Similar to Linux kernel approach, encapsulate some of the uglier conditional compilation into inline functions in header files. The goal is to make dwl.c more attractive to people who embrace the suckless philosophy - simple, short, hackable, and easy to understand. We want dwm users to feel comfortable here, not scare them off. Plus, if we do this right, the main dwl.c code should require only minimal changes once XWayland is no longer a necessary evil. According to `cloc`, this also brings dwl.c down below 2000 lines of non-blank, non-comment code.
