fragend-arbfp: Move the pipeline cache to a separate file The pipeline cache is now handled in CoglPipelineCache instead of directly in the ARBfp fragend. The flags needed to hash a pipeline should be exactly the same for the ARBfp and GLSL fragends so it's convenient to share the code. The hash table now stores the actual pipeline as the value instead of the private data so that the two fragends can attach their data to it. That way it's possible to use the same pipeline key with ancestors that are using different fragends. The hash table is created with g_hash_table_new_full to set a destructor for the key and value and there is a destructor for CoglPipelineCache that gets called when the CoglContext is destroyed. That way we no longer leak the pipelines and shader state when the context is desroyed.

pipeline-cache: Prune old unused pipelines when the cache gets too big Previously when a pipeline is added to the cache it would never be removed. If the application is generating a lot of unique pipelines this can end up effectively leaking a large number of resources including the GL program objects. Arguably this isn't really a problem because if the application is generating that many unique pipelines then it is doing something wrong anyway. It also implies that it will be recompiling shaders very often so the cache leaking will likely be the least of the problems. This patch makes it keep track of which pipelines in the cache are in use. The cache now returns a struct representing the entry instead of directly returning the pipeline. This entry contains a usage counter which the pipeline backends can use to mark when there is a pipeline alive that is using the cache entry. When the hash table decides that it's a good time to prune some entries, it will make a list of all of the pipelines that are not in use and then remove the least recently used half of the pipelines. That way it is less likely to remove pipelines that the application is actually regenerating often even if they aren't in use all of the time. When the cache is pruned the hash table makes a note of how small the cache could be if it removed all of the unused pipelines. The hash table starts pruning when there are more entries than twice this minimum expected size. The idea is that if that case it hit then the hash table is more than half full of useless pipelines so the application is generating lots of redundant pipelines and it is a good time to remove them.
