The references there are only for DVB. Add missing references for
ATSC and ISDB standards.

89aba6adc1 media: dvb/intro: use the term Digital TV to refer to the system
On several places at the introduction, a digital TV board and its
kernel support is called as DVB. The reason is simple: by the
time the document was written, there were no other digital TV
standards :-)

Modernize the specs by referring to them as Digital TV.

1e1d9c9679 media: dvbproperty.rst: improve notes about legacy frontend calls
The description of the DVBv5 API was written a long time ago,
where the API was still new, and there were not apps using it.

Now that the API is stable and used by new applications, clarify
that DVBv3 calls should not be used and why.

3430b8e9aa media: frontend.rst: fix supported delivery systems
The introduction for the frontend chapter is not quite
correct:
  - it tells that it supports only three types of
    delivery systems, in opposite to three *groups*;
  - It adds ISDB-C to the list of supported systems,
    but, this is not true.

Fix it.

e5707c9abf media: dvb/intro.rst: Use verbatim font where needed
The device numbering for DVB uses "M" and "N" as vars for the

While here, remove an extra space after quotation marks.

70b074df4e media: fix pdf build with Spinx 1.6
Sphinx 1.6 generates some LaTeX code before each table,
starting its own environment before calling tabulary,
apparently to improve table layout.

The problem is that such environment is incompatible with
adjustbox. While, in thesis, it should be possible to override
it or to redefine tabulary, I was unable to produce such patch.

Also, that would likely break on some future Sphinx version.

So, instead, let's just change the font size on bigger tables,
in order for them to fit into the page size. That is not as
good as adjustbox, and require some manual work, but it should
be less sensitive to Sphinx changes.

While here, adjust a few other tables whose text is exceeding
the cell boundaries.

The CEC_EVENT_PIN_LOW/HIGH defines and the cec_queue_pin_event() function
did not specify that these were about CEC pin events.

Since in the future there will also be HPD pin events it is wise to rename

cec_queue_pin_cec_event() now before these become part of the ABI.

5dcd7c66bc media: media/doc: rename and reorder pixfmt files
After the DocBook conversion a number of pixfmt description files just
had a number in the filename (pix-fmt-004, 006, etc) which was not very
descriptive.

Rename them.

Note that pixfmt-008.rst was folded into colorspaces-details.rst, so
that file is deleted. It's easier to maintain that way.

Also moved the colorspace sections to the end of the chapter. The old
order was weird: the "Standard Image Formats" section (an intro into
pixel formats) was followed by the colorspace sections instead of the
pixel format descriptions.

Moving it to the end resolved that issue.

Sending patches with SVG files via e-mail has a drawback: line

So, use this small Perl script to limit columns size to ~900.

 "Media updates for v4.12-rc1:

   - new driver to support mediatek jpeg in hardware codec

   - rc-lirc, s5p-cec and st-cec staging drivers got promoted

   - hardware histogram support for vsp1 driver

   - added Virtual Media Controller driver, to make easier to test the
     media controller

   - added a new CEC driver (rainshadow-cec)

   - removed two staging LIRC drivers for obscure hardware that are too
     obsolete

   - added support for Intel SR300 Depth camera

   - some improvements at CEC and RC core

   - lots of driver cleanups, improvements all over the tree

  With this series, we're finally getting rid of the LIRC staging
  driver. There's just one left (lirc_zilog), with require more care,
  as part of its functionality (IR RX) is already provided by another
  driver. Work in progress to convert it on the proper way"

242b0c4cc9 [media] pixfmt-meta-vsp1-hgo.rst: remove spurious '-'
Remove spurious '-' in the VSP1 hgo table.

This resulted in a weird dot character that also caused
the row to be double-height.

We used to have it on other tables, but we got rid of them
on changeset 8ed29e302d ("[media] subdev-formats.rst: remove
spurious '-'").

8ed29e302d [media] subdev-formats.rst: remove spurious '-'
Remove spurious duplicate '-' in the Bayer Formats description. This resulted in a
weird dot character that also caused the row to be double-height.

The - character was probably used originally as indicator of an unused bit, but as the
number of columns was increased it was never used for the new columns.

Other tables do not use '-' either, so just remove it.
