parse-headers.rst: add an introduction to the man page
The pod2rst tool generated a man page for parse-headers.pl script, but it is better to put it into some context. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

+===========================
+Including uAPI header files
+===========================
+
+Sometimes, it is useful to include header files and C example codes in
+order to describe the userspace API and to generate cross-references
+between the code and the documentation. Adding cross-references for
+userspace API files has an additional vantage: Sphinx will generate warnings
+if a symbol is not found at the documentation. That helps to keep the
+uAPI documentation in sync with the Kernel changes.
+The :ref:`parse_headers.pl <parse_headers>` provide a way to generate such
+cross-references. It has to be called via Makefile, while building the
+documentation. Please see ``Documentation/media/Makefile`` for an example
+about how to use it inside the Kernel tree.
