V4L/DVB (6316): Change list_for_each+list_entry to list_for_each_entry

The rest of V4L files.

There is one list_for_each+list_entry in cpia_pp.c that
wasn't changed because it expects the loop iterator to remain NULL if
the list is empty.

A bug in vivi is fixed; the 'safe' version needs to be used because the loop
deletes the list entries.

Simplify a second loop in vivi and get rid if an un-used variable in that loop.

- Controls memory allocations

Scatter/Gather needs. The original approach can't even work for those
video capture hardware that don't support scatter/gather.

I did one approach to make it more generic. While the approach worked
fine for vivi driver, it were not generic enough to handle USB needs.

This patch creates two different modules, one containing the generic

V4L/DVB (6235): cafe_ccic: default to allocating DMA buffers at probe time

By default, we allocate DMA buffers when actually reading from the video
capture device.  On a system with 128MB or 256MB of ram, it's very easy
for that memory to quickly become fragmented.  We've had users report
having 30+MB of memory free, but the cafe_ccic driver is still unable to
allocate DMA buffers.

Our workaround has been to make use of the 'alloc_bufs_at_load' parameter
to allocate DMA buffers during device probing.  This patch makes DMA
buffer allocation happen during device probe by default, and changes
the parameter to 'alloc_bufs_at_read'.  The camera hardware is there,
if the cafe_ccic driver is enabled/loaded it should do its best to ensure
that the camera is actually usable; delaying DMA buffer allocation
saves an insignicant amount of memory, and causes the driver to be much
less useful.

V4L/DVB (6210): pvrusb2: Do a far better job at setting the default initial video standard

The v4l tveeprom logic tells us what video standards are supported by
the hardware, however it doesn't directly tell us what should be the
preferred initial standard.  For example "NTSC/NTSC-J" devices are
reported by tveeprom as support NTSC-M and PAL-M, and while that might
be true, in the vast majority of cases NTSC-M is really what the user
is going to want.  However the driver previously just arbitrarily
picked the "lowest numbered" standard as the initial default, which in
that case would have been PAL-M.  (And making matters more confusing -
this only caused real problems on 24xxx devices because the saa7115 on
29xxx seems to autodetect the right answer anyway.)  This change
implements an algorithm that uses the set of "supported" standards as
a hint to decide on the initial standard.  This algorithm ONLY comes
into play if the driver isn't specifically told what to do; said
another way - the user can always still change the standard via the
sysfs interface, via the usual V4L methods, or even specified as a
module parameter.  The idea here is only to pick a better starting
point if the user (or app) doesn't otherwise do something to set the
standard; otherwise this change has no real impact.
