7839ff593b pc: get rid of builtin pvpanic for "-M pc-1.5"
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.

7f1bb742be pc: disable pci-info
The BIOS that we ship in 1.7 does not use pci info
from host and so far isn't going to use it.
Taking in account problems it caused see 9604f70fdf and
to avoid future incompatibility issues, it's safest to
disable that interface by default for all machine types
including 1.7 as it was never exposed/used by guest.
And properly remove/cleanup it during 1.8 development cycle.

0624c7f916 e820: pass high memory too.
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.

72c194f7e7 i386: ACPI table generation code from seabios
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.

7174e54cf1 kvmvapic: Prevent reading beyond the end of guest RAM
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.

fc3b32958a smbios: Make multiple -smbios type= accumulate sanely
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.

ec2df8c10a smbios: Improve diagnostics for conflicting entries
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
    qemu-system-x86_64: -smbios type=1,serial=42,serial=99: This is the conflicting setting
