These changes both simplify the Java code and improve performance across the JNI boundary. This also fixes the AnalogCrossConnectTest by adding delays to setInterruptHigh() and setInterruptLow() to ensure the change in voltage has time to propagate and extends the timeouts in AbstractInterruptTest. Detailed changes: Hoisted status checks to C. This avoids the need to create direct byte buffers (expensive) and significantly simplifies the Java code. The C code now directly generates the exception or reports the error to the DS. The JVM pointer is now a global across the JNI, initialized by the OnLoad function, avoiding the need for some of the class-specific initializers to get this pointer for callbacks. Opaque pointers (such as ports) are now passed as long values rather than with a ByteBuffer wrapper. Added extern "C" to source files. This allows earlier detection of JNI definition mismatches to the Java source headers. Changed JNI signatures to more closely match HAL signatures (in particular, boolean is now universally used instead of byte for HAL bool, which cleans up mapping back and forth to 1/0 from true/false).
