Motivation:

Swift does not currently generic specialize static methods on final classes that have no parent classes when the method is implemented in a protocol. This means that calling such methods through Self will not involve a generic specialization, whereas using the explicit type name will.

This pattern manifests in the [un]wrap{In}{Out}bound{In}{Out} static methods defined in the ChannelInboundHandler and ChannelOutboundHandler protocols and their use from all channel handler classes. As such, we should replace the Self part in all Self.[un]wrap{In}{Out}bound{In}{Out} calls with the explicit class name.

Modifications:

Replaced all Self.[un]wrap{In}{Out}bound{In}{Out} calls to use the explicit class name.

Result:

Eliminates unnecessary overhead.
