Refactor to eliminate duplicated rate and delay tables, with minor style

convert from microseconds to ticks (that's done elsewhere). Remove
traiing whitespace in kbdcontrol.c.

Except for the new warning, no change in behavior

sys/kbio.h: make pre-unicode keymap support optional

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 Unicode characters in keymap dead key tables

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.

atkbd(4): Fix "hancha" and "han/yong" korean keys handling.

The Korean keyboard has two keys, the Korean/Chinese and the
Korean/English toggles, that generate scancodes 0xF1 and 0xF2
(respectively) when pressed, and nothing when released. They do not
repeat.
As Hanyong/Hancha keys are generally greater than 0x80, which is
generally considered a release key, add extra preceding press key event
to generate press/release pair.
Swap Hanyong/Hancha key codes to match reality.

In my understanding this is only needed to workaround lost interrupts.
I was thinking to remove it completely, but the comment about edge-
triggered interrupt may be true and needs deeper investigation. ~1Hz
should be often enough to handle the supposedly rare loss cases, but
rare enough to not appear in top. Add sysctl hw.atkbd.hz to tune it.

Move evdev_ev_kbd_event() helper from evdev to kbd.c as otherwise evdev
unconditionally requires all keyboard and console stuff to be compiled
into the kernel. This dependency happens as evdev_ev_kbd_event() helper
references kbdsw global variable defined in kbd.c through use of
kbdd_ioctl() macro.

While here make all keyboard drivers respect evdev_rcpt_mask while setting
typematic rate and LEDs with evdev interface.

opt_compat.h is mentioned in nearly 180 files. In-progress network
driver compabibility improvements may add over 100 more so this is
closer to "just about everywhere" than "only some files" per the
guidance in sys/conf/options.

Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of
sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h
is created on all architectures.

Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
