The naming of the media/rds.h header suggested that it was a generic
RDS header, when in fact it is just a saa6588 module API that is
internal to the kernel.
Rename the header and the struct and defines in it to make this clear.
Also removed the header include in radio-si470x.h (not used anymore)
and from ioctl-number.txt (it's internal to the kernel and never called
from userspace).

Some comments:
1. Everything initialize properly except radio.
2. All analog inputs (TV, composite, S-Video) are tested by myself in several
TV norms (SECAM-D, PAL, NTSC), everything work fine.
So the patch adds general support/detection of the card with working analog
part, DVB part is not supported for now.

A Hauppauge HVR 4000 is used on a School On Internet Asia (SOI Asia)
project in order to carry IP traffic over ULE. However, there is an
issue with high latency jitter.
My boss, Husni, identified the problem and provided a patch for it.
The default buffer size of 32 TS frames on cx88 causes the high latency,
so our deployment changes that to 6 TS frames. This patch made the
buffer size tunable, while keeping the default buffer size of 32 TS
frames unchanged.

dabusb driver were conceived as an experimental driver for a test
device. The driver never supported any shipped product, and, while
there were some updates on it in 2003, for an ancient product,
those changes were never submitted upstream.
Also, there's no DocBook for its API, nor any upstream discussion.
So, better to remove it, on .39. If later needed, we may rescue it
from git logs. For now, let's move it to staging.

The check for status errors is now before the check for len. That's
ok. However, the error printk's for the status error prints the URB
length. This generates this error:
drivers/media/video/gspca/gspca.c: In function ‘fill_frame’:
drivers/media/video/gspca/gspca.c:305:9: warning: ‘len’ may be used uninitialized in this function
The fix is as simple as moving the len init to happen before the checks.

ivtv_write_vbi() is used for both VBI data that came from the
driver internally and VBI data that came from the user. However,
it did not use copy_from_user() for reading the VBI data from the
user buffers.
This change adds a new version of the function,
ivtv_write_vbi_from_user(), that uses copy_from_user() to read the VBI
data provided via user buffers.
This should resolve a sparse build warning reported by Dave Gilbert.
