grabber api and feature unification (#462)

Browse Source 
* move setvideomode to common place

* implement more croping and 3d support

* more api unification

* more refactoring

* osx fix

* next step

* add a mock for osx grabber. Now it is possible to test compile on none osx platforms.

* more unifications ...

* remove obsolete includes and grabbers are not dyn allocated. dispmanx needs rework an probaly not work atm

* first version of dispmanx mock. it compiles, but outputs a black image

* now dispmanx mock works!

* activate mocks in travis linux build
prepare dispmanx to rgb image out

* dispmanx now with image rgb output
fix deadlock with w/h -1 in grabber v4l
cleanups

* fix json

* fix some runtime stuff

* Update FramebufferWrapper.cpp

fix missing code

* unify grabframe

* 3d and croping for amlogic

* fix setimage not working

* make use of templates
save some codelines

* save more code lines
