the following improvements to linux-fbdev:

1. updated makefiles to build libOSMesa as well as libGL

these are improvements to fbdev-glut
1. mouse cursor will timeout and be invisible if not being used
2. do not restore colormaps to truecolor targets, this causes problems at
   exit on my g450
3. fixed a crash when cleaning up from failure by munmaping what had not
   yet been mmaped
4. Resize event handling is improved, the resize function is not invoked
   from a signal handler now.
5. The main loop can detect if it is running very fast (greater than 2khz)
6. keyboard up and special up events are generated from stdin input mode
   and if it is also not redrawing, it sleeps
7. corrections in escape sequences for function keys for stdin input
