[raccess] Skip unrequired resource access rules by Darwin VFS.
When a resource fork access rule by Darwin VFS could open the
resource fork but no font is found in it, the rest of rules
by Darwin VFS are skipped. It reduces the warnings of the
deprecated resource fork access method by recent Darwin kernel.
Fix MacPorts ticket #18859:
http://trac.macports.org/ticket/18859
* src/base/ftobjs.c (load_face_in_embedded_rfork):
When FT_Stream_New() returns FT_Err_Cannot_Open_Stream, it
means that the file is possible to be fopen()-ed but zero-sized.
Also there is a case that the resource fork is not zero-sized,
but no supported font exists in it. If a rule by Darwin VFS
falls into such cases, there is no need to try other Darwin VFS
rules anymore. Such cases are marked by vfs_rfork_has_no_font.
If it is TRUE, the Darwin VFS rules are skipped.
