Seems the strong otPlatOtnsStatus is not used, but the weak
otPlatOtnsStatus was used in the original code if built by cmake.
This commit fixes this issue. Now both cmake and make builds
correctly.
This commit is to support OTNS by:
- raising the max number of simulating nodes to 999 if OTNS=1
- implementing the status-push mechanism
To build:
$ make -f examples/Makefile-simulation OTNS=1
This commit should have no change of OpenThread behaviors on platforms
except simulation.
