Right now, several ABI files won't parse as ReST, as they
contain severe violations to the spec, with makes the script
to crash.
So, the code has a sanity logic with escapes bad code and
cleans tags that can cause Sphinx to crash.
Add support for disabling this mode.
Right now, as enabling rst-mode causes crash, it is disabled
by default.
