Lisp: add def{struct,type,method,class,generic,parameter} kinds and definer field

[masatake]

Close #4120.

• man pages for EmacsLisp and Lisp must be added.
• introduce a data structure representing the difference between Lisp and EmacsLisp.
• L_isdef and L_isquote should be unified.

Looks good to me!

Sorry for being so chaotic, but can you also add defparameter as the variable definer? It's the same as defvar in regards to parsing and the type of entities it creates—variables.

I added the parameter/p kind. "definer:" field is for language objects tagged as unknown/Y.

I added the parameter/p kind.

Semantically, defparameter defines variables, as there are no parameter objects in Common Lisp. Can you use v instead?

Ah, okay then.

Unifying variables and parameters is the job of client tools.
ctags should provide raw information to the client tools.

So be it then 👌
