Norman Feske 441d672440 Improved interactive GDB monitor run script
The new 'gdb_monitor_interactive.run' script extends the original
'gdb_monitor.run' script with a startup sequence that automates the
initial break-in at the main function of a dynamically linked binary.
Patch by Christian Prochaska.
