AVRecord2 Code

AVRTuner is displaying video using SDL now. So kdetvview was removed.
Vidstream, Sndstream, Recorder and AVRTuner are working properly now.
AviFile does not. Yet.

Conversion is done. Now v4l2 and libconfig are used through all the apps. Code is compilable... yet still not working.
Bug hunt! =^_^=

AVConfig class was improved.
Vidstream, Sndstream and AviFile classes are now compilable.
main.cpp of avrecord was rewritten slightly and uses now libconfig and AVConfig.

Vidstream, Sndstream, AviFile and BaseRecorder were rewritten somewhat to use libconfig.
Thus old ConfigFile is deleted from the project.
And new AVConfig is added: a wrapper for libconfig::Config which also can query v4l2 device to initialize configuration and fill missing controls, inputs and standarts.

Old .conf files are deleted.
In avfile the libconfig api is used now.
Video frames are encoded now in the same pixel format they were captured. No need to fill AVFrame by hand now, and it's possible to use all any planar pixel format common for v4l2 and ffmpeg.
Framerate is now determined by the v4l2 standard. No more setting or estimation needed.

Vidstream is now switched to V4L2 and libconfig apis, though nothing is tested yet: the project is not compilable obviously.

All calls of configuration methods now enclosed in a try-catch handlers.
Default config is used now as a template for initialization of the real config and thus is called properly -- cfg.template

ChangeLog updated.
