Subject: [PATCH] Add byte order swapping macros to configure

Changes:

    * Make ./configure generate src/config.h, which will contain the
      appropriate #include for endian.h, or #defines to provide
      alternatives

    * Make sure to include config.h in src/frame.c to allow compiling
      on macOS
