Bug 1134 - Fix ProcAddressEmitter.getFunctionPointerTypedefName() ; Fix JavaEmitter's Function/Struct Emission

Fix ProcAddressEmitter.getFunctionPointerTypedefName():
  - needs to produce function-pointer-type name w/ original name

Fix JavaEmitter's Function/Struct Emission:
  - needs to create FunctionSymbol w/ original native name,
  - then rename - preserving the original one.
