Change the signature of sqfs_compressor_create to return an error code
Make sure the function has a way of telling the caller *why* it failed. This way, the function can convey whether it had an internal error, an allocation failure, whether the arguments are totaly nonsensical, or simply that the compressor *or specific configuration* is not supported.
