[log] Consistently escape log entries

Browse Source 
Implicitly escape all output that is passed to Log::MessageBuilder.
We escape non-printable characters and the log field separator ','
using the \x00 and \u0000 escape sequences.

Example:
Before: event-foo,"space: ","comma: ,","double quotes: """
After:  event-foo,space: ,comma: \x2C,double quotes: "

This might slightly impact human readability of the log files in
extreme cases. However, most strings do not contain any escaped
characters.
