Revert "Split flymake.el into flymake-proc.el and flymake-ui.el"

In other words, re-coalesce the two files, lisp/progmodes/flymake-proc.el and lisp/progmodes/flymake-ui.el, back into a single one, lisp/progmodes/flymake.el. The changesets "Prefer HTTPS to FTP and HTTP in documentation" and "allow nil init in flymake-allowed-file-name-masks to disable flymake" are kept in place in the new lisp/progmodes/flymake.el. This reverts Git commit eb34f7f5a29e7bf62326ecb6e693f28878be28cd. Don't merge this back to master as development happening there builds upon this work.

-;;; Commentary:
-;;
-;; Flymake is a minor Emacs mode performing on-the-fly syntax checks.
-;;
-;; This file contains the most original implementation of flymake's
-;; main source of on-the-fly diagnostic info, the external syntax
-;; checker backend.
-;;
-;;; Bugs/todo:
-;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
-;;   (from http://bugs.debian.org/337339).
