* Make <sys/sysref2.h> a kernel only header.
* Remove sys/types.h includes that follow <sys/param.h> in devfs(5).
* Add sys/malloc.h includes where it is actually used in sources.

While there, minor whitespace cleanup.

atmel_mxt - Issue RESET in Acer C720P touch-screen driver

* Sometimes the hardware appears to lose it, resulting in non-deterministic
reporting of phantom fixed coordinate presses and movement which messes
up X's pointer position. This problem can survive a reboot.

* Issue a RESET command to the chipset on attach. This will clear up
any issues that would otherwise survive reboot.

* Add a sysctl, setting debug.atmel_mxt_reset=1 will cause the chipset
to be reset. If the chipset goes nuts on a live system, issuing this
sysctl should clear it up.

Detection of the situation not yet in place, so for now this sysctl must
be issued manually if the problem occurs.

atmel - Add automatic recalibration

* Add automatic recalibration every 30 seconds when idle. I'm really not
sure if this is necessary or not but for now we do it.

* Interval can be adjusted with sysctl debug.atmel_mxt_autocalibrate,
set to 0 to disable.

atmel_mxt - Add atmel MXT touchscreen driver (Acer c720p)

* Implements the communications infrastructure on the hardware backend and
emulates an elographics tablet on the frontend.

* X Configuration is:

Section "InputDevice"
Identifier "TouchScreen0"
Driver "elographics"
Option "Device" "/dev/atmel1-4a"
# Option "ZAxisMapping" "4 5 6 7"
EndSection

* System configuration is (in /boot/loader.conf):

ig4_load="YES"
atmel_mxt_load="YES"

* Currently only tested and only likely to work with the Acer c720p.
Can do basic touchscreen operations... hold-move-and-release for
button-1. Can move or resize windows (you may want to make your resize
widgets bigger). Can hit buttons and hotlinks in browsers. Cannot
scroll a browser window on its own.

* Noise issues. I've noticed that both my chromebooks have a lot of mouse
pointer jitter with both the trackpad and the touchscreen, more than
I can actually fix. I've noticed some complaints on the linux forums too
so it aint just us.

The jitter is reduced if you put the laptop on your lap, and appears to
go away entirely if the laptop is on your lap AND the power is disconnected
(i.e. running on battery).
