The dvb-pll sleep function could only send a 2-byte sequence to the PLL.
This isn't enough in some cases, for example fmd1216me will need to send
a 4-byte command to set both BB and AB to the correct values.

Instead of using a fake band with a frequency of 0 to store the sleep
data (which has room for only two bytes), the new sleep function works
like the init function.  A new pointer is added to the pll description,
and when non-NULL points to a buffer with the length and data to send.

The IF frequency was specified for each band, but it's not something that
changes from band to band.  None of the tuner definitions had a different
IF frequency (called offset) from one band to another.

Some PLLs had one half the step size added to the offset, so that the
divisor would be rounded to the nearest integer.  Some didn't and so
would always be rounded down.

This makes dvb-pll round to the nearest when calculating the divisor,
without the offset needing to be fudged.  PLLs that had a fudged offset
have the offset changed to be just the IF frequency.
The satellite PLL dvb_pll_philips_sd1878_tda8261 was rounding up for some
reason, and I've kept it that way.

In addition, frequencies that were rounded to the nearest kHz are
extended to full Hz resolution.  One sixth MHz step sizes that were
listed as 166,666 Hz are changed to 166,667 Hz, which is slightly closer.

PLLs that were already rounding:
dvb_pll_tda665x, offset was 36 1/6 (to nearest kHz) + step/2
dvb_pll_fmd1216me, offset was 36 1/8 (to two digits) + step/2
dvb_pll_thomson_fe6600, offset was 36 1/8 (to two digits) + step/2
dvb_pll_env57h1xd5, offset was 36 1/8 + step

Note that the last PLL, dvb_pll_env57h1xd5, appears to have had a bug in
the offset.  Rather than adding stepsize/2, it was adding a full
stepsize.  The PLL definition originally came from the dibusb driver,
which used 36 1/8 + step/2.  The change to 36 1/8 + step was probably a
mistake added when the tuner was converted to dvb-pll.

Change a 00 to just 0
Detect zero-length I2C messages and return not supported.  I think I know
how to send one, but the problem is getting the slave's ack.  The only
point of a zero-length message is for probing; too see if the slave will
ack its address.  Since we don't know how to get the ack, we can't
support zero-length messages in a useful way, so it's probably best to
just return not supported for them.

The I2C xfer function should now handle more types of I2C transactions

being executed incorrectly.  Multi-byte reads were not being done

Once the devices have been registered anyone can start changing the inputs or
TV standard before they have been initialized by the driver. This leads to
cases were the input is changed in an udev rule, but after that rule is
triggered the tail-end of the ivtv driver initialization can override
that by selecting the tuner input.
The correct sequence is to first setup the input, initial frequency and TV
standard before finally registering the video devices. This prevents any
udev rules from being triggered prematurely.
