* The debug macros are used if you compile with DEBUG defined.
*
* Usage:
*
* DEBUG_puts("string")
* DEBUG_printf(("format string", arg, arg, ...));
*
* Note the extra parenthesis around the DEBUG_printf macro...
*
* Newlines are not required on the end of messages, as both add one when
* writing the output.
*
* If the first character is a digit, then it represents the "log level" of the
* message from 0 to 9. The default level is 1. The following defines the
* current levels we use:
*
* 0 = public APIs, other than value accessor functions
* 1 = return values for public APIs
* 2 = public value accessor APIs, progress for public APIs
* 3 = return values for value accessor APIs
* 4 = private APIs, progress for value accessor APIs
* 5 = return values for private APIs
* 6 = progress for private APIs
* 7 = static functions
* 8 = return values for static functions
* 9 = progress for static functions
