ed6d949afd - Make struct usb_xfer opaque so that drivers can not access the internals 
- Reduce the number of headers needed for a usb driver, the common case is just   usb.h and usbdi.h

ae60fdfba2 Rename usb pipes to endpoints as it better represents what they are, and struct 
usb_pipe may be used for a different purpose later on.

b9c81a5dce Make sure the frame list base address is re-programmed after stopping the USB 
schedule, in case the hardware clears the frame list base address.

ec8f31275d Revert part of r191494 which used the udev state to mark suspending, this needs 
to be set via two variables (peer_suspended and self_suspended) and can not be
merged into one.

bd21677868 Track the usb device state as its powered on, addressed and configured. This helps 
to avoid touching the device when it is not going to respond and would otherwise
timeout.

Implement the suspend tracking as a udev state too.

Change the roothub exec functions to take the usb request and data pointers
directly rather than placing them on the parent bus struct.

fde875265f Provide a better commit log for r190735, forced by making a whitespace change. 
Refactor how we interface with the root HUB. This is achieved by making a
direct call from usb2_do_request to the host controller for root hub requests,
this call will perform the controller specific register read/writes and return
the error code.

This cuts out a lot of code in the host controller files and saves one thread
per USB bus.

Some cancelable flags are always true.  Substitute these away. These cancelable
flags were mostly useful with the root HUB which is now handled differently.

Refactor how we interface with the root HUB. This cuts around 1200 lines of
code totally and saves one thread per USB bus.

Workaround for buggy USB hardware not handling new SETUP packet before STATUS
stage is complete, this allows xfers to endpoint0 to return a short frame.

- Move tunable defines into usb_core.h and dependancy towards usb_defs.h
- Leave hardcoded defines in "usb_defs.h".
- Allow overriding all tunable defines.
- Add more customisable typedefs.
- Correct maximum device number.

Clean up old way of polling the USB hardware.  The existing polling support was
a bit hackish.
