Please unblock package seabios

[ Reason ]
This debian release syncronizes with the upstream stable/bugfix
release of 1.16.2.  Previous debian release of this package had
1.16.1 difference as a patch because upstream forgot to publish
the tarball.  1.16.2-1 has exactly the same stuff the previous
debian revision had (1.16.1), plus two more changes from upstream
stable/bugfix release 1.16.2.

One of the changes is a bugfix for usb hid devices init (which
I've hit myself but thought it's some difficult to diagnose
QEMU bug). It's definitely worth to have this one on bookworm.

The second change is not strictly necessary for bookworm, but
I thought there's no good reason to remove it from the upstream
stable/bugfix release.  It is related to the way how seabios
detects Xen, for the rare HVM Xen domU.  This change will be
useful for more recent qemu (8.0+) though.

[ Impact ]
There's a relatively small issue with USB HID devices init which
can only trigger in certain configurations, which will be unfixed.
Plus it will be just a bit more work for the further package
maintenance.

[ Tests ]
I tested the new bios package locally with both qemu (bookworm
one and the next version), *and* with actual Xen HVM domU, the
change does not break my setups, but allows new qemu to run
Xen HVM domains too.  Upstream has it integrated into the QEMU
CI tests.

[ Risks ]
I don't see much risks with this change. All involved code paths
are quite well tested.

[ Checklist ]
  [X] all changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in testing

[ Other info ]
Unfortunately the debdiff isn't very useful due to 1.16.1=>upstream
source move.  So I'm also adding the diff with patches applied,
which shows only the 2 changes I mentioned above.  First comes the
diff, next comes the debdiff.

-Subject: [PATCH 2/9] reset: force standard PCI configuration access
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-After a reset of a QEMU -machine q35 guest, the PCI Express
-Enhanced Configuration Mechanism is disabled and the variable
-mmconfig no longer matches the configuration register PCIEXBAR
-of the Q35 chipset. Until the variable mmconfig is reset to 0,
-all pci_config_*() functions no longer work.
-
-The variable mmconfig is located in one of the read-only C-F
-segments. To reset it the pci_config_*() functions are needed,
-but they do not work.
-
-Replace all pci_config_*() calls with Standard PCI Configuration
-Mechanism pci_ioconfig_*() calls until mmconfig is overwritten
-with 0 by a fresh copy of the BIOS.
-
-This fixes
-
-In resume (status=0)
-In 32bit resume
-Attempting a hard reboot
-Unable to unlock ram - bridge not found
-
-and a reset loop with QEMU -accel tcg.

-Subject: [PATCH 3/9] malloc: use variable for ZoneHigh size
-
-Use the variable highram_size instead of the BUILD_MAX_HIGHTABLE #define
-for the ZoneHigh size. Initialize the new variable with the old #define,
-so behavior does not change.
-
-This allows to easily adjust the ZoneHigh size at runtime in a followup
-patch.

-
-Bump default from 8 to 64 blocks.  Using 8 by default leads
-to requests being splitted on qemu, which slows down boot.
-
-Some (temporary) debug logging added showed that almost all
-requests on a standard fedora install are less than 64 blocks,
-so that should bring us back to 1.15 performance levels.

-SeaBIOS fails to parse ISA bridge AML with:
-
-   parse_termlist: parse error, skip from 92/517

-   ACPI: no PS/2 keyboard present

-due to Alias term in DSDT which isn't handled by SeaBIOS properly.
-Add dumb Alias parsing which just skips over term,

-Subject: [PATCH 9/9] virtio: finalize features before using device
-
-Under the standard of Virtio 1.0, the initialization process of the
-device must first write sub-features back to device before
-using device, such as finding vqs.
-
-There are four places using vp_find_vq().
-
-1. virtio-blk.pci:    put the code of finalizing features in front of using 
device
-2. virtio-blk.mmio:   put the code of finalizing features in front of using 
device
-3. virtio-scsi.pci:   is ok
-4. virtio-scsi.mmio:  add the code of finalizing features before vp_find_vq()
