VideoWriter memory leak solved.

Android 4.3 support added;
ANY camera index support fixed;
applyProperties now uses camera->reconnect() instead close/connect for Android 4.x.

It's part of CMake nowadays, too.

In fact, I don't think we actually use it... but I kept the include,
just in case.

ReST directive was used. Also fixed some other ReST directives that were
not correct and removed some warnings during buildbot checks.

disabled 64f IPP DFT; added IPP Gaussian filter; added IPP GetRectSubPix; added IPP BilateralFilter (temporarily disabled)
