MFC r343339: Silence Clang Scan warning about use of unitialized variable.

The logic is changed to depend on actual "beep" parameters instead of on a
flag that may be set for invalid parameters.

An embedded literal escape character has been replaced by "\e", since it
could confuse terminals when displaying the affected line.

MFC r326276:

various: general 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.

No functional change intended.

Convert usr.sbin to LIBADD
Reduce overlinking

Update man-pages to correctly refer to changed pathes and naming conventions
for systems with vt(4) consoles.

MFC after: 3 days

Remove band.aid that made kbdcontrol lookup keymap files in the syscons
path even under vt, which is no longer useful, since the syscons keymap
files have been converted and committed for use by vt.

The previous commit (r269119) introduced a regression: It removed the
ability to specify the the full path name of the keymap file.

Instead leave the original search order intact, but insert the path for
newcons-specific fonts (if run on a system using newcons):

- KEYMAP_PATH in environment
- full path name
- /usr/share/vt/keymaps (only if newcons is in use!)
- /usr/share/syscons/keymaps (also as fall-back for newcons)

MFC after: 1 week

Fix obvious off by one error: prefix[1] should be set to the path of the
newcons specific keymap files, not prefix[2]. The result of this bug was
that kbdcontrol ignored the files in the syscons keymap directory, which
apparently still work under newcons, for most locales.

Make the keyboard layer Unicode aware.

Just take keyent_t to use an u_int to store the Unicode codepoints.
Unfortunately the keymap is now too big to be loaded using an ioctl
argument, so change the ioctl to pick a pointer.

This change breaks kbdcontrol ABI. It doesn't break X11, because X11
doesn't do anything with syscons keymaps. It just switches the device
out of K_XLATE.

Unhardcode 0x100 inside kbdcontrol.

In preparation for Unicode support for the keyboard layer, we'd better
get rid of all the hardcoded 0x100/0xff constants in kbdcontrol.
Instead, add a flag called SPECIAL stored in the top bit of the integer.

Adding Unicode support is very simple now; just change u_char map[] to
u_int map[] in keyent_t, change the bounds checking in kbdcontrol to
0x1FFFFF and modify the ioctls to allow loading these new keymaps.

kbdmux(4) keyboard multiplexer integration

o Slightly change KBADDKBD and KBRELKBD ioctl() interface. Instead of passing
keyboard index pass keyboard_info_t structure with populated 'kb_unit' and
'kb_name' fields. Keyboard index is not very user-friendly and is not very
easy to obtain. Keyboard driver name and unit, on the other hand, is much
more user friendly and known almost all the time;

o Move definition of keyboard_info_t structure up;

o Teach kbdcontrol(1) how to attach/detach keyboards to/from the keyboard
multiplexor;

o Update kbdcontrol(1) man page and document new functionality.

To attach/detach keyboard to/from keyboard multiplexor one needs to use
keyboard device name (i.e. ukbd0).

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.
