Few patches to be able to build QEMU on macOS 12 (Monterey).

This basically consists of adapting deprecated APIs. I am not
sure about these APIs, so tagging as RFC.

I couldn't succeed to adapt the Cocoa code.

CI job added to avoid bitrotting (ignoring the Objective C
deprecation warning).

Philippe Mathieu-Daudé (6):
  configure: Allow passing extra Objective C compiler flags
  audio/coreaudio: Remove a deprecation warning on macOS 12
  block/file-posix: Remove a deprecation warning on macOS 12
  hvf: Make hvf_get_segments() / hvf_put_segments() local
  hvf: Remove deprecated hv_vcpu_flush() calls
  gitlab-ci: Support macOS 12 via cirrus-run
