usb-redir: Don't delay handling of open events to a bottom half

There is no need for this, and doing so means that a backend trying to
write immediately after an open event will see qemu_chr_be_can_write
returning 0, which not all backends handle well as there is no wakeup...

usb-redir: Get rid of async-struct get member

This is a preparation patch for completely getting rid of the async-packet
struct in usb-redir, instead relying on the (new) per ep queues in the
qemu usb core.

usb-redir: Get rid of local shadow copy of packet headers

The shadow copy only serves as an extra check (besides the packet-id) to
ensure the packet we get back is a reply to the packet we think it is.

This check has never triggered in all the time usb-redir is in use now,...

usb-redir: Get rid of unused async-struct dev member

This is a preparation patch for completely getting rid of the async-packet

qemu usb core.

usb-redir: Return babble when getting more bulk data then requested

Babble is the appropriate error in this case (rather then signalling a stall).

usb-redir: Convert to new libusbredirparser 0.5 API

This gives us support for 64 bit ids which is needed for using XHCI with
the new hcd generated ids.

ehci: Handle USB_RET_PROCERR in ehci_fill_queue

USB_RET_PROCERR can be triggered by the guest (by for example requesting more
then BUFFSIZE bytes), so don't assert on it.

ehci: Correct a comment in fetchqtd packet processing

Since my previous comment said "Should never happen", I tried changing the
next line to an assert(0), which did not go well, which as the new comments
explains is logical if you think about it for a moment....

usb-redir: Never return USB_RET_NAK for async handled packets

USB_RET_NAK is not a valid response for async handled packets (and will
trigger an assert as such).

Also drop the warning when receiving a status of cancelled for packets not
cancelled by qemu itself, this can happen when a device gets unredirected...
