Add separate detach callback to USBPortOps, split
uhci/ohci/musb/usbhub attach functions into two.
Move common code to the usb_attach() function, only
the hardware-specific bits remain in the attach/detach
callbacks.
Keep track of the port it is attached to for each usb device.

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.

This patch adds hw/usb-desc.[ch] files. They carry data structures
for various usb descriptors and helper functions to generate usb
packets from the structures.
The intention is to have a internal representation of the device
desription which is more usable than the current char array blobs,
so we can have common code handle common usb device emulation using
the device description.
The usage of this infrastructure is optional for usb drivers as there
are cases such as pass-through where it probably isn't very useful.

Commit d85d0d3883f5a567fa2969a0396e42e0a662b3fa introduces a regression
with Windows ME that leads to a division by 0 and a crash.
It uses the color expansion rop with the source pitch set to 0. This is
something allowed, as the manual explicitely says "When the source of
color-expand data is display memory, the source pitch is ignored.".
This patch fixes this regression by computing sx, sy and others
variables only if they are going to be used later, that is for a plain
copy ROP. It basically consists in moving code.

On big endian hosts, the curses interface is unusable: the emulated
graphic card only displays garbage, while the monitor interface displays
nothing (or rather only spaces).
The curses interface is waiting for data in native endianness, so
console_write_ch() should not do any conversion. The conversion should
be done when reading the video buffer in hw/vga.c. I supposed this
buffer is in little endian mode, though it's not impossible that the
data is actually in guest endianness. I currently have no big endian
guest to way (they all switch to graphic mode immediately).

The device path used for migration is currently broken for
for all devices behind a nested bridge.
Replace this by a hierarchical list of slot/function numbers, walking
the path from root down to device. Add :00 after the domain number
so that if there are no nested bridges, this is compatible
with what we have now.
Note: as pointed out by Gleb, using openfirmware paths
might be cleaner, doing this would break compatibility though,
and the IDs used are not guest or user visible at all,
so breaking the compatibility is probably not worth it.

The issue is, it is assumed that all qbuses, qdeves are under
main_system_bus. But there are qbuses whose parent is NULL. So it
is necessary to trigger reset for those qbuses.
(On the other hand, if NULL is passed to qdev_create(), its parent bus
is main_system_bus.)
Ideally those buses should be moved under bus controller
device which is qdev. But it's not done yet.
So register qbus reset handler for qbus whose parent is NULL.

Using bus numbers in migration is clearly wrong as
they are guest assigned. Not really sure what the
right thing to do is, for now stick 0 in there so things
keep working for non-nested setups, add a TODO.
We also probably have to mark nested bridges as non-migrateable
until this is fixed?

ledma has 0x20 bytes of registers according to OBP, and at least Solaris9
reads the 5th register which is beyond what we've mapped. So let's setup
a flag (inspired by a previous patch from Blue Swirl) to identify ledma
from espdma, and map another 16 bytes of registers which return 0.

This function can be called multiple times throughout the lifetime of a
