[PATCH 0/9] audio: remove deprecated QEMU_AUDIO env support

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

This removes much of the deprecated audio code, most
notably the QEMU_AUDIO env variables. The VNC server
will also stop accepting client requests for audio
streaming unless an audiodev is set.

I tried to make the use of 'audiodev' mandatory for
devices but that turned out to not be practical. Our
test suite assumes it can create any device type
without setting any properties. This is not possible
if 'audiodev' setting is enforced at realize() time.
Also there are several machihe boards with embedded
soundcards that provide no way to set audiodev AFAICT

Daniel P. Berrangé (9):
  audio: don't check qemu_add_vm_change_state_handler failure
  audio: remove special audio_calloc function
  audio: remove unused 'name' in QEMUSoundCard struct
  audio: remove QEMUSoundCard linked list
  audio: remove empty AUD_remove_card method
  docs: split the deprecation warning for soundcards vs VNC
  ui/vnc: don't accept VNC_ENCODING_AUDIO without audiodev
  audio: audio state is now mandatory for capture
  audio: remove support for QEMU_AUDIO_ env variables
