It also has the assumption that there's at least one media device to make a camera work. Now that the assumption will be broken by the virtual pipeline handler added in the following patches, and developers should be aware of the available functions in the base class to handle media devices, the Fatal check is no longer needed.

Implement two types of test patterns: color bars and diagonal lines generator and use them in the Virtual pipeline handler. A shifting mechanism is enabled. For each frame, the image is shifted to the left by 1 pixel. It drops FPS though. Add a dependency for libyuv to the build system to generate images in NV12 format from the test pattern.

The config file is written in yaml, and the format is documented in `README.md`. The config file will define the camera with IDs, supported formats and image sources, etc. In the default config file, only Test Patterns are used. Developers can use real images loading if desired.
