New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.
added docs and tests for mqtt library, small fixes (removed warnings, option for custom outbox, websocket bug fixed for longer transports). refactored to use common tcp_transport component, support for CMake build system.
Closes#2108
Run some unit test cases based (poorly) around sodium's test infrastructure.
Increase in unity test task stack is due to signature tests, load a lot of data onto the stack.
This change adds gitlab CI support. It tests if latest master of esp-idf-template can be built with the commit of ESP-IDF in question. Currently it's a bit lax because both SDK_PATH and IDF_PATH are defined.
This change also changes components/esp32/lib submodule to point to Github over HTTPS instead of SSH, because CI server might not have its SSH keys uploaded to Github.
