PlayoutFrequency(), at least, is called ~200 times a second. The others
appear to not be in practice, but it's unclear what value they serve.
They were traces before https://chromium-review.googlesource.com/c/518133/,
which was more reasonable, as you could enable them for just audio
coding traces. But now that they are just logs, they make all VERBOSE
logging unusable.
