Note:
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.

When memory regions overlap, priority can be used to specify
which of them takes priority. By making the priority values signed
rather than unsigned, we make it more convenient to implement
a situation where one "background" region should appear only
where no other region exists: rather than having to explicitly
specify a high priority for all the other regions, we can let them take
the default (zero) priority and specify a negative priority for the

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

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
