docs: automarkup.py: Skip C reserved words when cross-referencing
With the transition to Sphinx 3, new warnings were caused by
automarkup, exposing bugs in the name matching.
When automarkup parsed a text like "struct struct" in the documentation,
it tried to cross-reference to a "struct" symbol, which is recognized as
a C reserved word by Sphinx 3, generating a warning.
Add some C reserved words (only the ones that were causing warnings) to
a list and skip them while trying to cross-reference.
