* Add diagnostics module in OpenThread
- provide the same diagnostics interface for both CLI and NCP usage
- implement common diagnostics features based on existing platform interface defined in 'include/platform/'
- other more platform specific diagnostics features will be processed under platform layer
- update CLI interface to support diagnostics feature
- update both Posix and CC2538 platform to support diagnostics feature
* Add diagnostics module unit test
- move platform.h from "examples/platform" to "include/platform"
- add test_diag.cpp to test diagnostics module
* Add a configuration option that would enable/disable diagnostics module
Add --enable-diag configuration option to enable/disable diagnostics module when building OpenThread.
* Added initial unit tests for 6LoWPAN layer decompression. Extended unit test framework with helper functions for setting up ASCI hex test vectors.
* Added missing license headers. Cleanly broke C++ into .hpp vs .h.
* Added multicast test vectors to 6lo decompression unit tests.
* Make pretty.
* Added Lowpan::Compress unit test.
* Allow extended initializer lists for unit test build.
* Split out sTestVectorLowpan into pure C99 file as it uses struct { .mField = initializers; } which may upset stricter C++ compilers such as clang++.
* Fix make distcheck - add stubs to test_lowpan for unhandled driver callbacks.
* Resolve most comments besides otDump suggestion.
