Zhenhua WANG f2804e5985 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.

Andreas Gampe a6ac9ce98b LibNativeBridge: Version 2
Add a callback function to retrieve "signal handler" from the bridge,
if the bridge wants it to be managed by the runtime. The signal handler
will be invoked after the runtime's own one, and before any other
chained handler.

Add a callback function to check compatibility of the bridge with the
library.

Add a function to expose the native bridge version. Add a test for this
function.
