Implement "info chardev" command. (Gerd Hoffmann)
This patch makes qemu keep track of the character devices in use and
implements a "info chardev" monitor command to print a list.
qemu_chr_open() sticks the devices into a linked list now. It got a new
argument (label), so there is a name for each device. It also assigns a
filename to each character device. By default it just copyes the
filename passed in. Individual drivers can fill in something else
though. qemu_chr_open_pty() sets the filename to name of the pseudo tty
allocated.
Output looks like this:
(qemu) info chardev
monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait
serial0: filename=unix:/tmp/run.sh-26827/console,server
serial1: filename=pty:/dev/pts/5
parallel0: filename=vc:640x480
