Subject: [PATCH] * FLIM-ELS: Don't install md5-dl.el, md5-el.el, sha1-dl.el
 and sha1-el.el if the running emacs has builtin message
 digest functions.

* md5-dl.el, sha1-dl.el: Don't bind `dynamic-link' and `dynamic-call'.

* md5.el (md5-dl-module): Moved from md5-dl.el.
* sha1.el: Don't bind `sha1-string'.
