Moved the *duplicate C object description* warnings for function
declarations in the nitpicky mode. In nitpick mode, you can suppress
those warnings (e.g. ioctl) with::

  nitpicky = True
  nitpick_ignore = [
      ("c:func", "ioctl"),
  ]

See Sphinx documentation for the config values for ``nitpick`` and
``nitpick_ignore`` [1].

With this change all the ".. cpp:function:: int ioctl(..)" descriptions
(found in the media book) can be migrated to ".. c:function:: int
ioctl(..)", without getting any warnings. E.g.::

  .. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp )

  .. c:function:: int ioctl( int fd, int request, struct cec_event *argp )

The main effect, is that we get those *CPP-types* back into Sphinx's C-
namespace and we need no longer to distinguish between c/cpp references,
when we refer a function like the ioctl.

[media] diff-v4l.rst: Make capabilities table fit in LaTeX

This table has several troubles:
- a duplicated "struct" on its name;
- a reference to a V4L version 1 struct that will never
  point to something (as we got rid of V4L1 API a long
  time ago);
- misses hints for LaTeX output (column size and longtable

It should be noticed that the first column of this table is
not aligned with the rest. I suspect that this is a bug at
the flat-table extension.
