Found Native methods with no matching symbols

[rupeshkoushik07]

I have done bytecode analysis for JFFI and found that there are native methods which donot have any symbols present in any of the libraries

Example (Foreign.java declares native but the symbol is not exported by
either jffi-1.2 or jffi-1.3.11 in this repo):

com.kenai.jffi.Foreign.newNativeMethod
com.kenai.jffi.Foreign.freeNativeMethod
com.kenai.jffi.Foreign.compileNativeMethods
com.kenai.jffi.Foreign.freeCompiledMethods
com.kenai.jffi.Foreign.registerNativeMethods
com.kenai.jffi.Foreign.unregisterNativeMethods
com.kenai.jffi.Foreign.invokeArrayWithObjectsReturnObject

The native declarations exist in Foreign.class but the C implementations are gated on a build flag that is off in every Linux build shipped via JNR-FFI/JNA.

Hi @headius ! Regarding #191 , I'm weighing two options and wanted to check your preference:

• Option A: Complete the native side. Better for compatibility/ABI stability, but adds some maintenance overhead for older paths.

• Option B: Remove unused Java-side declarations. Cleaner and gets rid of dead code, but carries a risk of breaking downstream runtime compatibility.

I’m leaning towards A since jffi is so low-level, but let me know if you’d rather just prune the dead code!
