48f2b00648 evdev: Remove evdev.ko linkage dependency on kbd driver
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.

3a3dc5b5b4 wmt(4): Use internal function to calculate input report size
Usbhid's hid_report_size() calculates integral size of all reports of given
kind found in the HID descriptor rather then exact size of report with given
ID as its userland counterpart does. As all input data processed by the
driver is located within the same report, calculate required driver's buffer
size with userland version, imported in one of the previous commits.
This allows us to skip zeroing of buffer on processing of each report.

While here do some minor refactoring.

6469bdcdb6 Move most of the contents of opt_compat.h to opt_global.h.
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
set of compiled files.

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

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.

0eb8d46232 Improve USB polling mode by not locking any mutexes, asserting any
mutexes or using any callouts when active.

Trying to lock a mutex when KDB is active or the scheduler is stopped
can result in infinite wait loops. The same goes for calling callout
related functions which in turn lock mutexes.

If the USB controller at which a USB keyboard is connected is idle
when KDB is entered, polling the USB keyboard via USB will always
succeed. Else polling may fail depending on which state the USB
subsystem and USB interrupt handler is in. This is unavoidable unless
KDB can wait for USB interrupt threads to complete before stalling the
CPU(s).

1a58327bc3 Fix key delay and repeat, part 2.
Use sbintime_t timeouts with precision control to get very accurate
timing.  It costs little to always ask for about 1% accuracy, and the
not so new event timer implementation usual delivers that, and when
it can't it gets much closer than our previous coarse timeouts and
buggy simple countdown.

The 2 fastest atkbd repeat rates have periods 34 and 38 msec, and ukbd
pretended to support rates in between these.  This requires
sub-microsecond precision and accuracy even to handle the 4 msec
difference very well, but ukbd asked the timeout subsystem for timeouts
of 25 msec and the buggy simple countdown of this gave a a wide range
of precisions and accuracies depending on HZ and other timer
configuration (sometimes better than 25 msec but usually more like 50
msec).  We now ask for and usually get precision and accuracy of about
1% for each repeat and much better on average.

The 1% accuracy is overkill.  Rounding of 30 cps to 34 msec instead of
33 already gives an error of +2% instead of -1%, and ut AT keyboards on
PS/2 interfaces have similar errors.

A timeout is now scheduled for every keypress and release.  This allows
some simplifications that are not done.  It allows removing the timeout
scheduling for exiting polled mode where it was unsafe in ddb mode.  This
is done.  Exiting polled mode had some problems with extra repeats.  Now
exiting polled mode lets an extra timeout fire and the state is fudged
so that the timeout handler does very little.

The sc->time_ms variable is unsigned to avoid overflow.  Differences of
it need to be signed.  Signed comparisons were emulated by testing an
emulated sign bits.  This only works easily for '<' comparisonss, but
we now need a '<=' comparison.  Change the difference variable to
signed and use a signed comparison.  Using unsigned types here didn't
prevent overflow bugs but just reduced them.  Overflow occurs with
n repeats at the silly repeat period of [U]INT_MAX / n.  The old countdown
had an off by 1 error, and the simplifications would simply count down
1 to 0 and not need to accumulate possibly-large repeat repeats.

e99472e0d6 Fix key delay and repeat, part 1.
kbdcontrol -r fast is documented to give a non-emulated atkbd's fastest
rate of 250.34, but is misimplemented to request this as 0.0.  ukbd
supports many nonstandard rates, although it is currently too inaccurate
by a factor of several hundred for non-huge nonstandard rates to be
useful.  It mapped 0.0 to 200.0.  A repeat delay of 0 means a rate of
infinity which is quite fast, but physical constraints limit this to
a few MHz and the inaccuracies made it almost usable.

Convert 0.0 to the documented 250.34.

Also convert negative args and small args to the 250.34 minimal ones,
like atkbd does.  This is for KDSETREPEAT -- the 2 versions of the
deprecated KDSETRAD have bounds checking.  Keep not doing any bounds
checking or conversions for upper limits since nonstandard large
delays are useful for testing.

The inaccuracies are dependent on HZ and the timeout implementation.
With the old timeout implementation and HZ = 1000, 200.0 probably
worked better to emulate 250.34 than 250.34 itself.  HZ = 100 gives
roundoff errors that accidentally reduce the inaaccuracies, and
event timers reduce the inaccuracies even more, so 200.0 was giving
more like itself (perhaps 215.15 on average but sometimes close to
10 msec repeat which is noticebly too fast).  This commit makes 0.0
noticeably too slow, like 250.34 always was.

ded67349a3 Further fixes for translation of PrintScreen/SysRq.
The previous fix was tested mainly on 3 AT keyboards with USB adaptors where
it works.  1 USB keyboard doesn't translate Alt-PrintScreen, so the software
has to do it.

