This commit does two things: - Renames def-advice! to defadvice!, in the spirit of naming convenience macros after the function/macro they enhance or replace. - Correct the names of advice functions to indicate visibility and intent. A public advice function like doom-set-jump-a is meant to be used elsewhere. A private one like +dired--cleanup-header-line-a shouldn't -- it likely won't work anywhere but the function(s) it was made to advise.
