44b579d636 V4L/DVB (4548): Better temporal filter handling.
Adjust temporal filter if necessary. The problem with the temporal
filter is that it works well with full resolution capturing, but
not when the capture window is scaled (the filter introduces
a ghosting effect). So if the capture window changed, and there is
no updated filter value, then the filter is set depending on whether
the new window is full resolution or not.
For full resolution a setting of 8 really improves the video
quality, especially if the original video quality is suboptimal. 
Also report VBI Format in VIDIOC_LOG_STATUS, it was missing.

99eb44fe94 V4L/DVB (4259): Pass an explicit log prefix to cx2341x_log_status
A card number is not unique enough. Instead, let the caller specify the
prefix of the status messages.

8cbde94be3 V4L/DVB (4223): Add V4L2_CID_MPEG_STREAM_VBI_FMT control
V4L2_CID_MPEG_STREAM_VBI_FMT controls if and how VBI data is embedded in
an MPEG stream. Currently only one format is supported: the format designed
for the ivtv driver. This should be extended with new standard formats
(such as defined for DVB) in the future.

45ad9f8b44 V4L/DVB (4202): allow selecting CX2341x port mode
CX2341X port was always set to 'memory', but 'streaming' is also possible

ivtv uses the memory (DMA) interface with the CX2341X, while pvrusb2 and
cx88-blackbird use the streaming interface. This setting is now selectable
by the driver.

54aa9a21ca V4L/DVB (4200): Disable bitrate_mode when encoding mpeg-1.
MPEG-1 always uses CBR, so make the BITRATE_MODE control inactive.
