- `omnitrace-sample` executable which executes sampling (no instrumentation) - fixes bug with OMPT ignoring value of `OMNITRACE_USE_OMPT` - fixes some issues with sampling duration - new `OMNITRACE_SAMPLING_INCLUDE_INLINES` configuration variable - restricts process-sampling to 100 interrupts/sec when inheriting value from `OMNITRACE_SAMPLING_FREQ` - `OMNITRACE_PROCESS_SAMPLING_FREQ` still supports up to 1000 interrupts/sec - fixes bug with colorized log not truly being disabled in all instances - adds tests for `omnitrace-sample` - adds tests for sampling duration - settings ROCP_TOOL_LIB to libomnitrace-dl throws error - rocprofiler does not configure correctly when this is done - Quiet numa_gotcha warnings - Fixed some shadowed variables
