Minor doc improvement.

Suggested by Ulrich Eckhardt <ulrich.eckhardt@dominolaser.com>.
* src/smooth/ftgrays.c One final pragma to silence 64-bit MSVC.
Fix Savannah bug #39266.

If memory allocations fail at certain points while opening a font,
FreeType can either crash due to a NULL dereference or leak memory.

* include/freetype/internal/ftobjs.c (FT_Face_InternalRec,
FT_LibraryRec): Make `refcount' a signed integer.  If, for example,
FT_Open_Face() fails in a memory allocation before the face's
reference count is set to 1, a subsequent `FT_Done_Library' call
would otherwise loop over `FT_Done_Face' 2^32 times before freeing
the face.

* src/base/ftobjs.c (open_face): Initialize `stream' and friends
earlier.
(FT_Open_Face) <Fail>: Behave correctly if `node' is NULL.
(FT_Destroy_Module) <Fail>: Check that `renderer_clazz' is valid.
Fix Savannah bug #39269.

* src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Free memory in
case of reacollocation failures.
Update CHANGES; tag some auto-hinter properties as still experimental.
* Version 2.5.0 released.
=========================
