Work around subrs that block EXWM; other minor fixes
Some subrs (e.g. x-file-dialog) create X windows and block the execution of EXWM, so they won't work normally. This commit partly fixes this issue by invoking them in a subordinate Emacs instance and trying to fetch the result back. * exwm.el (exwm-blocking-subrs): New variable for specify such subrs. * exwm.el (exwm-enable, exwm--server-name, exwm--server-stop) (exwm--server-eval-at): The implementation. * exwm-core.el: * exwm-floating.el: * exwm-layout.el: * exwm-manage.el: * exwm-randr.el: Evaluate constants at compile-time. * README.md: Renamed from README.org to make the 'Commentary:' section used by GNU ELPA instead. * exwm.el: Depends on XELB version 0.3.
