testing: Make all files use `lexical-binding` Mainly, add the corresponding cookie, but also add various `require`s so that the compiler knows which vars should be trated as dynbound. This does not fix all the warnings, but does try to eliminate all those about "unused" variables. For the variables truly unused, the patch usually adds an underscore to their name to silence the warning. Some of the fixes affect files which already used `lexical-binding`. Not sure why the test worked before: maybe because the tests were run without compiling them first (which could cause some of the missing `require`d packages to be autoloaded before we got to the problematic code, thus hiding the problem)? I found some suspicious code, for which I added FIXMEs. There are also a few changes to the main files. * lisp/org-protocol.el (org-protocol-check-filename-for-protocol): Don't call `server-edit` if it's not yet defined. [ Needed to get the tests to pass. ] * lisp/ob-core.el (org-babel-temporary-directory) (org-babel-temporary-stable-directory): Always define (and use nil if we don't want to create a directory for it). Simplify the code based on the fact that (defvar V E) only evaluates E if V is not yet `boundp`. (org-babel-temp-file, org-babel-temp-stable-file) (org-babel-remove-temporary-directory) (org-babel-remove-temporary-stable-directory): Adjust accordingly. * lisp/org.el (org-log-beginning): Add FIXME. * testing/org-test.el: Require `org` and `org-id`. (org-id-locations-file): Don't `defconst` it. (org-test-at-id, org-test-in-example-file, org-test-at-marker) (org-test-with-temp-text, org-test-with-temp-text-in-file): Move edebug specs into `declare` (and simplify them). (org-test-with-tramp-remote-dir--worker): Declare dynbound tramp vars. (org--compile-when): Fix quoting of `exp`. (org-test-load): Tweak regexps. * testing/org-batch-test-init.el: Tweak regexp, remove dead code and add a FIXME about it. * testing/lisp/test-ox.el: Require `ox` instead of erroring out if it's not already loaded.
