No functional change intended.

sys: Remove $FreeBSD$: two-line .h pattern

Remove /^\s*\*\n \*\s+\$FreeBSD\$$\n/

evdev: Make MT tracking IDs monotonically increasing sequence.

evdev: Remove useless "initial value" parameter from evdev_support_abs()

It can not be used for setting of state of multitouch events.
If necessary, use evdev_push_event() instead of it.

kqueue: save space by using only one func pointer for assertions

Merge ^/head r337646 through r338014.

Modularize evdev

- Convert "options EVDEV" to "device evdev" and "device uinput", add
modules for both new devices. They are isolated subsystems and do not
require any compile-time changes to general kernel subsytems
- For hybrid drivers that have evdev as an optional way to deliver input
events add option EVDEV_SUPPORT. Update all existing hybrid drivers
to use it instead of EVDEV
- Remove no-op DECLARE_MODULE in evdev, it's not required, MODULE_VERSION
is enough
- Add evdev module dependency to uinput
