John Marino 6f0ddd3c6b devel/ahven: Improve symbolic traceback functionality
Rather than show the lengthy and not helpful trace of the Ahven
Framework when a symbolic trace is shown, detect the start of this
infrastructure trace and truncate it there.  This helps debugging
greatly by removing a lot of noise.
