[PATCH 0/2 for 6.2] Fix compiler warnings on Fedora 35 / CLang

["Daniel P. Berrangé" <berrange@redhat.com>]

Current QEMU git master caused compiler warnings on Fedora 35 when using
CLang. It is expected to affect any distro with CLang >= 13.0.0

Since QEMU builds with -Werror by default we should fix these warnings
before release, as this version of QEMU will increasing trigger the
warnings as more distros pull in CLang >= 13.0.0

The spice patch was from John's series at

  https://lists.gnu.org/archive/html/qemu-devel/2021-11/msg01056.html

I pulled out this patch on its own as the above series isn't likely
suitable for merging as a whole during freeze.

The clipboard patch is an alternative impl to what John posted.

Daniel P. Berrangé (1):
  ui: avoid compiler warnings from unused clipboard info variable

John Snow (1):
  spice: Update QXLInterface for spice >= 0.15.0
