Wireless USB endpoint state has a sequence number and a current
window and not just a single toggle bit. So allow HCDs to provide a
endpoint_reset method and call this or clear the software toggles as
required (after a clear halt, set configuration etc.).
usb_settoggle() and friends are then HCD internal and are moved into
core/hcd.h and all device drivers call usb_reset_endpoint() instead.
If the device endpoint state has been reset (with a clear halt) but
the host endpoint state has not then subsequent data transfers will
not complete. The device will only work again after it is reset or
disconnected.

The client_register and client_unregister methods are optional so
there is no point in defining stub ones. Especially when these methods
are likely to be removed soon.

Previously all resolution setting was done with precalculated tables.
When the image is vflipped we need to adjust the alignment which would
require another table. Now we can adjust the parameters on the fly instead.

Remove support for the debug call VIDIOC_INT_S_AUDIO_ROUTING from cx18
and ivtv. These internal ioctls shouldn't be exposed. These were only
used through the cx18-ctl and ivtv-ctl utilities, and only when testing
a new card variant.
This cleanup allows the removal of this ioctl from v4l2-common.h.
