Upgrade native bridge to version 3 to support namespace

Native bridge implements namespace related interfaces in version 3.
The namespace semantic here is same as Android dynamic linker's.
Native loader wraps library loading functions of dynamic linker and
native bridge. Thus, Android runtime is able to load native library
of different ISA on one device by calling native loader directly.
