/* Print a call tree containing all annotated functions.
The call structure of the functions is represented using
indentation and vertical lines. Extra information is printed using
horizontal lines that connect to the vertical line.
The return value is represented using the arrow "->>". For simple
functions, the arrow can be printed on the same line as the
function name. If more output is printed, it is connected to the
vertical line of the function.
The first column contains the file name, the second the line
number, and the third a number increasing for each trace line.
Note, when trace output from several threads are mixed, the output
can become misaligned, as all threads (currently) share one state.
This is post prominent when the EVENTS part is enabled.
Note that the trace system, when enabled, uses the GCC/Clang
"cleanup" extension. */
