Fix to use MacOS legacy font support by Masatake Yamato,
on Mac OS X. It is not working since 2.3.5. In FT_Open_New(),
if FT_New_Stream() cannot mmap() specified file and cannot
seek to head of specified file, it returns NULL stream
and FT_Open_New() returns the error immediately. On MacOS,
most legacy MacOS font falls into such scenario because
their data forks are zero-sized and cannot seek. To proceed
to guessing of resource fork fonts, the functions for legacy
MacOS font must lay by NULL stream returned by FT_New_Stream().
Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
cannot mmap() the specified file and cannot seek to head of the
specified file, it returns NULL stream and FT_Open_New() returns the
error immediately. On MacOS, most legacy MacOS fonts fall into such
a scenario because their data forks are zero-sized and cannot be
sought. To proceed to guessing of resource fork fonts, the
functions for legacy MacOS font must properly handle the NULL stream
returned by FT_New_Stream().
* src/base/ftobjs.c (IsMacBinary): Returns an error
FT_Err_Invalid_Stream_Operation immediately when NULL stream
is passed.
* src/base/ftobjs.c (IsMacBinary): Return error
FT_Err_Invalid_Stream_Operation immediately when NULL stream is
passed.
(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
to fallback. Originally, legacy MacOS font is tested in the cases
of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
.dfont header is combined). Now the case of
FT_Err_Cannot_Open_Stream is included.

* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream
is NULL, skipping FT_Stream_Seek() to the head of stream
and proceed to unit testing of raccess_guess_XXX().
FT_Stream_Seek() for NULL stream causes Bus error on Mac OS X.
(raccess_guess_apple_double): Returns FT_Err_Cannot_Open_Stream
* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
skip FT_Stream_Seek(), which seeks to the head of stream, and
proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
for a NULL stream causes a Bus error on Mac OS X.
(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
immediately if passed stream is NULL.
(raccess_guess_apple_single): Ditto.
