avfilter: Dont partially merge lists

This prevents the unneeded insertion of multiple aresample filters in some cases

avcodec/utils: Warn the user about the lack of a lock manager if insufficient locks are detected

A lock manager is not the only possibility to avoid open/close locking
issues but its easier and more robust than maintaining a lot of lock/unlock
calls.
