Fix kbdd_diag definition

This is a direct commit to stable branches as these have been converted to
inline functions in head, which will likely not get MFC'd due to limited
utility -- follow up locking assertions likely cannot be done in stable
branches.

The use of 'level' in the macro definition was truncated to 'leve', which
makes the macro unusable.

MFC r355842: kbd: const'ify a couple of keyboard_driver fields

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Introduce KB_POLLED flag to struct keyboard's kb_flags field.

Remove explicit calls to keyboard methods with their respective variants
implemented with macros. This patch improves code readability. Reasoning
behind kbdd_* is a "keyboard discipline".

List of macros is supposed to be complete--all methods of keyboard_switch
should have their respective macros from now on.

Functionally, this code should be no-op. My intention is to leave current
behaviour of code as is.

kbdmux(4) keyboard multiplexer integration

o Add two new ioctl's KBADDKBD and KBRELKBD. These are used to add and remove
keyboard to (and from) kbdmux(4) keyboard multiplexer;

o Introduce new kbd_find_keyboard2() function. It does exactly the same job
as kbd_find_keyboard() function except it allows to specify starting index.
This function can be used to iterate over keyboards array;

o Re-implement kbd_find_keyboard() as call to kbd_find_keyboard2() with starting
index of zero;

o Make sure syscons(4) passed KBADDKBD and KBRELKBD ioctl's onto currently
active keyboard.

These changes should not have any visible effect.

Bump __FreeBSD_version accordingly.

Fix dev_t handling to avoid needless makedev() call.

Fix typo; the meaning of the 3rd parameter to genkbd_keyaction() is

Return consistent key action codes at key press and release
events. Otherwise you would see unexpected results if shift or
locking keys are defined to give different actions depending
on other shift/locking keys' state.

Please keep the ukbd module and the kernel in sync, otherwise
the USB keyboard won't work after this change.

With this commit, I hereby pronounce gensetdefs past its use-by date.

Replace the a.out emulation of 'struct linker_set' with something
a little more flexible. <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set. They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>). Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated. This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.

This is also the appropriate fix for exo-tree sources.

Put warnings in <machine/console.h> to discourage use.

Back out the previous change to the queue(3) interface.
It was not discussed and should probably not happen.

Change the way that the queue(3) structures are declared; don't assume that
the type argument to *_HEAD and *_ENTRY is a struct.

Rework shifta/ctla/alta key handling. It appears that there was
misunderstanding between the PR originator and me. I hope I got it
right this time.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.

- Add a module event function to the ukbd driver and make the ukbd KLD
module work.
- Delete unnecessary #include.

Add support new keys: lshifta, rshifta, lctrla, rctrla, lalta, and
ralta. These keys combine shift/ctrl/alt function and the AltLock
function. When these keys pressed together with another key, they act
just like the ordinary shift/ctrl/alt keys. When these keys are
pressed and released alone, Alt lock state is toggled.

- Remove cdevsw entry points in individual keyboard drivers;
instead, use generic entry points for all drivers.
- Eliminate bogus makedev().
- Eliminate softc in the lower drivers, as it is no longer necessary.

Keyboard driver update in preparation for the USB keyboard driver.

- Refined internal interface in keyboard drivers so that:
1. the side effect of device probe is kept minimal,
2. polling mode function is added,
3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
Set keyboard typematic rate. There has existed an ioctl command,
KDSETRAD, for the same purpose. However, KDSETRAD is dependent on
the AT keyboard. KDSETREPEAT provides more generic interface.
KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
ATKBD_DFLT_KEYMAP
Specify a keymap to be used as the default, built-in keymap.
(There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
These options are now gone for good. The new option is more general.)

KBD_DISABLE_KEYMAP_LOADING
Don't allow the user to change the keymap.
