[media] DocBook: Move all media docbook stuff into its own directory

This patch addresses several issues pointed by Randy Dunlap
<rdunlap@xenotime.net> at changeset ece722c:

- In the generated index.html file, "media" is listed first, but it
  should be listed in alphabetical order, not first.

- The generated files are (hidden) in .tmpmedia/

- The link from the top-level index.html file to "media" is to
  media/index.html, but the file is actually in .tmpmedia/media/index.html

- Please build docs with and without using "O=builddir" and test that.

- Would it be possible for media to have its own Makefile instead of
  merging into this one?

Due to the way cleandocs target works, I had to rename the media DocBook
to media_api, otherwise cleandocs would remove the /media directory.

Thanks-to: Randy Dunlap <rdunlap@xenotime.net>

-controls. Further all radio devices have one tuner or modulator (these are
-discussed in <xref linkend="tuner" />) with index number zero to select
-the radio frequency and to determine if a monaural or FM stereo
-program is received/emitted. Drivers switch automatically between AM and FM
-depending on the selected frequency. The &VIDIOC-G-TUNER; or
