scripts: get_abi.pl: change script to allow parsing in ReST mode
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.
