stdio: split byte- and wide-char-oriented low-level output functions
Introduce function __swbufw_r and macros/inline-functions called
__swputc_r. Call these functions/macros exclusively from wide-char
functions.
This allows to set and test the stream orientation correctly even if
output is only performed using byte-oriented macros from stdio.h.
