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.

Mint APE Loader v1.4 This change also incorporates more bug fixes and improvements to a wide variety of small things. For example this fixes #860 so Windows console doesn't get corrupted after exit. An system stack memory map issue with aarch64 has been fixed. We no longer use O_NONBLOCK on AF_UNIX sockets. Crash reports on Arm64 will now demangle C++ symbols, even when c++filt isn't available. Most importantly the Apple M1 version of APE Loader is brought up to date by this change. A prebuilt unsigned binary for it is being included in build/bootstrap/. One more thing: retrieving the term dimensions under --strace was causing the stack to become corrupted and now that's been solved too. PSS: We're now including an ELF PT_NOTE for APE in the binaries we build, that has the APE Loader version.
