8282515: More clean up on NativeLibraries just for JNI library use

[mlchung]

This patch further cleans up NativeLibraries just for JNI library use. RawNativeLibraries implements its own native load and unload methods. In addition, this also fixes the implementation of RawNativeLibraries::load not to throw UnsatisfiedLinkError if a library cannot be loaded for any reason but instead returns null.

Looks good - thanks for cleaning up further. I think separating the library implementation makes a lot of sense. There's some duplication at the native level, but that's acceptable IMHO - and probably better than having a shared piece of logic that can work in two very different modes.

Thanks for the review.

I also think this is better and cleaner separation. The duplicated native code is small and they just call JVM_LoadLibrary and JVM_UnloadLibrary that makes it very clear what this native method does.
