Merge 208554 from head:

  Add uep(4), driver for USB onscreen touch panel from eGalax.

  The driver is stub. It just creates device entry and feeds
  reassembled packets from hardware into it.

  If in future we would port wsmouse(4) from NetBSD, or make
  sysmouse(4) to support absolute motion events, then the driver
  can be extended to act as system mouse. Meanwhile, it just
  presents a /dev/uep0, that can be utilized by X driver, that
  I am going to commit to ports tree soon.

  The name for the driver is chosen to be the same as in NetBSD,
  however, due to different USB stacks this driver isn't a port.

The driver is supported by ports/x11-drivers/xf86-input-egalax.

+.Sh BUGS
+.Nm
+can't act like
+.Xr sysmouse 4 ,
+since the latter does not support absolute motion events.
+.Sh FILES
