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.
