Raspberry Pi 4 hw support

[Debayan Sutradhar]

I have a large embedded project for raspberry pis (https://stream-pi.com)
and recently its discord server crosses 60 members and growing every month.
Unfortunately it seems that Hardware acceleration doesnt work on VideoCore
VI.

If es2 pipeline is used, the program exits after the output "* failed to
add service - already in use?"

Hence for now we are using sw pipeline to use javafx apps. That makes them
very slow and touch gestures don't work as expect.
