      Fix various build issues and warnings.
    Building and testing:
      Update configure-time universal build checks for macOS.
      Update config.guess and config.sub.
      If we look for an SSL library with pkg-config in configure script,
        try pkg-config first.
      If we have pkg-config and Homebrew, try to set pkg-config up to
        find Homebrew packages.

      Support reading version 1.2, which some writers produce, and which
          is the same as 1.0 (some new block types were added, but
          that's not sufficient reason to bump the minor version number,
          as code that understands those new block types can handle them
          in a 1.0 file)
      Drop support for text-mode USB captures, as we require a 2.6.27
          or later kernel (credit to Chaoyuan Peng for noting the
          sscanf vulnerabilities in the text-mode code that got me to
          realize that we didn't need this code any more)
      Bluetooth: fix non-blocking mode.
      Don't assume that all compilers used to build for Linux support
          the __atomic builtins
      Add more information in "interface disappeared" error messages, in
        the hopes of trying to figure out the cause.
      Treat ERROR_DEVICE_REMOVED as "device was removed".
      Indicate in the error message which "device was removed" error
      Report the Windows error status if PacketSendPacket() fails.
      Use %lu for ULONGs in error message formats.
      Don't treat the inability to find airpcap.dll as an error.
      Ignore spurious error reports by Microsoft Surface mobile
          telephony modem driver
