This commit adds full support for USB 3.0 devices in host and device
mode in the USB core. The patch mostly consists of updating the USB
HUB code to support USB 3.0 HUBs. This patch also add some more USB
controller methods to support more active-alike USB controllers like
the XHCI which needs to be informed about various device state events.

USB 3.0 HUBs are not tested yet, due to lack of hardware, but are
believed to work.

After this update the initial device descriptor is only read twice
when we know that the bMaxPacketSize is too small for a single packet
transfer of this descriptor.

fix a few cases where a string is passed via format argument instead of

Most of the cases looked harmless, but this is done for the sake of
correctness. In one case it even allowed to drop an intermediate buffer.

MFC r208008

If a USB device is suspended and a USB set config request is issued when the
USB enumeration lock is locked, then the USB stack fails to resume the device
because locking the USB enumeration lock is part of the resume procedure. To
solve this issue a new lock is introduced which only protects the suspend and
resume callbacks, which can be dropped inside the usbd_do_request_flags()
function, to allow suspend and resume during so-called enumeration operations.

MFC r207020, r207027, r207072.

Change usb devd events from fake attach to a notify. The ugen device is not a
proper device_t so it faked the devctl event to appear like one, this is now a
notify which allows more information to be passed.

We notify for both the device attach/detach and for each usb interface. A devd
rule can now match on the interface properties, including composite devices
which may have a uvideo interface and also usound and possibly uhid too.

An example to match a umass device with a scsi subclass and BBB protocol would be

notify 100 {
match "system" "USB";
match "subsystem" "INTERFACE";
match "type" "ATTACH";
match "intclass" "0x08";
match "intsubclass" "0x06";
match "intprotocol" "0x50";
action ...
};

The old attach devctl event has been retained for the moment to make merging to
8.1 easier. This was never compatible with 7.x or earlier due to the ugen regex
change needed.

Document the new USB notification types.

Update to current version of head.

Use a more obvious prefix for the USB control (endpoint 0) transfers rather
than default_*.

Properly name the sxlocks, mutexes and condvars.

Use SX_DUPOK rather than making the string unique.

Also add the usb mode to the devd string as the usb controller can work in both
host or device (gadget) modes.
