This splits out the core CoglPipelineLayer support code from cogl-pipeline.c into cogl-pipeline-layer.c; it splits out the debugging code for dumping a pipeline to a .dot file into cogl-pipeline-debug.c and it splits the CoglPipelineNode support which is shared between CoglPipeline and CoglPipelineLayer into cogl-node.c. Note: cogl-pipeline-layer.c only contains the layer code directly relating to CoglPipelineLayer objects; it does not contain any _cogl_pipeline API relating to how CoglPipeline tracks and manipulates layers.
