fix race condition during stream exit and a fast subsequent setup/play request

[adskicker]

I experienced issues during channel switching from VLC player. When termination of dvb process is longer than the RTSP next setup/play request, a race condition occurred which made the setup/play request to be ignored.

This commit fix this by managing an exiting status that is checked in the setup/play request evaluation.

Hi,
do you have a way to reproduce the race easily?

Hello Samuel,

Thanks for getting back to me on this, and thanks also for the quality of this project, great job !

The setup I use is the following:

• PI4 B 2go with bullseye os version
• Raspberry TV HAT + Dvbjet
• VLC playing the m3u8 provided by watchtv locally (directly from the PI4) or remotely (from Wifi local network on ubuntu 22.04 laptop)

The issue happened quite often during zapping (next / previous channel) in VLC. The effect of the issue is to have a really long zapping time and channels skipped during zapping.

Let me know if you would like more information to reproduce it on your end. I should be able to produce some log output / network capture showing the issue if needed.

Thanks.
