Allows to remove one FIXME. Makes LIBUSB_LOG_LEVEL_WARNING build errors
go away. And starting with that version libusb has a LIBUSBX_API_VERSION
define which allows to easily #ifdef version dependencies should that
need arrive in the future.

Report the supported speeds for device and port in the error message.
Also add the speeds to the tracepoint. And while being at it drop
the redundant error message in usb_desc_attach, usb_device_attach will
report the error anyway.

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.

usb-serial has a qdev chardev property, and hw/qdev-properties-system.c
already contains:
static void release_chr(Object *obj, const char *name, void *opaque)
{
DeviceState *dev = DEVICE(obj);
Property *prop = opaque;
CharDriverState **ptr = qdev_get_prop_ptr(dev, prop);
CharDriverState *chr = *ptr;
if (chr) {
qemu_chr_add_handlers(chr, NULL, NULL, NULL, NULL);
qemu_chr_fe_release(chr);
}
}
So doing the qemu_chr_add_handlers(s->cs, NULL, NULL, NULL, NULL); from
the usb handle_destroy function too will lead to it being done twice.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

usb-storage takes care to fetch the USB serial number from -drive
options, but it neglected to pass its own 'serial' property to the
scsi-disk it creates. With this patch, the 'serial' qdev property and
the 'serial' option in -drive behave the same and correctly apply the
serial number on both USB and SCSI level.

Most frontends can't really determine if the guest actually has the frontend
side open. So lets automatically generate fe_open / fe_close as soon as a
frontend becomes ready (as signalled by calling qemu_chr_add_handlers) /
becomes non ready (as signalled by setting all handlers to NULL).
And allow frontends which can actually determine if the guest is listening to
opt-out of this.

qdev-monitor.c is the only "core qdev" file that is not used in
user-mode emulation, and it does not define anything that is used
by hardware models. Remove it from the hw/ directory and
remove hw/qdev-monitor.h from hw/qdev.h too; this requires
some files to have some new explicitly includes.
