Summary

This version notably brings:

• Application Security Monitoring on linux/arm64 and darwin/arm64
• The profiler now captures its own CPU overhead. Previously, CPU profiling could be stopped before follow-on work processing the other profile types completed. There is now proper synchronization so this work is captured. Note that there may be a small (<1%) increase in CPU time on profiles. This is not new overhead, or a regression. It is just work that was already being done, now more accurately reflected.
• The new ddtrace.UseLogger function can be used to configure logging for both the tracer and profiler.

A couple of improvements and fixes can also be found in the list of changes below.
