[PATCH 2/3] gdb/cli: add a 'normal_stop' option to 'cli_suppress_notification'

[Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>]

Extend the 'cli_suppress_notification' struct with a new field,
'normal_stop', that can be used for checking if printing normal stop
events on the CLI should be suppressed.

This patch only introduces the flag.  The subsequent patch adds a user
command to turn the flag off/on.
