Bug#17667: An attacker has the opportunity to bypass query logging.

This adds a new, local-only printf format specifier to our *printf functions
that allows us to print known-size buffers that must not be interpreted as 
NUL-terminated "strings."

It uses this format-specifier to print to the log, thus fixing this 
problem.
