The echoaudio locally defines TRUE and FALSE. Not only is this redundant given that C now has a boolean type it results in lots of warnings as other headers also define these macros, causing duplicate definitions. Fix this by removing the local defines and converting all local users to use the standard C true and false instead, simply removing the macros is less safe due to implicit inclusion of the other definitons.
