Script to build the media documentation as if it were a single book

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Hi,

In order for the media documentation to match the upstream rules, it was
split for 5.7 into 3 different books. This makes total sense for upstream.

Yet, people may still want to see it as a single book. So, I wrote a small
script (see enclosed) that does that.

I'm using a variant of it to produce the documentation output available at:
	https://linuxtv.org/docs.php

(with is updated once per day).

Perhaps others could find this script useful. This script is under GPLv2,
but please notice that some media docs are under GFDL licensing.

Thanks,
Mauro
