This leads to the revert of r355806; this reduces duplication in keyboard
registration and driver switch lookup and leaves us with one authoritative
source for currently registered drivers. The reduced duplication later is
nice as we have more procedure involved in keyboard setup.
keyboard_driver->flags is used to more quickly detect bogus adds/removes.
From KPI consumers' perspective, nothing changes- kbd_add_driver of an
already-registered driver will succeed, and a single kbd_delete_driver will
later remove it as expected. In contrast to historical behavior,
kbd_delete_driver on a driver registered via linker set will now actually
de-register the driver so that it may not be used -- e.g. if kbdmux's
MOD_LOAD handler fails somewhere.
Detection for already-registered drivers in kbd_add_driver has improved, as
the previous SLIST_NEXT(driver) != NULL check would not have caught a driver
that's at the tail end.
kbdinit is now called from cninit() rather than via SYSINIT so that keyboard
drivers are available as early as console drivers. This is particularly
important as cnprobe will, in both syscons and vt, attempt to do any early
configuration of keyboard drivers built-in (see: kbd_configure).

Nothing modifies these things, but const'ify out of an abundance of caution.
If we could const'ify the definition in each keyboard driver, I likely
would- improper mutations here can lead to misbehavior or slightly more
annoying to debug state.
The previous implementation relied on a kbdsw array that mirrored the global
keyboards array. This is fine, but also requires extra locking consideration
when accessing to ensure that it's not being resized as new keyboards are
added.
The extra pointer costs little in a struct that there are relatively few of
on any given system, and simplifies locking requirements ever-so-slightly as
we only need to consider the locking requirements of whichever method is
being invoked.
__FreeBSD_version is bumped as any kbd modules will need rebuilt following
this change.
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.
This #ifdef is misleading as there are actually no user-serviceable parts
inside and, as far as I can tell, there is no pollution leading from
userland to this header. Furthermore, it becomes a slight nuisance when
attempting to move things around in this header.
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.

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.
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.

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.

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.

- 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.
