Added missing header back to source dist

1.1.1

Release for 1.1.1

Improved error handling, Windows fixes, Autotool fixes

• Previously, when there was an error in MMDB_open(), errno would
  generally be overwritten during cleanup, preventing a useful value from
  being returned to the caller. This was changed so that the errno value
  from the function call that caused the error is restored before returning to
  the caller. In particular, this is important for MMDB_IO_ERROR errors as
  checking errno is often the only way to determine what actually failed.
• If mmap() fails due to running out of memory space, an
  MMDB_OUT_OF_MEMORY_ERROR is now returned from MMDB_open rather than an
  MMDB_IO_ERROR.
• On Windows, the CreateFileMappingA() handle was not properly closed if
  opening the database succeeded. Fixed by Bly Hostetler. GitHub #75 & #76.
• On Windows, we were not checking the return value of CreateFileMappingA()
  properly for errors. Fixed by Bly Hotetler. GitHub #78.
• Several warnings from Clang's scan-build were fixed. GitHub #86.
• All headers are now installed in $(includedir). GitHub #89.
• We no longer install maxminddb-compat-util.h. This header was intended for
  internal use only.

Minor fixes and Windows improvements

• If you used a non-integer string as an array index when doing a lookup with
  MMDB_get_value, MMDB_vget_value, or MMDB_aget_value, the first element
  of the array would be returned rather than an error. A
  MMDB_LOOKUP_PATH_DOES_NOT_MATCH_DATA_ERROR error will now be returned.
  GitHub #61.
• If a number larger than LONG_MAX was used in the same functions,
  LONG_MAX would have been used in the lookup. Now a
  MMDB_INVALID_LOOKUP_PATH_ERROR error will be returned.
• Visual Studio build files were added for unit tests and some compatibility
  issues with the tests were fixed.
• Visual Studio project was updated to use property pages. Patch by Andre.
  GitHub #69.
• A test failure in t/compile_c++_t.pl on new installs was fixed.

Windows and C++ improvements

1.0.3 - 2014-12-02

• A memory and file handle leak on Win32 was fixed when getting the database
  size fails. Patch by Federico G. Schwindt. GitHub PR #49.
• Documentation fix. Federico G. Schwindt. GitHub PR #50.
• Added Visual Studio build files and fixed incorrect CreateFileMappingA
  usage. Patch by Andre. GitHub #52.
• The includes for the Windows header files were made lowercase in order to
  match the actual file names on case-sensitive file systems. GitHub PR #57.
• Removed realloc() calls that caused warnings on Windows and generally
  cleaned up memory allocation in MMDB_vget_value(). See relevant discussion
  in GitHub #52.
• Added an extern "C" { ... } wrapper to maxminddb.h when compiling with a
  C++ compiler. GitHub #55.

Bug fixes

• Fixed a number of small issues found by Coverity.
• When freeing the MMDB struct in MMDB_close() we make sure to set the
  pointers to NULL after freeing the memory they point to. This makes it safe
  to call MMDB_close more than once on the same MMDB_s struct
  pointer. Before this change, calling this function twice on the same pointer
  could cause the code to free memory that belonged to something else in the
  process. Patch by Shuxin Yang. GitHub PR #41.

Added missing LICENSE and NOTICE files to distribution.

No code changes.

First production release

• Bumped version to 1.0.0. No code changes.

Memory leak and FreeBSD fixes

• There was a leak in the MMDB_open() sub when it was called against a file
  which did not contain any MMDB metadata. Reported by Federico
  G. Schwindt. GitHub issue #36.
• Fixed an error that occurred when passing AI_V4MAPPED to getaddrinfo() on
  FreeBSD. Apparently this macro is defined but doesn't work the way we
  expected it to on that platform.
• Made sure to call freeaddrinfo() when a call to getaddrinfo() fails but
  still allocated memory.
• Fixed a segfault in the tests that occurred on FreeBSD if we passed a NULL
  value to freeaddrinfo().
• Added a missing step to the README.md file for installing from our GitHub
  repository. Patch by Yasith Fernando.
• Added instructions for installing via Homebrew. Patch by Yasith Fernando.

Add missing file to tarball

• The previous tarball failed to compile because it was missing the
  src/maxminddb-compat-util.h file. Reported by Günter Grodotzki. GitHub issue
  #18.

MinGW support, consting, and license change

• Added support for compiling in the MinGW environment. Patch by Michael Eisendle.
• Added const declarations to many spots in the public API. None of these should require changes to existing code.
• Various documentation improvements.
• Changed the license to the Apache 2.0 license.
