[igt-dev] [PATCH i-g-t v2 02/19] scripts/igt_doc.py: add JSON file output

From: Mauro Carvalho Chehab <mchehab at kernel.org>

At least for debugging purposes, it is interesting to see how the
script is parsing the input files and expanding wildcards on a more
condensed way. So, add support to output the dictionary contents
into a json file.
