The whole point of making some of the drivers automatically selected
unless 'EMBEDDED' was to handle quirks transparently after their separation
from the generic core.

Over time, some of the later-added quirks grew into more standalone drivers,
implementing non-trivial features a being larger than a few bytes of code.

In addition to that, some of the standalone drivers don't make sense for
99.9% of the users, as they are very specific to rare devices.

Therefore build by default in only those drivers which

- we historically used to support even before quirk separation from the
  core code
- are isolated enough and likely to hit quite large portion of the
  users anyway (Microsoft, Logitech)

For more clearance what the functions actually do,

  usb_buffer_alloc() is renamed to usb_alloc_coherent()
  usb_buffer_free()  is renamed to usb_free_coherent()

They should only be used in code which really needs DMA coherency.

All call sites have been changed accordingly, except for staging
drivers.

This patch (as1350) removes all usages of coherent buffers for USB
control-request setup-packet buffers.  There's no good reason to
reserve coherent memory for these things; control requests are hardly
ever used in large quantity (the major exception is firmware
transfers, and they aren't time-critical).  Furthermore, only seven
drivers used it.  We might as well always use streaming DMA mappings
for setup-packet buffers, and remove some extra complexity from
usbcore.

The DMA-mapping portion of hcd.c is currently in flux.  A separate
patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP
after everything else settles down.  The removal should go smoothly,
as by then nobody will be using it.

This patch makes the hidraw driver use the first Interrupt OUT endpoint for
HID transfers to the device if such an endpoint exists. This is consistent
with the behavior of the hiddev driver, and the logic is similar.

From the USB HID specification:

   The Interrupt Out pipe is optional. If a device declares an Interrupt Out
   endpoint then Output reports are transmitted by the host to the device
   through the Interrupt Out endpoint. If no Interrupt Out endpoint is
   declared then Output reports are transmitted to a device through the
   Control endpoint, using Set_Report(Output) requests.

When HIDRAW is not set, hid_hw_start() returns ENODEV as no subsystem has
claimed the magicmouse device, and probe routine bails out. Which is not what we want.

This happens because magicmouse driver is instantiating the connection to
Input subsystem itself, and since commit 28918c21 ("HID: magicmouse: fix
oops after device removal") the HID core is not registering input device
itself.

Fix this by letting HID core register the input device (so that hid_hw_start()
succeeds, as the device is claimed by at least one subsystem) and de-register
it again later before proceeding with proper input setup.

The old rejection size thresholds were too high for the 12" devices.
Larger surfaces like the Dell Studio17 exacerbated the problem since
contact size is reported on the same logical scale, making a contact
look smaller to the larger screen.

Since we have observed erroneous ghost events from these devices we
still need to filter the incoming stream.

The prior size threshold filter is still in place, though with
defaults set to leave it off.

This patch adds the two new classes of filters, those that reject
live frames before activation, and those that reject empty frames
until deactivation.  These filters are expressed in terms of a
simple state machine for clarity (I hope).

The activation filter has two components, slack and size, events
are discarded until either is satisfied.  Slack is defined as
the number of seemingly good contacts to read before accepting the
stream as valid (if the threshold is reached in the middle of a frame
the remainder of that frame is still discarded).

The deactivation filter discards empty frames until hitting a
deactivate slack.  This time measured in frames.  N-Trig devices
emit 5-8 (observed so far) empty frames at the end of multitouch
activity.  Ignoring the first few enables us to safely and gracefully
handle erroneous empty frames, thus preventing a change in the tool
state which would otherwise result in things like broken lines or
dragged objects being dropped in bad places.

Also, now that devices with different logical densities have
been observed, the aforementioned sizes are scaled from physical
to logical scales once those scales are identified.  Hopefully this
should mean that a given threshold value means the same thing across
differing devices.

Although the usbhid driver allocates its usbhid structure in the probe
routine, several critical fields in that structure don't get
initialized until usbhid_start().  However if report descriptor
parsing fails then usbhid_start() is never called.  This leads to
problems during system suspend -- the system will freeze.
