Older Chromebooks have issues in their embedded controller (EC) firmware
which need working around in atkbd and atkbdc. On these systems, rather
than use a standard EC, Google used their own arm-based EC. For a while,
its firmware incorrectly implemented the i8042, requiring workaroundsd
in the driver.
Implement a heuristic recommended by MrChromebox <mrchromebox@gmail.com>
to detect them: If the bios.version starts with Google_, or the maker is
either Google or GOOGLE, assume that it's a chromebook with the affected
bios. While this isn't strictly true, the number of updated systems
without the bug is very small and this will exclude all the non-Google
coreboot user that use a standard EC. There's no simple way to test the
hardware to see if it's implemented with the buggy EC.

This is a kernel-only file, so it's safe to include opt_kbd.h. However,
add #ifdef _KERNEL guards to emphasize that. And also move the include
of opt_kbd.h in atkbdcreg.h to inside the kernel guards. Nothing outside
the kernel in tree uses the rest of that file, but I'm less comfortable
moving the #ifdef _KERNEL to the top of that file.

FreeBSD-9 had introduced support for the full set of Unicode
characters to the parsing and processing of keymap character tables.
This support has been extended to cover the table for accented
characters that are reached via dead key combinations in FreeBSD-13.2.
New ioctls have been introduced to support both the pre-Unicode and
the Unicode formats and keyboard drivers have been extended to support
those ioctls.
This commit makes the ABI compatibility functions in the kernel
optional and dependent on COMPAT_FREEBSD13 in -CURRENT.
The kbdcontrol command in -CURRENT and 13-STABLE (before 13.2) has
been made ABI compatible with old kernels to allow a new world to be
run on an old kernel (that does not have full Unicode support for
keymaps).
This commit is not to merged back to 12-STABLE or 13-STABLE. It is
part of review D38465, which has been split into 3 separate commits
due to different MFC and life-time requirements of either commit.

Support for Unicode characters had been added to the keyboard code,
but there are keymaps that have accented characters accessed via dead
key combinations, and those were still restricted to 8 bit codes.
This update to kbd.c adds support for Unicode characters and
compatibility code that allows a kbdcontrol command built from kbio.h
without these patches to work on a new kernel.
Compatibility code that allows a new kbdcontrol binary running on an
old kernel to load and display the dead key map will be committed in a
separate commit.

In my understanding this is only needed to workaround lost interrupts.
I was thinking to remove it completely, but the comment about edge-

r123442 introduced solution for clamping of PS/2 mice jitter when using
a KVM. Solution is to buffer mouse packets for 0.050ms if mouse activity
has not been seen for more than 0.5 seconds. Then flush that data to driver
if no validation errors found or drop the entire queue otherwise.
While it works well with relative devices it has issues with absolute ones
Depending on history buffering may results in delaying of the touch front
edge for 0.050ms that affects gesture processing (tap detection).
As absolute touchpads usually are built-in devices we can safely disable
bufferization and KVM jitter clamping to avoid such a delays.

This most importantly reduces duplication, but it also removes any potential
race with usage of dev->si_drv1 since it's now set prior to the device being
constructed enough to be accessible.
Proper locking for atkbdc will likely replace the kbdc_lock mechanism
entirely with a mutex in atkbdc_softc, so that other consumers can also
properly ensure locking protocol is followed (e.g. psm.c:doinitialize).
The first step to doing this neatly is making KBDC less opaque so that
others don't have to jump through weird casting hoops to address the mutex.
No functional change intended; this diff effectively just removes a bunch of
casting. A future change may remove the KBDC typedef entirely and just opt
for using `atkbdc_softc_c *` directly, but this was decidedly a good
intermediate step to make these changes simple to audit.
Most keyboard drivers are using the genkbd implementations as it is;
formally use them for any that aren't set and make
genkbd_get_fkeystr/genkbd_diag private.
A future change will provide default implementations for some of these where
it makes sense and most of them are already using the genkbd
implementation (e.g. get_fkeystr, diag).
Enable synaptics and elantech touchpads, as well as IBM/Lenovo TrackPoints
by default, instead of having users find and toggle a loader tunable.
This makes things like two finger scroll and other modern features work out
of the box with X. By enabling these settings by default, we get a better
desktop experience in X, since xserver and evdev can make use of the more
advanced synaptics and elantech features.
