Change function definitions using the identifier-list form used in the
1st edition of Kernighan and Ritchie's The C Programming Language, to
that of the parameter-type-list form described in the ANSI X3.159-1989
standard.

In ISO/IEC 9899:2023 drafts, there is only one form of function definition.
"N2432 Remove support for function definitions with identifier lists".

Use timeout_add_msec(9)

hz can simply be reduced has the code wants to wait
(period * hz) / 1000 [ticks] = period / 1000 [s] = period [ms].

With the zero check, this perfectly matches the millisecond version.

This conversion by itself also lifts the implicit expection of the period
to be evenly divisible by ten; in case it was not, integer division
would truncate it.

See /sys/wscons/wskbd.c for how the period is set up.

If you use sys/param.h, you don't need sys/types.h

Reduces the noise around the global ``ticks'' variable by renaming
all the local ones to ``nticks''.

Move HID support files out of dev/usb into new dev/hid directory

These files aren't USB-specific and were used by the previous
Bluetooth implementation, and will be used by the upcoming
HID-over-i2C implementation

Factorization of the bluetooth and usb hid input driver logic, to reduce code
duplication and divergence.
Thanks to mlarkin@ for bluetooth devices tests.

Finish the beep(4) driver by hooking it up to the ukbd(4) beep handler
and disable the one second long beep on attach.

ok miod@

implement frequency setting for the beep. It also beeps for one second
during boot (this is annoying, I know... I'll hook it up to the keyboard
handler later).

fetch the beep clock frequency (we'll need it to compute the audio frequency later)

placeholder driver for the bbc,beep device. should be straightforward
to fill in later.
