Added isXXXEnabled for logging statements

Browse Source 
Guarded the logging statements which do concatenation of strings
or calling toString on objects. When a log level isn't enabled
this still would produce garbage that would need to be collected.

Guarded all logging up to info, warn and error can be assumed to be
enabled on a production system.
