Again, this enables reuse when preparing per-table fw_cfg blobs later.

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.
Affected SeaBIOS files (GPLv2+ license headers added)

The patch incorporates ideas/suggestions from Michael Tsirkin's prototype
code:
- "hw/i386/pc.c" is too big, create new file "hw/i386/acpi.c" with
i386-specific ACPI table stuff,
- separate preparation of individual tables from their installation as
fw_cfg files,
- install these fw_cfg files inside pc_memory_init(), which is shared by
piix4/q35,
- add the above licensing-related block to the commit message.

Looks good to me. For patches 1-6:
Acked-by: Michael S. Tsirkin <mst@redhat.com>
For patch 7 - I'm not sure we want to ship qemu
that only supplies the MADT but not the other tables. So maybe we can
merge it disabling the functionality temporarily, until the rest of the
tables are converted? A config flag will do.
