[igt-dev] [PATCH i-g-t 4/6] scripts/igt_doc.py: prepare to place TestList class on a separate file

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

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

Do some changes at the code to avoid depending on global vars and
to declare plural ancillary function as static.

Acked-by: Jari Tahvanainen <jari.tahvanainen@intel.com>
