Replace uses of defadvice with advice-add

This either requires a dependency on the `nadvice` package,
or bumping the minimum Emacs version to 24.4.  I went with
the `nadvice` package, but maybe bumping up to 24.4 would be better.

* evil.el: Require `nadvice`.

* evil-core.el (evil--advices): New var.
(evil-mode): Use it instead of `ad-dis/enable`.
(evil--advice-add): New function.
(set-window-buffer, select-window, toggle-input-method, use-global-map):
* evil-search.el (isearch-message-prefix, isearch-delete-char)
(isearch-lazy-highlight-search):
* evil-integration.el (keyboard-quit, wdired-change-to-dired-mode)
(show-paren-function, quail-show-key, describe-char, ace-jump-done):
Use `(evil--)advice-add` instead of `defadvice`.
(preceding-sexp, pp-last-sexp): Remove old code for when `advice-add`
is not available.

* evil-repeat.el (evil--read-key-sequence-advice): Adapt to use in
`advice-add`.
(read-key-sequence, read-key-sequence-vector): Use `advice-add`.

* evil-keybindings.el (elp-results): Use `advice-add` and move outside
of `eval-after-load`.
