This driver is really old, from devices that aren't
manufactured anymore for more than a decade.
Also, the decoder supports only MPEG2, with is not compatible
with several modern DVB streams.
It is also the only upstream driver relying on the DVB
"full-featured" API.
Some changes at the frontend drivers seem to have broken it
without anybody noticing.
Due to that, it sounds it is time to retire the driver for good.

The ttpci-eeprom is actually an independent driver that
doesn't depend on the stuff under drivers/media/pci/ttpci/.
Also, it is used by an USB driver (pctv452e).
So, move it to the common directory.

The v4l2-ctrls.c source has become much too big, so split it up
into four separate parts:
v4l2-ctrls-core.c: contains the core framework code
v4l2-ctrls-api.c: contains the uAPI interface to the framework
v4l2-ctrls-defs.c: contains the control definitions
v4l2-ctrls-request.c: contains the Request API helpers
And it adds a new v4l2-ctrls-priv.h.
No code was changed, but a number of checkpatch.pl warnings were
fixed (alignment, f == NULL -> !f, long comment block coding style,
unsigned -> unsigned int).
The copyright statements were updated as well since they were
quite out of date.

When v4l2_ctrl_request_complete() is called and there is no control
handler object found in the request, then create such an object so
that all controls at completion state can be stored and are available
to userspace.
Otherwise any attempt by userspace to read the completed request data
will fail.
If allocating the control handler object failed, then indicate that
by returning ENOMEM when attempting to get the controls from the
completed request instead of returning ENOENT.

Until now, the MPEG-2 V4L2 API was not exported as a public API,
and only defined in a private media header (media/mpeg2-ctrls.h).
After reviewing the MPEG-2 specification in detail, and reworking
the controls so they match the MPEG-2 semantics properly,
we can consider it ready.

The Hantro and Cedrus drivers work in frame-mode,
meaning they expect all the slices in a picture (either frame
or field structure) to be passed in each OUTPUT buffer.
These two are the only V4L2 MPEG-2 stateless decoders currently
supported. Given the VA-API drivers also work per-frame,
coalescing all the MPEG-2 slices in a buffer before the decoding
operation, it makes sense to not expect slice-mode drivers and
therefore remove V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMS.
This is done to avoid carrying an unused interface. If needed,
this control can be added without breaking backwards compatibility.
Note that this would mean introducing a enumerator control to
specify the decoding mode (see V4L2_CID_STATELESS_H264_DECODE_MODE).

Typically, bitstreams are composed of a sequence header,
followed by a number of picture header and picture coding extension
headers. Each picture can be composed of a number of slices.
Let's split the MPEG-2 uAPI to follow these semantics more closely,
allowing more usage flexibility. Having these controls split up
allows applications to set a sequence control at the beginning
of a sequence, and then set a picture control for each frame.
While here add padding fields where needed, and document
the uAPI header thoroughly.
Note that the V4L2_CTRL_TYPE_{} defines had to be moved because
it clashes with existing ones. This is not really an issue
since they will be re-defined when the controls are moved
out of staging.

Our current MPEG-2 uAPI uses 1-byte fields for MPEG-2
boolean syntax elements. Clean these by adding a 'flags'
field and flag macro for each boolean syntax element.
A follow-up change will refactor this uAPI so we don't need
to add padding fields just yet.

As stated in the MPEG-2 specification, section 6.3.7 "Quant matrix
extension":
Each quantisation matrix has a default set of values. When a
sequence_header_code is decoded all matrices shall be reset to
their default values. User defined matrices may be downloaded
and this can occur in a sequence_header() or in a
quant_matrix_extension().
The load_intra_quantiser_matrix syntax elements are transmitted
in the bitstream headers, signalling that a quantisation matrix
needs to be loaded and used for pictures transmitted afterwards
(until the matrices are reset).
This "load" semantics are implemented in the V4L2 interface
without the need of any "load" flags: passing the control
is effectively a load.
Therefore, rework the V4L2_CID_MPEG_VIDEO_MPEG2_QUANTISATION
semantics to match the MPEG-2 semantics. Quantisation matrices
values are now initialized by the V4L2 control core to their
reset default value, and applications are expected to reset
their values as specified.
The quantisation control is therefore optional, and used to
load bitstream-defined values in the quantisation matrices.

I came across a randconfig build failure from one driver
that only depends on CONFIG_USB_ARCH_HAS_HCD but fails when
built without CONFIG_USB:
ld: drivers/media/rc/ir_toy.o: in function `irtoy_disconnect':
ir_toy.c:(.text+0x24): undefined reference to `usb_kill_urb'
ld: ir_toy.c:(.text+0x2c): undefined reference to `usb_free_urb'
ld: ir_toy.c:(.text+0x34): undefined reference to `usb_kill_urb'
ld: ir_toy.c:(.text+0x3c): undefined reference to `usb_free_urb'
Upon a closer look, I find that a lot of the other drivers
'select USB' rather than stating 'depends on USB' as is common
for most subsystems. I also find that all except one driver
have an extra 'depends on RC_CORE' that is already implied by
the top-level 'if RC_CORE' check.
Clean up both by reducing the dependencies to the required set.
