Split Flymake into flymake.el into flymake-proc.el (again!)
After deciding that this work would continue on master only, which
caused two commits named
Revert "Split flymake.el into flymake-proc.el and flymake-ui.el"
and
Revert "Add flymake-backends defcustom"
to be added to the emacs-26 branch, further discussion reversed that
decision.
See:
https://lists.gnu.org/archive/html/emacs-devel/2017-09/msg01020.html
https://lists.gnu.org/archive/html/emacs-devel/2017-09/msg01030.html
This means that those two commits MUST be merged to master AFTER ALL.
flymke-proc.el contains the main syntax-checking backend, while
flymake.el keeps mostly the UI part.
* lisp/progmodes/flymake-proc.el: New file. Require flymake.
* lisp/progmodes/flymake.el: Require flymake-proc.el at the end.
