FT_Get_X11_Font_Format to return an X11-compatible string describing the
font format of a given face. This was put in a new optional base source
file, corresponding to a new public header (named FT_XFREE86_H since
this function should only be used within the XFree86 font server IMO).
* include/freetype/config/ftheader.h: adding FT_XFREE86_H, though it's
not documented yet.
* include/freetype/t1tables.h, src/base/fttype1.c: adding two new APIs
named "FT_Get_PS_Font_Info" and "FT_Has_PS_Glyph_Names". This required
a new optional source in 'src/base' named "fttype1.c"
* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: updating
build control files for the new files "ftxf86.c" and "fttype1.c" in
src/base
