logging: use level-based logger functions

Do not pass logger objects around anymore. Shuffle some messages to make
them consistent with the new logging API. Avoid using %v when a more
specific verb exists for the argument types.

The loggers are completely disabled (i.e. Sprintf is not even called)
by default. They are only enabled when redirecting stdout to a file.
