While the qemu-storage-daemon command line is still considered unstable,
let's change --chardev from the old QemuOpts-based parser to QAPI, so
that it becomes a simple mapping of chardev-add to the command line and
will fit in a future fully QAPIfied command line without later
incompatible changes or additional compatibility glue.

v2:
- Use g_autoptr in qemu_chr_print_types() [Marc-André]
- Fixed build failures with spice [Marc-André]
- Fixed documentation generation [Markus]
- Make sure that no simple union variant contains a 'data' branch that
  would make conversion to flat representation much more complicated

Kevin Wolf (6):
  char/stdio: Fix QMP default for 'signal'
  char: Factor out qemu_chr_print_types()
  qapi: Remove wrapper struct for simple unions
  qapi: Optionally parse simple unions as flat
  tests/qapi-schema: Flat representation of simple unions
  qemu-storage-daemon: Use qmp_chardev_add() for --chardev
