C11 and atomic detection

Preprocessor HAVE_ATOMIC macro is added if the compiler supports C11.

Tracing

Debugging can be hard, especially when it comes to time-critical functions. Libre has now a API for tracing with minimal overheads and produces a json file (supported by several tracing tools like chrome://tracing, https://ui.perfetto.dev/...).

Example usage: https://github.com/baresip/retest/blob/master/src/trace.c#L28-L55
