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.

evdev: Disable value normalization and state filtering for SND events.

Some events can take sound pitch as a value so can not be represented
as binary on/off events. Tracking for on/off state is left in place
as it is a part of the evdev API.

[evdev] Adds evdev support to sysmouse(4) driver

For horizontal (T-axis) wheel reporting which is not supported by
sysmouse protocol kern.evdev.sysmouse_t_axis sysctl is introduced.
It can take following values:

0 - no T-axis events (default)
1 - T-axis events are originated in ums(4) driver.
2 - T-axis events are originated in psm(4) driver.

Allow using of driver's mutex instead internal one for evdev locking.

Add new API call: evdev_register_mtx which takes lock argument that
should be used instead of internal one for evdev locking. Useful for
cases if evdev_push_event() is always called with driver's lock taken
and reduces amount of lock aquisitions. This allows to avoid LOR
between ev_open/ev_close invocations and evdev_push_event() Such LOR
can happen when ev_open/ev_close methods acquire driver lock and
evdev_push_event() is called with this lock taken.

Add evdev protocol implementation

evdev is a generic input event interface compatible with Linux
evdev API at ioctl level. It allows using unmodified (apart from
header name) input evdev drivers in Xorg, Wayland, Qt.

This commit has only generic kernel API. evdev support for individual
hardware drivers like ukbd, ums, atkbd, etc. will be committed later.

Project was started by Jakub Klama as part of GSoC 2014. Jakub's
evdev implementation was later used as a base, updated and finished
by Vladimir Kondratiev.
