Don't report errors on devices which are in disconnected
and closing state.

Two fixes for the price of one ;)
First, reinitialize the endpoint table after device reset.
This is needed anyway as the reset might have switched interfaces.
It also clears the endpoint halted state.
Second the CLEAR_HALT ioctl wants a unsigned int passed in as
argument, not uint8_t.
This gets my usb sd card reader (sandisk micromate) going.

It is perfectly fine to leave the usb device in unconfigured state
(USBHostDevice->configuration == 0). Just do that and wait for the
guest to explicitly set a configuration. This is closer to what real
hardware does and it also simplifies the device initialization. There
is no need to figure how the device is configured on the host.

USB Devices can have up to 15 IN and 15 OUT endpoints, not 15 endpoints
total. Move from one array to two arrays (one IN, one OUT) to maintain
the endpoint state.

This patch adds code to do minimal siTD handling, which is basically
just following the next pointer. This is good enougth to handle the
inactive siTDs used by FreeBSD. Active siTDs are skipped too as we
don't have split transfer support in qemu, additionally a warning is
printed.

actually does), so we must not touch it after the callback returns.

This patch makes qemu assign a port when creating the device, not when
attaching it. For most usb devices this isn't a noticable difference
because they are in attached state all the time.
The change affects usb-host devices which live in detached state while
the real device is unplugged from the host. They have a fixed port
assigned all the time now instead of getting grabbing one on attach and
releasing it at detach, i.e. they stop floating around at the usb bus.
The change also allows to simplify usb-hub. It doesn't need the
handle_attach() callback any more to configure the downstream ports.
This can be done at device initialitation time now. The changed
initialization order (first grab upstream port, then register downstream
ports) also fixes some icky corner cases. For example it is not possible
any more to plug the hub into one of its own downstream ports.
The usb host adapters must care too. USBPort->dev being non-NULL
doesn't imply any more the device is in attached state. The host
adapters must additionally check the USBPort->dev->attached flag.
