- 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

/**
* Performs special i/o operation on file descriptor.
*
* @param request can be any of:
*
* - `FIONREAD` takes an `int *` and returns how many bytes of input
* are available on a terminal or socket, waiting to be read. On
* Windows this currently won't work for console file descriptors.
*
* - `TIOCGWINSZ` populates `struct winsize *` with the dimensions
* of your teletypewriter. It's an alias for tcgetwinsize().
*
* - `TIOCSWINSZ` with the dimensions of your teletypewriter to
* `struct winsize *`. It's an alias for tcsetwinsize().
*
* - `TIOCOUTQ` takes an `int *` and returns the number of bytes in
* the terminal's output buffer. Only available on UNIX.
*
* - `TIOCSTI` takes a `const char *` and may be used to fake input
* to a tty. This API isn't available on OpenBSD. Only available
* on UNIX.
*
* - `TIOCNOTTY` takes an `int tty_fd` arg and makes it the
* controlling terminal of the calling process, which should have
* called setsid() beforehand.
*
* - `TIOCNOTTY` to give up the controlling terminal. Only available
* on UNIX.
*
* - `TIOCNXCL` to give up exclusive mode on terminal. Only
* available on UNIX.
*
* - `FIOCLEX` sets the `O_CLOEXEC` state (no arg) noting that this
* polyfill may be removed in the future, and code should migrate
* to the equivalent fcntl() api.
*
* - `FIONBIO` sets the `O_NONBLOCK` state (arg is `int *enabled`)
* which is supported on Windows for sockets.
*
* - `FIONCLEX` clears the `O_CLOEXEC` state (no arg) noting that
* this polyfill may be removed in the future, and code should
* migrate to the equivalent fcntl() api.
*
* - `SIOCGIFCONF` takes an struct ifconf object of a given size,
* whose arg is `struct ifconf *`. It implements the Linux style
* and modifies the following:
* - ifc_len: set it to the number of valid ifreq structures
* representingthe interfaces
* - ifc_ifcu.ifcu_req: sets the name of the interface for each
* interface
* The ifc_len is an input/output parameter: set it to the total
* size of the ifcu_buf (ifcu_req) buffer on input.
*
* - `SIOCGIFNETMASK` populates a `struct ifconf *` record with the
* network interface mask. This data structure should be obtained
* by calling `SIOCGIFCONF`.
*
* - `SIOCGIFBRDADDR` populates a `struct ifconf *` record with the
* network broadcast addr. This data structure should be obtained
* by calling `SIOCGIFCONF`.
*
* - `TCGETS` isn't polyfilled; use tcgetattr()
* - `TCSETS` isn't polyfilled; use tcsetattr()
* - `TCSETSW` isn't polyfilled; use tcsetattr()
* - `TCSETSF` isn't polyfilled; use tcsetattr()
