Function qemu_dirent_dup() is currently only used by 9pfs server, so move
it from project global header osdep.h to 9pfs specific header 9p-util.h.

If you don't mind I send a separate, subsequent patch that just wipes the "@c"s away, and leave this patch as-is (as this one is pure refactoring). Alternatively I could replace the "@c"s by kerneldoc's solution which apparently is "::foo" I think ("foo" being the inlined C code). Best regards, Christian Schoenebeck

Yes, I agree that should be a separate patch, and just removing the formatting is the simplest approach. thanks -- PMM
