util: check for compression engine availability before returning If a requested compression engine is registered but not available, requesting it will now abort. To be honest, I'm not sure if this is the appropriate mechanism for handling optional compression engines. I won't know until all uses of compression (bundles, wire protocol, revlogs, etc) are using the new API and zstd (our planned optional engine) is implemented. So this API could change.
