b9d326c568 man: Ensure notify example includes <string.h>
This ensures that memcpy and strerror are defined.  This is especially
important with GCC 14 as implicit function declarations are now an error.

4cbf560edf man/notify-selfcontained-example: check argument first
This is just good style. In this particular case, if the argument is incorrect and
the function is not tested with $NOTIFY_SOCKET set, the user could not get the
proper error until running for real.

Also, remove mention of systemd. The protocol is fully generic on purpose.

47fba8f925 notify-example: also send STOPPING=1 at exit
I think the example should reflect the full set of lifecycle messages,
including STOPPING=1, which tells the service manager that the service
is already terminating. This is useful for reporting this information
back to the user and to suppress repeated shutdown requests.

It's not as important as the READY=1 and RELOADING=1 messages, since we
actively wait for those from the service message if the right Type= is
set. But it's still very valuable information, easy to do, and completes
the state engine.

383917ac67 man: add self-contained example of notify protocol
We are saying in public that the protocl is stable and can be easily
reimplemented, so provide an example doing so in the documentation,
license as MIT-0 so that it can be copied and pasted at will.
