Unable to stop Unbound in Windows console (does not respond to CTRL+C command)

Unable to stop Unbound in Windows console (does not respond to CTRL+C command).
I have not met another application that does not know how to stop on CTRL + C. Fix this glaring bug please.

To reproduce
unbound.exe -d -p -c unbound.conf
then
CTRL+C

System:

• Unbound version: 1.15.0
• OS: Windows
• unbound -V output: Version 1.15.0

Thanks for the report! The issue is likely that there was no SIGBREAK handling in some parts of the code. The commit patches this to add the SIGBREAK handler to the list of signals that causes unbound to stop, much like SIGINT on Linux and FreeBSD.

This adds the code to the repository, and it is an improvement. I do not know if it actually works now for you, but it seems very likely.
