This commit mostly duplicates the wlr_log functions, although with a sway_* prefix. (This is very similar to PR #2009.) However, the logging function no longer needs to be replaceable, so sway_log_init's second argument is used to set the exit callback for sway_abort. wlr_log_init is still invoked in sway/main.c This commit makes it easier to remove the wlroots dependency for the helper programs swaymsg, swaybg, swaybar, and swaynag.
