Updates of the RAOP (AirPlay protocol) collection of codes maintained at https://github.com/FD-/RPiPlay.git so it is current as of 2021-08-01, adding all changes since the original release of UxPlay by antimof. This involved crypto updates, replacement of the included plist library by the system-installed version, and a change over to a library llhttp for http parsing.
Added the -s, -o -p, -m, -r, -f, -fps -vs -va and -t options.

If “cmake -DZOOMFIX=ON .” is run before compiling, the mirrored window is now visible to screen-sharing applications such as Zoom. To compile with ZOOMFIX=ON, the X11 development libraries must be installed. (ZOOMFIX will not be needed once the upcoming gstreamer-1.20 is available, since starting with that release, the GStreamer X11 mirror window will be natively visible for screen-sharing.) Thanks to David Ventura https://github.com/DavidVentura/UxPlay for the fix and also for getting it into gstreamer-1.20. [If uxplay was compiled after cmake was run without -DZOOMFIX=ON, and your gstreamer version is older than 1.20, you can still manually make the X11 window visible to screen-sharing apps with the X11 utility xdotool, if it is installed, with: xdotool selectwindow set_window --name <name> (where <name> is your choice of name), and then select the uxplay window by clicking on it with the mouse.]
The AirPlay server now terminates correctly when the gstreamer display window is closed, and is relaunched with the same settings to wait for a new connection. The program uxplay terminates when Ctrl-C is typed in the terminal window. The -t timeout option relaunches the server after timeout seconds of inactivity to allow new connections to be made.
In principle, multiple instances of uxplay can be run simultaneously using the -m (generate random MAC address) option to give each a different (“local” as opposed to “universal”) MAC address. If the -p [n] option is used, they also need separate network port choices. (However, there may be a large latency, and running two instances of uxplay simultaneously on the same computer may not be very useful; using the -fps option to force streaming framerates below 30fps could be helpful.)
