[PATCH v2 00/22] Add ABI and features docs to the Kernel documentation

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

This is a rebased version of the scripts with parse
Documentation/ABI and Documentation/feature files
and produce a ReST output. Those scripts are added to the
Kernel building system, in order to output their contents
inside the Kernel documentation.

Please notice that, as discussed, I added support at get_abi.pl
to handle ABI files as if they're compatible with ReST. Right
now, this feature can't be enabled for normal builds, as it will
cause Sphinx crashes. After getting the offending ABI files fixed,
a single line change will be enough to make it default.

a version "0" was sent back on 2017.

v1: 
  - rebased version of ABI scripts requested during KS/2019 discussions,
    with some additional changes for it to parse newer ABI files;

v2:
  - Some additional fixes and improvements to get_abi.pl script;
  - get_abi.pl script now optionally suports parsing ABI files with
    uses ReST format (by default, this is disabled);
  - Added scripts/get_feat.pl to parse Documentation/features;
  - Added SPDX headers.
