opencv

legacy/compat.hpp no longer exist

* ball-finder auball and auballkl (a better version) is lacking functional content - commented out
* aucroprow is removed frol compile list (same cvFitEllipse(...) problem and maybe more
* auimgseg is removed - depend on opencv cv::ocl::oclMat - probably an early version of cv3::Mat
* aupipi is removed - depend on old cv code - old function anyhow
* aurosebot is removed - missing some opencv defines CV_RGB - and maybe more

* and there is more ....

G-streamer

* In urob4 streaming of images in and out - via UImgPush - has been removed - was not totally debugged anyhow. No rework needed I suppose.
* auv4lgst is a problem - should be reworked.
* auv4lgst is removed - depend on old gstreamer version 0.1

SmartMat

* seems to work - not tested. Except test program, that uses more funky methods. May give problems later.

BOOST

* no problem found yet.
