Implement Camera Multiplexing API * IdideoCapture + two wrong function function waitAny Add errors catcher Stub for Python added. Sifting warnings One test added Two tests for camera and Perf tests added * Perf sync and async tests for waitAny() added, waitAnyInterior() deleted, getDeviceHandle() deleted * Variable OPENCV_TEST_CAMERA_LIST added * Without fps set * ASSERT_FAILED for environment variable * Perf tests is DISABLED_ * --Trailing whitespace * Return false from cap.cpp deleted * Two functions deleted from interface, +range for, +environment variable in test_camera * Space deleted * printf deleted, perror added * CV_WRAP deleted, cv2 cleared from stubs * -- space * default timeout added * @param changed * place of waitAny changed * --whitespace * ++function description * function description changed * revert unused changes * videoio: rework API for VideoCapture::waitAny()
