* Put curly braces on a line of their own
* Use INT16_MAX and INT16_MIN instead of magic numbers
* Make some global vars statically linked and const (since they're constants for the adpcm audio codec only)
* Make some functions in rpl_reader statically linked (they're only used in that file)
* Add include file dec130.h instead of forward declaring functions in source files
