OVMF doesn't look at the fw_cfg e820 table.
coreboot doesn't look at the fw_cfg e820 table.

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.

rom_state_paddr is guest provided (caller address of outw(VAPIC_PORT) +
writen 16-bit value) and can be influenced to point beyond the end of
the host memory backing the guest's RAM. Make sure we do not use this
pointer to actually read beyond the limits.
Reading arbitrary guest bytes is harmless, the guest kernel has to
manage access to this I/O port anyway.

Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME. If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the
first one was used).
Multiple -smbios can add multiple fields with the same (T, NAME).
SeaBIOS reads all of them from fw_cfg, but uses only the first field
(T, NAME). The others are ignored.
"First one wins, subsequent ones get ignored silently" isn't nice. We
commonly let the last option win. Useful, because it lets you
-readconfig first, then selectively override with command line
options.
Clean up -smbios to work the common way. Accumulate the settings,
with later ones overwriting earlier ones. Put the result into fw_cfg
(no more useless duplicates).
Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by
side effect.

We allow either tables or fields for the same type. Makes sense,
because SeaBIOS uses fields only when no tables are present.
We do this by searching the SMBIOS blob for a previously added table
or field. Error messages look like this:
qemu-system-x86_64: -smbios type=1,serial=42: SMBIOS type 1 table already defined, cannot add field
User needs to know that "table" is defined by -smbios file=..., and
"field" by -smbios type=...
Instead of searching the blob, record additions of interest, and check
that. Simpler, and makes better error messages possible:
qemu-system-x86_64: -smbios file=smbios_type_1.bin: Can't mix file= and type= for same type
