NEWT: Adding support for BCM VC IV (Broadcom VideoCodec 4) and Linux console mouse tracker

Rasperry PI uses the 'BCM VC IV' GPU via console as it's default configuration.
This driver enables direct support for JOGL/NEWT.

Due to the lack of detection (TODO) users have to specify the Java property:
  -Dnativewindow.ws.name=jogamp.newt.driver.bcm.vc.iv

- Autodetection should be included in 'NativeWindowFactory._getNativeWindowingType()'
  while adding a new TYPE: 'TYPE_BCM_VC_IV'.

- Autodetection may need to detect whether an X11 Display runs and the installed
  EGL library uses it (instead of the default console one)
