	The ConverterFactoryBase::create() function returns a nullptr when no converter is found. The only caller, SimpleCameraData::init(), checks if the converter is valid with isValid(), but doesn't check if the pointer is null, which can lead to a crash. We could check both pointer validity and converter validity in the caller, but to limit the complexity in callers, it is better to check the converter validity in the create() function and return a null pointer when no valid converter is found.

2022-12-14	libcamera: Declare generic converter interface	Xavier Roumegue
	Declare a converter Abstract Base Class intended to provide generic interfaces to hardware offering size and format conversion services on streams. This is mainly based on the public interfaces of the current converter class implementation found in the simple pipeline handler. The main change is the introduction of loadConfiguration() function which can be used by the concrete implementation to load hardware specific runtime parameters defined by the application.
