fix issue 305: CodeConverter.replaceArrayAccess leads to java.util.ConcurrentModificationException

Fix a race condition in CtClassType#getClassFile3

This fixes Issue #350.
Check for extended frame type when updating StackMapTable offset.

javassist fails to find a class when concurrently running process
compresses the class (converts classfile to raw bytes)

the idea of the fix is to make sure to only update rawClassfile and classfile
under lock in getClassFile3, all other places that modify classfile are
already synchronized

when reading the object state, we need to read under lock both classfile and
rawClassFile otherwise we might get an inconsistent state

add functions for getting the parameter names of method

Fixes #350
