cx25840 / pvrusb2: Experimental support for Closed Captions

From: Steven Toth

*** Experimental: These need major cleanup before consideration for upstream ***

Some NTSC specific Closed Captions patches for the CX25840 and the HVR1950.
These are highly experimental and are known to break certain features for
PAL. Completely untested outside of NTSC. Kudos to FredR for helping out.

Testing with mplayer (Ubuntu x64 9.10) using:
> v4l2-ctl -d /dev/video0 --set-freq 163.25
> mplayer -subcc -cache 2048 /dev/video0

Known issues:
1. Various checkpatch coding style violations.

2. Captioning is known NOT to work during the first test of mplayer, but
subsequent tests work reliably.

V4L/DVB: dvb-core: Fix ULE decapsulation bug

Fix ULE decapsulation bug when less than 4 bytes of ULE SNDU is packed
into the remaining bytes of a MPEG2-TS frame

ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
code has a bug that incorrectly treats ULE SNDU packed into the
remaining 2 or 3 bytes of a MPEG2-TS frame as having invalid pointer
field on the subsequent MPEG2-TS frame.

V4L/DVB: video/saa7134: change dprintk() to i2cdprintk()

The problem is that dprintk() dereferences "dev" which is null here.
The i2cdprintk() uses "ir" so that's OK.

Also Jean Delvare pointed out a typo in the comment so we may as well
fix that.

V4L/DVB: drivers/media: Eliminate a NULL pointer dereference

In each case, the print involves dereferencing a value that is NULL or is
near NULL.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

//
@r exists@
expression E,E1;
identifier f;
statement S1,S2,S3;
@@

if ((E == NULL && ...) || ...)
{
... when != if (...) S1 else S2
when != E = E1
* E->f
... when any
return ...;
}
else S3
//
