1.2.1

• Use autoconf to check the system's endianness rather than trying to do this
  with compiler-defined macros like __BYTE_ORDER__. Apparently this didn't
  work properly on a Sparc system. GitHub #120.
• Several compiler warnings on Visual C++ were fixed. Pull request by Marcel
  Raad. GitHub #130.
• Fix segmentation faults found in MMDB_open() using afl-fuzz. This
  occurred on corrupt databases that had a data pointer large enough to
  cause an integer overflow when doing bound checking. Reported by Ryan
  Whitworth. GitHub #140.
• Add --disable-tests option to configure. Pull request by Fabrice
  Fontaine. GitHub #136.
