* lisp/subr.el (macrop): New function.

(text-clone--maintaining): New var.
(text-clone--maintain): Rename from text-clone-maintain.  Use it
instead of inhibit-modification-hooks.

* lisp/emacs-lisp/nadvice.el (advice--normalize): For aliases to macros, use
a proxy, so as handle autoloads and redefinitions of the target.
(advice--defalias-fset, advice-remove): Use advice--symbol-function.

* lisp/emacs-lisp/pcase.el (pcase-mutually-exclusive-predicates):
Remove bogus (arrayp . stringp) pair.  Add entries for `vectorp'.
(pcase--mutually-exclusive-p): New function.
(pcase--split-consp): Use it.
(pcase--split-pred): Use it.  Optimize the case where `pat' is a qpat
mutually exclusive with the current predicate.

* test/automated/advice-tests.el (advice-tests-nadvice): Test removal
before definition.
(advice-tests-macroaliases): New test.

* lisp/emacs-lisp/edebug.el (edebug-lookup-function): Remove function.
(edebug-macrop): Remove.  Use `macrop' instead.
* lisp/emacs-lisp/advice.el (ad-subr-p): Remove.  Use `subrp' instead.
(ad-macro-p):
* lisp/eshell/esh-cmd.el (eshell-macrop):
* lisp/apropos.el (apropos-macrop): Remove.  Use `macrop' instead.
