f23df1b2a3 Comment parsing: Treat \ref as inline command
Summary:
It's basically Doxygen's version of a link and can happen anywhere
inside of a paragraph. Fixes a bogus warning about empty paragraphs when
a parameter description starts with a link.

a433e7141f [AST] Attach comment in /** doc */ typedef struct A {} B to B as well as A.
Summary:
Semantically they're the same thing, and it's important when the underlying
struct is anonymous.

There doesn't seem to be a problem attaching the same comment to multiple things
as it already happens with `/** doc */ int a, b;`

This affects an Index test but the results look better (name present, USR points
to the typedef).

c6fbfd84ad Remove spurious assertion in -Wdocumentation

6b82a75df5 [PR32667] -Wdocumentation should allow @param/@returns for fields/variables
that have a function/block pointer type

This commit improves the -Wdocumentation warning by making sure that @param and
@returns commands won't trigger warnings when used for fields, variables,
or properties whose type is a function/block pointer type. The
function/block pointer type must be specified directly with the declaration,
and when a typedef is used the warning is still emitted.

In the future we might also want to handle the std::function type as well.

Attribute filtering is currently based on a blacklist, which right now includes
all event handler attributes (they contain JavaScipt code).  It should be
switched to a whitelist, but going over all of the HTML5 spec requires a
significant amount of time.

(actOnUnknownCommand) in this case.
