New functionality: Script tracing!
With script tracing, you can better understand the flow of execution in the OpenSIPS script.
Moreover, you can also trace the values of pseudo-variables, as script execution progresses.

The blocks of the script where script tracing is enabled will print a line for each individual
action that is done (e.g. assignments, conditional tests, module functions, core functions, etc.).
Multiple pseudo-variables can be monitored by specifying a pv_format string
(e.g. "$ru---$avp(var1)"). The current value of the format will be printed along with each line.

The logs of multiple traced regions of your script can be differentiated by specifying an
additional plain string as the 3rd parameter.

Script tracing can be enabled with: script_trace(log_level, pv_format_string[, info_string])
To disable script tracing, just: script_trace()
