- 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
