The transfers require enpoint MPS for proper transaction handling,
assign it in the common place during transfer allsocation so that it can
be reused.
Some users, such as USBIP, may need to keep a reference to private data,
add a parameter for completion callback data.

Address parameter/argument is no longer needed because we have a pointer
to the USB device. The Attrib parameter has never been used and will be
replaced by the interval and start-frame parameters in the future.

Implement the dequeue function and remove the timeout parameter as it is
no longer necessary and can be handled in the upper layer. The dequeue
function is required for the USBIP implementation.

The ctx_shell was only used a single place and in a function
that already has a `sh` that would be better to use.

Add command to get the current device configuration.
Revise the shell part to have a set|get configuration
subcommands.

With the latest change, there is no need for this structure
to be used as a completion handler.

Use the USB device structure and wrappers introduced earlier.
With this patch, users of ch9 requests do not need to work
directly with the UHC API. The requests are now blocked until
there is a response from the UHC. Callers finally have access
to the data buffer and request status.

The current approach is a bit impractical in the upper layer.
This patch removes the two fifos that hold the transfer buffers
and replaces them with a byte array for the setup packet and
a pointer to a data buffer. The data buffer is mandatory for
all types of transfers except control without a data stage.
The waste of eight unused bytes for non-control transfers should
be insignificant, since an additional pointer would be at least
half of it, and then there would be the overhead of handling it.
This patch also clean up the transfer flags, rename owner to callback
as it reflects the upper layer use case, and add an additional member
to hold the pointer to the USB device (peripheral on the bus).

Check that the length of the packet is at least the size of
the descriptor head. Otherwise there may be unpleasant side effects.

This is initial support. Necessary to test the UHC driver API,
for the USB support test implementations, and upcoming USBIP support.
