According to the v4l2 spec, very old MPEG index entries needs to be discarded
in favor of newer index entries. This change ensures the firmware always has
buffers for index entries at the expense of the oldest unread buffers.

This change starts the IDX stream along with the MPG stream as an internal
use (only) stream much like the VBI stream can be started as an internal use
stream for inserting sliced VBI packets.
The IDX stream is not started automatically with an MPEG strem if the IDX
stream is disabled (no buffers allocated) or if sliced VBI insertion is being
performed by the cx18 driver. The cx18 driver doing sliced VBI insertion
makes the offsets in the IDX stream inaccurate for the final MPEG stream
presented to user space. Since fixing the IDX offsets ourselves is not easy
and we cannot easily do what ivtv does to fix the offsets, we'll make sliced
VBI insertion and MPEG Index capture mutually exclusive for now.

This change allows the IDX stream to be started and stopped as any other
stream even though it has no associated device node. This is needed for
cx18 driver internal use.
Also always tell the CX23418 to generate index entries when an analog capture
starts and the IDX stream has had buffers allocated (i.e. is enabled).

Update the module options related to INDEX stream buffer allocation. A single
CX2341[5678] index entry is only 24 bytes. Large buffers for the IDX stream
will prevent the CX23418 from transferring index data over at all. Buffers
of around 1.5 kB or 64 index entries seem to be just fine. We'll default to
63 buffers/MDLs as that is the firmware limit per stream and IDX stream buffers
are not high rate. There is no reason on earth to allocate the previous 1 MB
default of buffer space for the IDX stream.
This is in anticipation of implementing the G_ENC_INDEX ioctl() in the cx18
driver.

After taking a look at the driver's history and doing some tests with
DVB and ISDB-T, it was noticed that the stats were incomplete, for
ISDB-T, and weren't working for DVB.
Fixed the code and added a debug code to print the complete stats at
dmesg. This debug is useful to improve the stats of this driver.

Based on a patch originally written by Michael Krufky <mkrufky@linuxtv.org>
for a preliminar S2API spec.
The patch were ported to the S2API and had the ISDB-T API additions to
honor the auto mode, while keep allowing manual tuning.
Tested with both the original dvb-apps and the new dvb-apps-isdbt scan,
that uses a different channel.conf and uses S2API with ISDB-T extensions.

The realtime clock provided by do_gettimeofday() is affected by time
jumps caused by NTP or DST. Furthermore, preliminary investigation
showed that SMP systems the realtime clock is based on the CPU TSC,
and those could get slightly out of sync, resulting in jitter in the
timestamps depending on which processor handles the USB interrupts.
Instead of the realtime clock, use a monotonic high resolution clock to
timestamp the buffer. As this could in theory introduce a regression
with some userspace applications expecting a realtime clock timestamp,
add a module parameter to switch back to the realtime clock.
Thanks to Paulo Assis for pointing out and investigating the issue.
