Logging utilities

General Description

A logging subsystem that allows run time control for the logging level.

Log messages are passed back to the application for output. Log messages are given sequence numbers. A time callback can be provided by the application for the timestamp for each output line. Log messages are mutex protected across threads so that log messages do not interrupt each other.
