ATS performance degradation when debug output is enabled

Since this was mentioned during the summit, I just wanted to highlight that
there was an issue opened for this, I created a PR, but it was never
merged:  https://github.com/apache/trafficserver/issues/6150

Note also that the PR included an implementation of read/write locking that
avoids writer starvation, which apparently is an issue with
std::shared_mutex and pthreads rwlock.
