Issue 4876/4: Enable fontname replacing in TrueType functions

Issue 4876/3: Enable fontname replacing in Pango_font class

This commit enables fontname replacing for CFF (OTF/OTC) fonts.

Issue 4876/2: Enable fontname replacing in Open_type_font class

This commit enables fontname replacing for CFF (OTF/OTC) fonts.

Issue 4876/1: Add fontname replacing function for CFF (OTF/OTC) fonts

For CFF (OTF/OTC) fonts,
FT_Get_Postscript_Name ()
in FreeType 2.6+ gets the name in 'name' table.
However, we want the name in 'CFF' table instead of in 'name' table
because output postscript file is embedded only 'CFF' table of the font.

They are inconsistent for some OpenType/CFF Collection fonts (OTC).

This function can get the name in 'CFF' table.

TODO: Check conflicts between fonts which have same name in 'CFF' table
but different name in 'name' table.

If I understand correctly, this caused by FreeType 2.5.5 or earlier.

For example, if you use a non-Japanese (e.g. Chinese or Korean) font in NotoSansCJK.ttc ver. 1.004, FreeType 2.5.5 gets a Japanese postscript name.

Therefore, LilyPond might embed the fonts with wrong postscript name if you use FreeType 2.5.5 or earlier.
Even if the name is wrong, the glyphs are correct.

FreeType 2.6+ is fixed it.

For LilyPond official site's binaries:
Current GUB uses FreeType 2.4.12.
So I'm making the GUB's patch which update FreeType.

For others:
Bump up required or recommended version of FreeType?
