If rf_cal_on_startup is enabled in the structure passed into
tda18271_attach, and the cal module option isn't disabled, then we
should run the initialization and calibration procedures during the
tda18271_attach function call, regardless of how many instances of the
driver have been attached.  If the device is already calibrated, the
driver will detect that and will only calibrate again if necessary.

There is already an option for sending 16 byte chunks rather that writing
39 bytes all at once during the tuner's initialization.  Some i2c buses
can't send 16 bytes at once, so create an option for sending 8 byte chunks.

Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The gscpa core was not resubmitting URB's when the URB status was an error,
this means we will loose URB's (potentially all stopping the stream) in
case of sporadic USB issues. I've seen this with an Aiptek stv0680 based
PenCam connected through an USB 2.0 hub.

gspca w9968cf: Add support for JPEG compression, this enables much higher
framerates at 320x240 / 352x288 and also allows for 640x480 mode for
cams which can do this. The w9968cf uses planar JPEG, which libv4l until
now did not support, so this requires atleast version 0.6.3 of libv4l.

And something important I forgot to mention in my earlier w9968cf commits:

This patch adds support to gspca for the Winbond W9967CF and W9968CF
camera's. This is mostly a port of the existing v4l1 driver to gspca
(making it v4l2). But this also features fixes to the bitbanging i2c code
(send a nack not an ack after reading the last byte of a transfer), which
gets rid of the weird errors which were being seen there, and of
the smbus_refresh() hack to get around these errors.

Also the vstart settings have been tweaked to work with different
frequency filter settings.

If the I2C device provides an interrupt it is registered and the
standard
is updated via interrupts rather than polling.

Since I2C communication is needed, the interrupt handler fires off a
work which will check the new standard, and store it in the internal
structure.

To handle mutual exclusion a mutex is introduced.
