There's no need, since configure_file writes its output using native
line endings, anyway.

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.

Also, added the missing include guard to perf_precomp.hpp.

with Visual C++, a dummy .cpp is created at build time.

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)

This allows us to forget about the GTEST_(CREATE|LINKED_AS)_SHARED_LIBRARY
macros and to get rid of the dependency on cvconfig.h.
