George Joseph has uploaded this change for review. ( https://gerrit.asterisk.org/c/asterisk/+/14631 )
Change subject: ACN: Add tracing to existing code

ACN: Add tracing to existing code
Prior to making any modifications to the pjsip infrastructure
for ACN, I've added the tracing functions to the existing code.
This should make the final commit easier to review, but we can also
now run a "before and after" trace.
No functional changes were made with this commit.
