- This commit mints a new release of APE Loader v1.2 which supports loading ELF programs with a non-contiguous virtual address layout even though we've never been able to take advantage of it, due to how `objcopy -SO binary` fills any holes left by PT_LOAD. This'll change soon, since we'll have a new way of creating APE binaries. - The undiamonding trick with our ioctl() implementation is removed since POSIX has been killing ioctl() for years and they've done a much better job. One problem it resolves, is that ioctl(FIONREAD) wasn't working earlier and that caused issues when building Emacs
