[6830] Implement custom exit codes on server shutdown/restart

Browse source 
Added the possibility to use custom process return values
instead of hardcoded 0 (shutdown) or 2 (restart) to allow using them
for various custom external features / better handling.

This can be used through 4 commands in ".server" family:
 - shutdown
 - restart
 - idleshutdown
 - idlerestart

Those have from now on 2 arguments, where the second (return value)
is optional:

.server <command> <time> [return_value]

If return_value is not specified, default value (0 or 2) is used.

Set restart exist code for SIGINT singnal case.
Some code simplifications for original patch.
Related code cleanups.
