Sanitize command strings before logging them.

Normally bitcoin core does not display any network originated strings without
 sanitizing or hex encoding.  This wasn't done for strcommand in many places.

This could be used to play havoc with a terminal displaying the logs,
 especially with printtoconsole in use.

Thanks to Evil-Knievel for reporting this issue.
