Prefix all SPL debug macros with 'S' 

To avoid conflicts with symbols defined by dependent packages
all debugging symbols have been prefixed with a 'S' for SPL.
Any dependent package needing to integrate with the SPL debug
should include the spl-debug.h header and use the 'S' prefixed
macros.  They must also build with DEBUG defined.

* CDEBUG() - Log debug message with specified mask.
* CDEBUG_LIMIT() - Log just 1 debug message with specified mask.
* CWARN() - Log a warning message.
* CERROR() - Log an error message.
* CEMERG() - Log an emergency error message.
* CONSOLE() - Log a generic message to the console.
* SDEBUG() - Log debug message with specified mask.
* SDEBUG_LIMIT() - Log just 1 debug message with specified mask.
* SWARN() - Log a warning message.
* SERROR() - Log an error message.
* SEMERG() - Log an emergency error message.
* SCONSOLE() - Log a generic message to the console.
*
* ENTRY - Log entry point to a function.
* EXIT - Log exit point from a function.
* RETURN(x) - Log return from a function.
* GOTO(x, y) - Log goto within a function.
