For usbser.sys driver, which is the default USB host driver for CDC
devices in windows, it is expected that USB device always indicate
completion of transmission by short packet. In case where the last
packet length is multiple of max packet size of the BULK IN endpoint,
the USB device shall indicate completion of transmission by sending a
zero length packet. This commit adds the sending of the short packet
termination mentioned above, ensuring condition of short packet
terminate is fulfilled.

Pass the report buffer originally provided in hid_device_submit_report()
as a parameter to input_report_done() callback. Example use case is to
enable HID report multi buffering which is easiest achieved by
allocating report buffer before submitting it and then releasing the
buffer after it has been sent.

The consequences of a wSequence mismatch are unspecified and are
primarily for debugging purposes. Our checks are a bit too strict, and
if the header check fails, the sequence is not updated, and the header
check subsequently fails. Rework the code to just log a warning on
mismatch and also reset OUT sequence counter the same way as the IN
sequence counter.

We need to handle notifications periodically, for example, when the
interface alternate changes and we also need to track whether the
notification was actually transfered to the host. There is no need to
trigger notification work on iface_start/iface_stop when the USB
interface is not in active configuration. This commit intentianly
changes log level in the notification handling code.

The implementation should not assume that NDP is placed immediately

Application is expected to call usbd_uac2_send() on each enabled USB
Streaming Output Terminal (isochronous IN data endpoint) exactly once
every SOF. The class is bookkeeping queued transfers to make it easier
to determine component at fault when things go wrong. However, this
approach only works fine if the underlying USB device controller buffers
the data to be sent on next SOF and reports the transfer completion
immediately after data is buffered (e.g. nRF52 USBD).
While DWC2 otg also requires the SW to arm endpoint with data for the
next SOF, unlike nRF52 USBD the transfer is only considered complete
after either the IN token for isochronous endpoint is received or after
the Periodic Frame Interval elapses without IN token. This design
inevitably requires the application to be able to have at least two
buffers for isochronous IN endpoints.
Support dual buffering on IN data endpoints to facilitate sending
isochronous IN data on every SOF regardless of the underlying USB device
controller design.

In case the host doesn't pull the new data from the endpoint, the work task
would schedule itself again delayed (at the max. priority). When there is
no terminal program or active application reading the endpoint this
results in a constant polling of the endpoint burning up to 5% of the
CPU cycles.
By using a atomic flag for tx busy, the polling is solved and changed into
a postponed execution of the next work task which saves up to 5% of
CPU cycles and allows a better real-time behavior for other tasks.
Secondly, if the TX interrupt is disabled but there is still data in the TX
FIFO (ring buffer), the implementation will continue to trigger subsequent
TX work and attempt to flush the data to the host.

Verbatim from USB 2.0 specification:
The Remote Wakeup field indicates whether the device is currently enabled
to request remote wakeup. The default mode for devices that support
remote wakeup is disabled. If D1 is reset to zero, the ability of the
device to signal remote wakeup is disabled. If D1 is set to one,
the ability of the device to signal remote wakeup is enabled.
The Remote Wakeup field can be modified by the SetFeature() and
ClearFeature() requests using the DEVICE_REMOTE_WAKEUP feature selector.
This field is reset to zero when the device is reset.
