USB generic driver
When a USB error occurs that might indicate that the device has been
unplugged, don't resubmit the URB immediately to prevent flooding the
log with error messages before khubd has us disconnect()ed.

The HP nx6110 laptop needs to have Headphone Jack Sense enabled so
that the internal speakers will be turned off when headphones are
plugged in.
Also ac97_quirk=hp_only is needed to make a single Master volume in
the mixer instead of separate volumes for internal speakers and
headphones, which just confuses the user.

With the double buffering, we no longer need contiguous memory for the
PCM buffer, so we can use vmalloc() instead of the preallocation
functions, and increase the maximum size to 256 KB.

We always had to use double buffering when capturing, and when playback
data for one URB crosses a buffer boundary. The latter would make hwptr
updates less precise because the double-buffered data is read from the
buffer much earlier than the other data is read by the host controller.
Double-buffering all data allows to update hwptr immediately after the
data was copied to the USB buffer(s), which has the additional benefit
of avoiding the latency imposed by the host controller's delay of up to
one frame when interrupting.

When preparing capture URBs, we don't need to stop when we cross a
period boundary because we now never handle more than one millisecond of
data per URB anyway.
When handling captured data, use an extra flag to call
snd_pcm_period_elapsed() no more than once. This allows us to move the
period boundary checking code before the copying of the data which
avoids a second locking of the substream's lock.

The EHCI driver doesn't interrupt more than once per millisecond, and
organizes all iso transfers with frame-sized ITDs, so we can (try to)
be more efficient by aligning all URBs on frame boundaries.

When determining how many packets are needed for one period, we cannot
assume that all packets have their maximum size -- we always use the
nominal sample rate when sending data, and could use an even lower rate
when the endpoint uses frequency feedback.
