Allow -serial chardev:<name>
Lets put -chardev into use now. With this patch applied chardev:name is
accepted as chardev specification everywhere, i.e. now you can:
-chardev stdio,id=ttyS0
-serial chardev:ttyS0
which does the same as '-serial stdio".
Muxing can be done this way:
-chardev stdio,id=mux,mux=on
-serial chardev:mux
-monitor chardev:mux
You can mux more than two streams.
