Remove ABI-breaking field in public PS_InfoFontRec definition.
Instead, we define a new internal PS_FontExtraRec structure to
hold the additionnal field, then place it in various internal
positions of the corresponding FT_Face derived objects.

I. IMPORTANT BUG FIXES
+ - Very unfortunately, FreeType 2.3.8 contained a change that
+ broke its official ABI. The end result is that programs compiled
+ against previous versions of the library, but dynamically linked
+ to 2.3.8 can experience memory corruption if they call the
+ FT_Get_PS_Font_Info() function.
+
+ We recommend all users to upgrade to 2.3.9 as soon as possible,
+ or to downgrade to a previous release of the library if this is
+ not an option.
+
+ The origin of the bug is that a new field was added to the
+ publicly defined PS_FontInfoRec structure. Unfortunately objects
+ of this type can be stack or heap allocated by callers of
+ FT_Get_PS_Font_Info(), resulting in a memory buffer over-write
+ with its implementation in 2.3.8.
+
+ If you want to know if your code is vulnerable to this issue,
+ simply search for the substrings "PS_FontInfo" and
+ "PS_Font_Info" in your source code. If none is found, your code
+ is safe and will not be affected.
+
+ The FreeType team apologizes for the problem.

- The POSIX support of MacOS resource-fork fonts (Suitcase fonts
and LaserWriter Type1 PostScript fonts) was broken in 2.3.8. If
FreeType2 is built without Carbon framework, these fonts are not
