Added an option to pause and resume the script while running to
allow the user to review the output. Previously, a synthetic probe
was being displayed in the probe list, this is now removed.
* elaborate.cxx:
- monitor_mode_write: skip generating probe point
condition for synthetic probes. Add command to resume
and pause all probes.
- semantic_pass: call monitor_mode_{read, write} in init
* staprun/monitor.c: Bind keys for pause and resume.
