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.

Felix Lange c090a77f1c ethlog: simplify LogSystem interface 
Messages are formatted by generic part, so the log system doesn't need
to provide formatting. This fixes the test from the previous commit.

As a small bonus, log systems now have access to the level of
the message. This could be used to provide colored logging in the
future.

Felix Lange 50f5ba5b0c ethlog: add test for '%' in log message 
This test fails because the log message is formatted twice.

Felix Lange ec132749aa ethlog: improve TestLogSystem 
It's now safe for concurrent access.
Output checking looks better.

zelig d4300c406c logger fix 
- introduce quit, drained, shutdown channels
- mainLoop falls through reading message channel to drained state, and waits is blocked in default branch until any message is sent
- Flush() waits for <-drained
- Stop() pushes quit and nodges mainloop out of blocking drained state
- package-global mutex
- Reset()
- clear tests

zelig 8e9cc36979 refactor logging. Details: 
- packages use tagged logger sending log messages to shared (process-wide) logging engine
- log writers (interface ethlog.LogSystem) can be added to the logging engine by wrappers/guis/clients
- shared logging engine dispatching to multiple log systems
- log level can be set separately per log system
- async logging thread: logging IO does not block main thread
- log messages are synchronously stringified to avoid incorrectly logging of changed states
- README.md
- loggers_test
