Make mmap() scalable It's now possible to create thousands of thousands of sparse independent memory mappings, without any slowdown. The memory manager is better with tracking memory protection now, particularly on Windows in a precise way that can be restored during fork(). You now have the highest quality mem manager possible. It's even better than some OSes like XNU, where mmap() is implemented as an O(n) operation which means sadly things aren't much improved over there. With this change the llamafile HTTP server endpoint at /tokenize with a prompt of 50 tokens is now able to handle 2.6m r/sec

Fix bugs in cosmocc toolchain This change integrates e58abc1110b335a3341e8ad5821ad8e3880d9bb2 from https://github.com/ahgamut/musl-cross-make/ which fixes the issues we were having with our C language extension for symbolic constants. This change also performs some code cleanup and bug fixes to getaddrinfo(). It's now possible to compile projects like ncurses, readline and python without needing to patch anything upstream, except maybe a line or two. Pretty soon it should be possible to build a Linux distro on Cosmo.
