Currently if none of the requested logical addresses can be claimed, the
framework will fall back to the Unregistered logical address.
Add a flag to enable this explicitly. By default it will just go back to
the unconfigured state.
Usually Unregistered is not something you want since the functionality is
very limited. Unless the application has support for this, it will fail
to work correctly. So require that the application explicitly requests
this.

Now that the only remaining chapters at v4l2-framework are
the introduction ones, let' s rename the file.

Move the v4l2 clocks stuff from v4l2-framework to a separate
file and adds an attention that came from the v4l2-clk.h.
Note: as this is meant to be a temporary kAPI, and it is
used only by two drivers (soc_camera and em28xx), where
the first one is in deprecation process, it probably not
a worth effort to document its header.

Move the v4l2 event-specific text from v4l2-framework.rst
to v4l2-event.rst. That helps to keep the text together with
the functions it describes, and makes easier to identify
documentation gaps.

The kAPI, v4l-drivers and dvb-drivers never used the
GNU FDL license. The addition of such license header were
just due to copy-and-paste. So, let's fix it.
As the media_kapi were part of device-drivers.tmp, it is
under GPL v2+.
The other two books is an agregation of files without any
license explicitly specified. So, they're all bound to the
Kernel's COPYING license. So, they're GPL v2 only.

The uAPI book has 5 parts, but they lost numeration after
conversion to rst. Manually number those parts, and make
the main index with 1 depth, to only show the parts and
the annexes.
At each part, use :maxwidth: 5, in order to show a more
complete index.

Sphinx is really evil when an older version finds an extra
attribute for the :toctree: tag: it simply ignores everything
and produce documents without any chapter inside!
As we're now using tags available only on Sphinx 1.4.x, we
need to use some creative ways to add a title before the
table of contents. Do that by using a css class.
