aliguori 5ccfae10a7 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

aurel32 8109b9b6bf [PATCH] usb-serial: Fix data corruption with usb serial emulation
* Remove the unused send_buf variable and its constant.

* Fix a math error
  The variables recv_ptr and recv_used are not large enough to hold
  the constant 384, which causes data corruption when the pointer is
  reset with: s->recv_ptr = (s->recv_ptr + len) % RECV_BUF;
