Reorganize usb source files. Create a new hw/usb/ directory and move
all usb source code to that place. Also make filenames a bit more
descriptive. Host adapters are prefixed with "hch-" now, usb device
emulations are prefixed with "dev-". Fixup paths Makefile and include
paths to make it compile. No code changes.

When creating an USB device the old way, there is no way to specify the
target bus. Thus the warning issued by usb_create makes no sense and
rather confuses our users.
Resolve this by passing a bus reference to the usbdevice_init handler
and letting those handlers forward it to usb_create.

Replace device_init() with generalized type_init().
While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

With the separation of the device lookup (via usb_find_device) and
packet processing we can lookup device and endpoint before setting up
the usb packet. So we can initialize USBPacket->ep early and keep it
valid for the whole lifecycle of the USBPacket. Also the devaddr and
devep fields are not needed any more.

All drivers except usb-hub use usb_generic_handle_packet. The only
reason the usb hub has its own function is that it used to be called
with packets which are intended for downstream devices. With the new,
separate device lookup step this doesn't happen any more, so the need
for a different handle_packet callback is gone.
So we can kill the handle_packet callback and just call
usb_generic_handle_packet directly. The special hub handling in
usb_handle_packet() can go away for the same reason.

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

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.

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.

conditional on a define from config-host.h which is included only later.
Include that file earlier to get the warnings back.

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
