[PATCH RFC 5/6] docs: ABI: make it parse ABI/stable as ReST-compatible files

[Mauro Carvalho Chehab]

Now that the stable ABI files are compatible with ReST,
parse them without converting complex descriptions as literal
blocks nor escaping special characters.

Please notice that escaping special characters will probably
be needed at descriptions, at least for the asterisk character.
