Asynchronous handling of log events

Coroutines provide a simple way to asynchronously handle log events, including dispatching them to different sinks.

Klogging launches new coroutines that are used in a number of places:

• For dispatching log events to sinks.
• For receiving log events from event and sink channels.
• For sending batches of log events to network destinations.

In addition, Klogging uses coroutine channels to process events.

• Log events are sent into the events channel in a coroutine.

• They are read in a different coroutine and dispatched to each matching sink by sending it into each sink.

• Events are read from sink channels in batches in different coroutines.
