If a display is backed by a specialized VC, allow to override the
default "vc:80Cx24C".
As suggested by Paolo, if the display doesn't implement a VC (get_vc()
returns NULL), use a fallback that will use a muxed console on stdio.
This changes the behaviour of "qemu -display none", to create a muxed
serial/monitor by default (on TTY & not daemonized).
This breaks existing command line setups -- if I say
"-display none" I just mean "don't do a display", not
"please also give me a monitor". We already have a
"do what I mean" option for "no graphics", which is
"-nographic". The advantage of -display none is that
it does only and exactly what it says it does.
Setups using semihosting for output now get a spurious
load of output from the monitor on their terminal.
I think we should revert this; I'll send a patch.
Yes indeed. I think this may be why I've seen my xterm go into strange i/o modes during
"make check-tcg" of the semihosting tests.
