Get Redbean fork() working on the New Technology Now that we have understandable system call tracing on Windows, this change rewrites many of the polyfill internals for that platform, to help things get closer to tip top shape. Support for complex forking scenarios had been in a regressed state for quite some time. Now, it works! Subsequent changes should be able to address the performance.

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.

Fix bugs in termios library and cleanup code This change fixes an issue with the tcflow() magic numbers that was causing bash to freeze up on Linux. While auditing termios polyfills, several other issues were identified with XNU/BSD compatibility. Out of an abundance of caution this change undefines as much surface area from libc/calls/struct/termios.h as possible, so that autoconf scripts are less likely to detect non-POSIX teletypewriter APIs that haven't been polyfilled by Cosmopolitan. This is a *breaking change* for your static archives in /opt/cosmos if you use the cosmocc toolchain. That's because this change disables the ioctl() undiamonding trick for code outside the monorepo, specifically because it'll lead to brittle ABI breakages like this. If you're using the cosmocc toolchain, you'll need to rebuild libraries like ncurses, readline, etc. Yes diamonds cause bloat. To work around that, consider using tcgetwinsize() instead of ioctl(TIOCGWINSZ) since it'll help you avoid pulling every single ioctl-related polyfill into the linkage. The cosmocc script was specifying -DNDEBUG for some reason. It's fixed.
