1.3.2

• Allocate memory for MMDB_entry_data_list_s structs in separate chunks
  rather than one large chunk. This simplifies accessing memory in
  MMDB_get_entry_data_list() and increases performance. It builds on the
  changes in 1.3.0 and 1.3.1.
• We no longer export data_pool_* symbols. These are internal functions
  but we were previously exporting them. Pull request by Faidon Liambotis.
  GitHub #162.
• Build with POSIX.1-2008 by default if the system supports it. This allows
  use of open() with O_CLOEXEC. We retain support for systems that
  provide only POSIX.1-2001.
• Open the database with the O_CLOEXEC flag if the system provides it.
  This avoids cases where we could leak fds when called in multi-threaded
  programs that fork() and exec(). Original report and PR by Brandon L
  Black.
• Added a test to ensure we export only intended symbols (e.g. MMDB_*).
