Changes

Remove unused addNativeJarLibs() method; the only consumer was a unit test
of the method.

Clean up native library loading and remove the ability to strip prefixes.

Bug: 1023
Bug: 1024

StringBuilder message parameter was unused.

Do not keep re-indexing into the same array.

gluegen: remove unused imports, unneeded semicolons, add missing @Override annotations

gluegen: remove the unused reverse map from TypeDictionary

gluegen: relax private variable access to package-private for members accessed from inner class

Otherwise the compiler has to fill in a wrapping access function for the inner
class to call, which is less efficient.

Remove @deprecated methods
