This patch closes ticket #1886.

I've rethought the approach and found a much cleaner way. 
We now split handling of command line arguments into two parts.
Only the critical part of getting the config file is done first (and -v as it prevents startup).
The rest (currently only -b) is deferred.

This achieves the important bit why #1886 was created. 
It allows us to log error messages to stderr even if the -b argument is passed.
This is mainly for the case where the logfile or TCP port can't be opened.
