This patch adds a serial property for all usb devices, which can be
used to set the serial number of a usb device (as listed by lsusb -v)
to a specific value. Applies to emulated devices only.

The SysBus qdev initfn merely calls SysBusDeviceClass::init, so we can
replace it with a realizefn already. This avoids getting into any initfn
ambiguity with the upcoming Faraday EHCI implementation.
Rename internal usb_ehci_initfn() to usb_ehci_realize() to allow to
return Errors from common initialization code as well.

Due to various unfortunate reasons we cannot reliable detect a guest
cancelling a packet as soon as it happens, instead we detect cancels
with some delay.
When packets are handled async, and we directly pass the guest memory for
the packet to the usb-device as iovec, this means that the usb-device can
write to guest-memory which the guest has already re-used for other purposes
-> not good!
This patch fixes this by adding an intermediate buffer and writing back not
only the result, but also the data, of async completed packets when scanning
the schedule.

Alloes to pass through usb2 devices on usb1 host controllers if possible.
Brings the libusb implementation to feature-parity with the linux usbfs
code, so the usb-host implementation in 1.5 (libusb) doesn't regress
compared to 1.4 (usbfs).

We don't support T=1 so we shouldn't advertise it by default.
Two independent changes:
* Default ATR
sets T=0. This gets overwritten by the client provided ATR later.
* Class descriptor
changes dwAdvertise dwProtocols.PPPP to 0x1 and dwProtocols.RRRR=0 per spec.

Introduces a new utility function: parse_debug_env to avoid code
duplication.
This overrides whatever debug value is set on the corresponding devices
from the command line, and is meant to ease the usage with any
management stack. For libvirt you can set environment variables by
extending the dom namespace, i.e:
<domain type='kvm' id='3' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
<qemu:commandline>
<qemu:env name='QEMU_CCID_PASSTHRU_DEBUG' value='4'/>
<qemu:env name='QEMU_CCID_DEBUG' value='4'/>
</qemu:commandline>
</domain>

With pipelining it is possible to encounter a finished packet when cleaning
the queue due to a halt. This happens when a non stall error happens while
talking to a real device. In this case the queue on the usb-host side will
continue processing packets, and we can have completed packets waiting in
the queue after an error condition packet causing a halt.
There are 2 reasons to discard the completed packets at this point, rather
then trying to writing them back to the guest:
1) The guest expect to be able to cancel and/or change packets after the
packet with the error without doing an unlink, so writing them back may
confuse the guest.
2) Since the queue does not advance when halted, the writing back of these
packets will fail anyways since p->qtdaddr != q->qtdaddr, so the
ehci_verify_qtd call in ehci_writeback_async_complete_packet will fail.
Note that 2) means that then only functional change this patch introduces
is the printing of a warning when this scenario happens.
Note that discarding these packets means that the guest driver and the device
will get out of sync! This is unfortunate, but should not be a problem since
with a non stall error (iow an io-error) the 2 are out of sync already anyways.
Still this patch adds a warning to signal this happening.
Note that sofar this has only been seen with a DVB-T receiver, which gives
of a MPEG-2 stream, which allows for recovering from lost packets, see:

Reimplement usb-host on top of libusb.
Reasons to do this:
(1) Largely rewritten from scratch, nice opportunity to kill historical
cruft.
(2) Offload usbfs handling to libusb.
(3) Have a single portable code base instead of bsd + linux variants.
(4) Bring usb-host support to any platform supported by libusbx.
For now this goes side-by-side to the existing code. That is only to
simplify regression testing though, at the end of the day I want remove
the old code and support libusb exclusively. Merge early in 1.5 cycle,
remove the old code after 1.5 release or something like this.
Thanks to qdev the old and new code can coexist nicely on linux. Just
use "-device usb-host-linux" to use the old linux driver instead of the
libusb one (which takes over the "usb-host" name).
The bsd driver isn't qdev'ified so it isn't that easy for bsd.
I didn't bother making it runtime switchable, so you have to rebuild
qemu with --disable-libusb to get back the old code.
