doc-rst: moved *duplicate* warnings to nitpicky mode
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.
