simplify vdprintf implementation greatly based on recent vfprintf changes
since vfprintf will provide a temporary buffer in the case where the target FILE has a zero buffer size, don't bother setting up a real buffer for vdprintf. this also allows us to skip the call to fflush since we know everything will be written out before vfprintf returns.
