Because these lists are very long in several cases and quite varied, I opted to place them in the existing c/foo.zig files. There are many other sets of network-related constants like this to add over time across all the OSes. For now I picked these because I needed a few constants from each of these namespaces for my own project, so I tried to flesh out these namespaces completely as best I could, at least for basic sockopt purposes. Note windows has some of these already defined in ws2_32 as individual constants rather than contained in a namespacing struct. I'm not sure what to do with that in the long run (break it and namespace them?), but this doesn't change the status quo for windows in any case.
