Pi2 and 3 image improvements (GLES, GPIO)

[Alejandro J. Cura]

Perhaps something else is broken, because I'm trying installing
mir-libs, mir-kiosk and mir-kiosk-apps on the latest raspi 2 image (on
a Raspberry Pi 2, of course), and on the amd64 image on a kvm, and I
can't even get mir-kiosk to launch and show the black screen with the
pointer. Both the raspi2 and kvm get stuck at the text mode login.

The following in syslog seems relevant:

Jan 23 07:37:29 localhost snap[1658]: Unknown command line options: --vt 1
Jan 23 07:37:30 localhost snap[1658]:
/snap/mir-kiosk/20/bin/run-miral: line 59:  1674 Terminated
  $SNAP/usr/bin/inotifywait -e modify ${CONFIG_FILE}
Jan 23 07:37:30 localhost snap[1658]: Shutting down miral-kiosk (pid: 1673)
Jan 23 07:37:30 localhost snap[1658]:

process
Jan 23 07:37:30 localhost snap[1658]: miral-kiosk was already dead!

End of last week the demos would crash, and Mir would shut down after a few seconds. After refreshing the core today, I'm getting the very first frame, and when I try to move the mouse I see the cursor make a small jump (perhaps another frame?) and then it all hangs up.
