Bug 1363: Java 11: Recognize Java9+ ..; Support JEP 178 static linkage libgluegen-rt[.so] -> libgluegen_rt[.so|.a]

Recognize Java9+ ..

- Recognize new Java9+ version string as of JEP 223

- Avoid Classpath's private findLibrary call

+++

Support JEP 178 static linkage (OpenJDK 1.8)

- Need to change native library basename: libgluegen-rt[.so] -> libgluegen_rt[.so|.a]
  since the dash '-' is not supported in a ANSI-c function name.

- Added 'JNI_OnLoad_gluegen_rt' to recognize statical linked JNI code

- Added JNI_VERSION_1_8 to jni/jni.h
