The KDSKBSTATE ioctl brings the LED up. However, some keyboards (like qemu
keyboard) may not have LED or failed to set the LED due to unexpected reason.
Therefore, removing the error check as ukbd(4) does allow the keyboard works
correctly with kbdcontrol(4).
Also move hw.hid.hkbd.no_leds sysctl out of HID_BUG thus users can
disable setting LEDs

While FIDO/U2F keys were already supported by the generic uhid(4) and
hidraw(4) drivers, this driver adds some additional features an does
steps to tighten the security of FIDO/U2F access.
- It automatically loads through devd.
- Automatically enables HQ_NO_READAHEAD for FIDO/U2F devices.
- Implements only miminum set of features.
- Do not requires external devfs configuration to set character device
permissions.
- Names character device as u2f/# to make possible capsicum or any
other pledge()-style sandboxing.

It disables interrupt emulation on poll-driven buses like USB and
forces aquiring of only one USB frame per read(2) operation.
This avoids an FIDO/U2F issue where IN endpoint data received from
the device right before the file handle is closed, gets lost.

to Linux hidraw compatibility API.
Respective Linux commit f43d3870cafa made by Dean Camera message is:
Currently the hidraw module can only read and write feature HID reports on
demand, via dedicated ioctls. Input reports are read from the device through
the read() interface, while output reports are written through the write
interface().
This is insufficient; it is desirable in many situations to be able to read and
write input and output reports through the control interface to cover
additional scenarios:
- Reading an input report by its report ID, to get initial state
- Writing an input report, to set initial input state in the device
- Reading an output report by its report ID, to obtain current state
- Writing an output report by its report ID, out of band
This patch adds these missing ioctl requests to read and write the remaining
HID report types. Note that not all HID backends will neccesarily support this
(e.g. while the USB link layer supports setting Input reports, others may not).
FreeBSD native uhid(4) compatible API already has similar ioctls.

The current quirk is designed to discard duplicated data read from
the chip. Problem is, it also discards real events when they happen
to be identical, which is the case with scroll wheel events;
differently from X/Y they always move by fixed offset. This results
in two-finger scroll that would stop mid-way that could be fixed by
manually setting dev.hms.0.drift_thresh to 0.
To fix that, don't discard duplicates when there's wheel movement.
For users with actual duplicates problem this will result in scroll
suddenly becoming quite inertial, but it will stop moving at any touch,
so shouldn't be terrible.

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.
