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.

This patch adds fields to the USBDevice struct for the current
speed (hard-wired to full speed for now) and current device
configuration. Also a init function is added which inializes
these fields. This allows USB_REQ_{GET,SET}_CONFIGURATION
handling to be moved to common code.
For most drivers the conversion is trivial ad they support a single
configuration only anyway. One exception is bluetooth where some
device-specific setup code runs after get/set configuration. The
other is usb-net which actually has two configurations so the
the code to check for the active configuration has been adapted.

Switch the usb serial drivers (serial, braille) over to the
new descriptor infrastructure.
Note that this removes the freely configurable vendor and product id
properties. I think the only reason this was configurable is that the
only difference between the serial and the braille device is the
vendor+product id. Of course the serial and braille devices keep their
different IDs, but they can't be overritten from the command line any
more.

error_report() terminates the message with a newline. Strip it it
from its arguments.
This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for
IFF_VNET_HDR available" (all three versions).
There's one place that passes arguments without newlines
intentionally: load_vmstate(). Fix it up.
If -usbdevice is used on a machine with no USB busses, usb_create
will fail and return NULL. Patch below handles this failure gracefully
rather than crashing when we try to init the device.

This fixes a segfault due to buffer overrun in the usb-serial device.
The memcpy was incrementing the start location by recv_used yet, the
computation of first_size (how much to write at the end of the buffer
before wrapping to the front) was not accounting for it. This causes the
next element after the receive buffer (recv_ptr) to get overwritten with
random data.

Since commit 747bbdf7 QEMU_WARN_UNUSED_RESULT is never defined as it is
conditional on a define from config-host.h which is included only later.
Include that file earlier to get the warnings back.
Reactivating it unfortunately leads to some warnings about unused qdev_init
results. These calls are changed to qdev_init_nofail to avoid build failures.

Implement the serial break via usb serial.
The second data byte in ftdi status packet contains the break status.
The values were already defined in usb-serial.c so it was a matter of
making use of the event_trigger to form a urb to send over to the host
controller with the serial break status set.
This was tested against a linux development image which enables sysrq
via a serial break on the ftdi usb console.

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

The variables recv_ptr and recv_used are not large enough to hold
