qdoc: Make qdoc handle ref qualifiers correctly

This update makes qdoc parse and record the presence of
ref qualifiers on the end of function declarations. It
unfortunately increases the number of qdoc errors
reported in QtBase, but that is because these functions
are not documented correctly. There will be another
update to qdoc to allow documenting multiple functions
with a single comment, which is needed for documenting
these ref qualified functions but also can be useful in
other contexts.
