doc-rst: Remove the media docbook

Now that all media documentation was converted to Sphinx, we
should get rid of the old DocBook one, as we don't want people
to submit patches against the old stuff.

-    <para>These ioctls control an audio/video (usually MPEG-) decoder.
-<constant>VIDIOC_DECODER_CMD</constant> sends a command to the
-decoder, <constant>VIDIOC_TRY_DECODER_CMD</constant> can be used to
-try a command without actually executing it. To send a command applications
-must initialize all fields of a &v4l2-decoder-cmd; and call
-<constant>VIDIOC_DECODER_CMD</constant> or <constant>VIDIOC_TRY_DECODER_CMD</constant>
-with a pointer to this structure.</para>
-
-    <para>The <structfield>cmd</structfield> field must contain the
-command code. Some commands use the <structfield>flags</structfield> field for
-additional information.
-</para>
-
-    <para>A <function>write</function>() or &VIDIOC-STREAMON; call sends an implicit
-START command to the decoder if it has not been started yet.
-</para>
-
-    <para>A <function>close</function>() or &VIDIOC-STREAMOFF; call of a streaming
-file descriptor sends an implicit immediate STOP command to the decoder, and all
-buffered data is discarded.</para>
-
-    <para>These ioctls are optional, not all drivers may support
-them. They were introduced in Linux 3.3.</para>

-speed. Speeds -1, 0 and 1 have special meanings: speed 0 is shorthand for 1000
-(normal playback). A speed of 1 steps just one frame forward, a speed of -1 steps
-just one frame back.

-if the decoder operates on full GOPs (<wordasword>Group Of Pictures</wordasword>).
-This is usually the case for reverse playback: the decoder needs full GOPs, which
-it can then play in reverse order. So to implement reverse playback the application
-must feed the decoder the last GOP in the video file, then the GOP before that, etc. etc.

-and all frames are ready to be dequeued and will set the
-<constant>V4L2_BUF_FLAG_LAST</constant> buffer flag on the last buffer of the
-capture queue to indicate there will be no new buffers produced to dequeue. This
-buffer may be empty, indicated by the driver setting the
-<structfield>bytesused</structfield> field to 0. Once the
-<constant>V4L2_BUF_FLAG_LAST</constant> flag was set, the
-<link linkend="vidioc-qbuf">VIDIOC_DQBUF</link> ioctl will not block anymore,

-If <constant>V4L2_DEC_CMD_STOP_IMMEDIATELY</constant> is set, then the decoder
-stops immediately (ignoring the <structfield>pts</structfield> value), otherwise it
-will keep decoding until timestamp >= pts or until the last of the pending data from
