Make fixes and improvements - Introduce __assert_disable global - Improve strsignal() thread safety - Make system call tracing thread safe - Fix SO_RCVTIMEO / SO_SNDTIMEO on Windows - Refactor DescribeFoo() functions into one place - Fix fork() on Windows when TLS and MAP_STACK exist - Round upwards in setsockopt(SO_RCVTIMEO) on Windows - Disable futexes on OpenBSD which seem extremely broken - Implement a better kludge for monotonic time on Windows

Import C++ Standard Template Library You can now use the hardest fastest and most dangerous language there is with Cosmopolitan. So far about 75% of LLVM libcxx has been added. A few breaking changes needed to be made to help this go smoothly. - Rename nothrow to dontthrow - Rename nodiscard to dontdiscard - Add some libm functions, e.g. lgamma, nan, etc. - Change intmax_t from int128 to int64 like everything else - Introduce %jjd formatting directive for int128_t - Introduce strtoi128(), strtou128(), etc. - Rename bsrmax() to bsr128() Some of the templates that should be working currently are std::vector, std::string, std::map, std::set, std::deque, etc.

Introduce native support for MacOS ARM64 There's a new program named ape/ape-m1.c which will be used to build an embeddable binary that can load ape and elf executables. The support is mostly working so far, but still chasing down ABI issues.

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.
