java: Updated gpio.c to use JNI functions set in mraa_lang_func

Browse Source 
This is a re-design of commit 0041801. mraa_lang_func_t structure has been
added (similar in design to mraa_adv_func_t) that points to JNI functions
implemented in src/java/mraajni.c. Functions are set by libmraajava.so,
see wrapper entry in src/java/mraajava.i. As gpio.c now uses these
functions, language specific #ifdef code has been removed as JNI code
is only called if functions are defined (i.e. not NULL)
