* Timers now are Application thread safe
* Timers now have consistent API independend of Application (no more c style timers)
* Timers can have either: callback or override onTimer() method - this
way we can create more complicated timers or just use existing ones
* gui::Timer added via adapter class GuiTimer to decouple sys::Timer
with gui::Timer
* Fixed race in wrapper
* Updated docs
* fixed using std and cpp_freertos and DataReceivedHandler hidden in Application.hpp
Add proper catch2 support:
- add catch2 as a submodule
- add cmake function to add test easily
- discover each test in test binary
- remove copies of catch.hpp
- do not try to process tests for rt1051
Do not test internals of utf8, only public interface (nasty bugs could
occur otherwise).
