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  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.
