For dynamic linking perspective, semantics of NativeBridge needs to
align with dynamic linker. This patch adds "linked namespace" semantic
which shares some libraries from one namespace to another.
Test: make test-art-host-run-test-115-native-bridge

An app should be able to make cross-arch calls to different apps
via other app's Context.getClassLoader()

Test: Boot fugu. Check that there are no linker-namespace
related errors in the log.

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.

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.

Also:
- add kPreInitiliazed state to native bridge with check transition:
kOpened->kPreInitialized->kInitialized
- made sure we free the memory for the code_cache_path
- tidy up some error messages
- tidy up tests
- add a dummy native bridge to test with

Do not allow arbitrary paths for the native bridge - only allow
simple names.
Do not allow re-setup of the native bridge.