Reorganize a little to share some code and to not translate the unusual usb
scan code0x8a unless an Alt modified is set.  Remove redundant check of Alt
modifiers.  Translation now more clearly filters out Alt-PrintScreen before
the check.

The table of errors fixed in the previous commit had many bugs.  Correct
table:

K_RAW  Ctl-PrintScreen:                                 E0-2A-E0-37 -> E0-37
K_RAW  Alt-PrintScreen (with 4 comb. of Ctl/Shift):     79 -> 54
K_RAW  Pause/Break (with 4 comb. of Alt/Shift):         E0-46 -> E1-1D-45
K_CODE PrintScreen (with 4 comb. of Ctl/Shift):         54 -> 5c
K_CODE Alt-PrintScreen (with 4 comb. of Ctl/Shift):     7e -> 54
K_CODE Pause/Break (with 8 comb. of Ctl/Alt/Shift):     6c -> 68

That is 25 of 32 shift combinations for 2 keys fixed.  All 16 combinations
were broken for K_CODE and thus also for K_XLATE.

3f7880e23a Fix translation of the PrintScreen/SysRq and Pause/Break keys. Almost
everything was broken.  The cases that I noticed were Ctrl-PrintScreen
not being mapped to the virtual scancode 0x5c (debug) and Pause not being
mapped to the physical/virtual scancode 0x46 (slock).

These keys are the most complicated ones due to kludges to give some
compatibility back to before AT keyboards.

Alt-PrintScreen must pretend to be a separate key from PrintScreen
even at the "raw" level.  The (unique) usb code for it is 0x8a and we
just have to map this to our unique virtual scancode 0x54, but we
mapped it first to the internal code 0x7e and then to 0x79 which is a
key on the Japanese 106/109 keyboard.  This fix is under the
UKBD_EMULATE_ATASCANCODE option which shouldn't be used for non-AT
keyboards.  If it is, then the syscons Japanese keymaps have nothing
of importance for code 0x79 and can easily be changed.  0x54 is also
unimportant in Japanese and US keymaps.

NonAlt-PrintScreen and NonCtl-Pause/Break had many much larger bugs with
smaller compatibility problems from fixing them.  The details are too
ugly to give here.  Summary of the changed (hex) codes:

K_RAW  PrintScreen (Ctl, Shift, Ctl-Shift):             E0-2A-E0-37 -> E0-37
K_RAW  Alt-PrintScreen (all shift states):              79 -> 54
K_RAW  Pause/Break (unshifted, Shift, Alt, Alt-Shift)): E0-46 -> E1-1D-45
K_CODE ALT-PrintScreen (all shift states):              79 -> 54

That is 15 of 32 shift combinations for 2 keys fixed, with 8 easy cases
from the 79 -> 54 remapping.

The difference is only large and with no workaround using a keymap for
for K_RAW, but this affects other modes when ukbd is layered under kbmux
because kbmux keeps all subdevices in K_RAW mode and translates.  Oops.
I used kbdmux to generate the above table of changes.

3da1cf1e88 Extend the meaning of the CTLFLAG_TUN flag to automatically check if
there is an environment variable which shall initialize the SYSCTL
during early boot. This works for all SYSCTL types both statically and
dynamically created ones, except for the SYSCTL NODE type and SYSCTLs
which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to
be used in the case a tunable sysctl has a custom initialisation
function allowing the sysctl to still be marked as a tunable. The
kernel SYSCTL API is mostly the same, with a few exceptions for some
special operations like iterating childrens of a static/extern SYSCTL
node. This operation should probably be made into a factored out
common macro, hence some device drivers use this. The reason for
changing the SYSCTL API was the need for a SYSCTL parent OID pointer
and not only the SYSCTL parent OID list pointer in order to quickly
generate the sysctl path. The motivation behind this patch is to avoid
parameter loading cludges inside the OFED driver subsystem. Instead of
adding special code to the OFED driver subsystem to post-load tunables
into dynamically created sysctls, we generalize this in the kernel.

Other changes:
- Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask"
to "hw.pcic.intr_mask".
- Removed redundant TUNABLE statements throughout the kernel.
- Some minor code rewrites in connection to removing not needed
TUNABLE statements.
- Added a missing SYSCTL_DECL().
- Wrapped two very long lines.
- Avoid malloc()/free() inside sysctl string handling, in case it is
called to initialize a sysctl from a tunable, hence malloc()/free() is
not ready when sysctls from the sysctl dataset are registered.
- Bumped FreeBSD version to indicate SYSCTL API change.
