switch chardev to QemuOpts: infrastructure, null device
start switching chardevs to QemuOpts. This patch adds the
infrastructure and converts the null device.
The patch brings two new functions:
qemu_chr_open_opts()
same as qemu_chr_open(), but uses QemuOpts instead of a
option char string.
qemu_chr_parse_compat()
accepts a traditional chardev option string, returns the
corresponding QemuOpts instance, to handle backward
compatibility.
The patch also adds a new -chardev switch which can be used to create
named+unconnected chardevs, like this:
-chardev null,id=test
This uses the new qemu_chr_open_opts. Thus with this patch alone only
the null device works. The other devices will follow ...
