be62a2ebab Strip trailing '\n' from error_report()'s first argument (again)
Commit 6daf194d got rid of them, but Hans and Gerd added some more
lately.  Tracked down with this Coccinelle semantic patch:

@r@
    expression fmt;
    position p;
@@
    error_report(fmt, ...)@p
@script:python@
    fmt << r.fmt;
    p << r.p;
@@
if "\\n" in str(fmt):
    print "%s:%s:%s:%s" % (p[0].file, p[0].line, p[0].column, fmt)

c1b71a1df6 usb-redir: Don't try to write to the chardev after a close event
Since we handle close async in a bh, do_write and thus write can get
called after receiving a close event. This patch adds a check to
the usb-redir write callback to not call qemu_chr_fe_write on a closed
backend.

99f08100cd usb-redir: Device disconnect + re-connect robustness fixes
These fixes mainly target the other side sending some (error status)
packets after a disconnect packet. In some cases these would get queued
up and then reported to the controller when a new device gets connected.

* Fully reset device state on disconnect
* Don't allow a connect message when already connected
* Ignore iso and interrupt status messages when disconnected

65f9d98673 usb-redir: Call qemu_chr_fe_open/close
To let the chardev now we're ready start receiving data. This is necessary
with the spicevmc chardev to get it registered with the spice-server.

4f4321c11f usb: use iovecs in USBPacket
Zap data pointer from USBPacket, add a QEMUIOVector instead.
Add a bunch of helper functions to manage USBPacket data.
Switch over users to the new interface.

Note that USBPacket->len was used for two purposes:  First to
pass in the buffer size and second to return the number of
transfered bytes or the status code on async transfers.  There
is a new result variable for the latter.  A new status code
was added to catch uninitialized result.

Nobody creates iovecs with more than one element (yet).
Some users are (temporarely) limited to iovecs with a single
element to keep the patch size as small as possible.

69354a8334 USB: add usb network redirection support
This patch adds support for a usb-redir device, which takes a chardev
as a communication channel to an actual usbdevice using the usbredir protocol.

Compiling the usb-redir device requires usbredir-0.3 to be installed for
the usbredir protocol parser, usbredir-0.3 also contains a server for
redirecting usb traffic from an actual usb device. You can get the 0.3
release of usbredir here:
http://people.fedoraproject.org/~jwrdegoede/usbredir-0.3.tar.bz2
(getting a more formal site for it is a WIP)

Example usage:
1) Start usbredirserver for a usb device:
sudo usbredirserver 045e:0772
2) Start qemu with usb2 support + a chardev talking to usbredirserver +
   a usb-redir device using this chardev:
qemu ... \
  -readconfig docs/ich9-ehci-uhci.cfg \
  -chardev socket,id=usbredirchardev,host=localhost,port=4000 \
  -device usb-redir,chardev=usbredirchardev,id=usbredirdev
