[RFC] Target-defined breakpoints [5/9] notification flags

[Hui Zhu]

Target-defined breakpoint sync function need know when does the notification get because it sync packet that through notification just can be handled when GDB in the right status(I will introduce it clear in sync patch).
This patch add a flags in function handle_notification to help notification handler know about the GDB status.

Thanks,
Hui
