Felix Lange fd9b03a431 ethlog: fix concurrency
Rather than spawning a new goroutine for each message,
run each log system in a dedicated goroutine.

Ensure that logging is still asynchronous by using a per-system buffer
(currently 500 messages). If it overflows all logging will hang,
but that's better than spawning indefinitely many goroutines.
