[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>

-    <para>To query the attributes of an entity, applications set the id field
-    of a &media-entity-desc; structure and call the MEDIA_IOC_ENUM_ENTITIES
-    ioctl with a pointer to this structure. The driver fills the rest of the
-    structure or returns an &EINVAL; when the id is invalid.</para>
-    <para>Entities can be enumerated by or'ing the id with the
-    <constant>MEDIA_ENT_ID_FLAG_NEXT</constant> flag. The driver will return
-    information about the entity with the smallest id strictly larger than the
-    requested one ('next entity'), or the &EINVAL; if there is none.</para>
-    <para>Entity IDs can be non-contiguous. Applications must
-    <emphasis>not</emphasis> try to enumerate entities by calling
-    MEDIA_IOC_ENUM_ENTITIES with increasing id's until they get an error.</para>
