0046e0b1c2 qemuxml2argvtest: Use internal wrapping of command line arguments
virCommandToString has the possibility to return an already wrapped
string with better format than what we get from the test wrapper script.

The main advantage is that arguments for an option are always on the
same line which makes it more easy to see what changed in a diff and
prevents re-wrapping of the line if a wrapping point moves over the
threshold.

Additionally the used output is the same we have in the VM log file when
a VM is starting.

f763b6e439 qemu: capabilities: Enable detection of QEMU_CAPS_OBJECT_QAPIFIED
Base the detection on the presence of the 'secret' qom-type entry, which
isn't conditionally compiled in qemu.

All caps-based test now switch to using JSON for -object.

d96fb5cb31 qemu: add support for generating -audiodev arguments
The -audiodev argument is replacing the QEMU_AUDIO_DRV env variable (and
its relations).

Sadly we still have to use the SDL_AUDIODRIVER env variable because that
wasn't mapped into QAPI schema.

43c9c0859f qemu: use long on|off syntax for -chardev boolean option values
The preferred syntax for boolean options is to set the value "on" or
"off". QEMU 7.1.0 will deprecate the short format we currently use.

The long format has been supported with -chardev since at least 1.5.3,
so we don't need to check for it.
