[Devel] Some fixes and bug reports.

[山内 英敏]

Hello,

Here are few fixes on freetype2

* fix FT_Get_Sfnt_Name_Count works correctly.
* fix to compile with #undef TT_CONFIG_OPTION_BYTECODE_INTERPRETER.

And I found a bug on truetype driver.

When FT_LOAD_NO_SCALE is true in load_flags (e.g. when we using
autohiner), *ALL* embedded bitmaps are ignored.  I found the reason in
Load_Glyph on freetype2/src/truetype/ttdriver.c:313,
-----
    if ( load_flags & FT_LOAD_NO_SCALE )
      size = NULL;
-----
in this case, we cannot find appropriate size of embedded bitmaps.
We should fix this bug but I do not know any good solutions yet.
And I am busy now.....
