*int _output(stream, format, argptr), static int output(format, argptr)
*
*Purpose:
* Output performs printf style output onto a stream. It is called by
* printf/fprintf/sprintf/vprintf/vfprintf/vsprintf to so the dirty
* work. In multi-thread situations, _output assumes that the given
* stream is already locked.
*
* Algorithm:
* The format string is parsed by using a finite state automaton
* based on the current state and the current character read from
* the format string. Thus, looping is on a per-character basis,
* not a per conversion specifier basis. Once the format specififying
* character is read, output is performed.
*
*Entry:
* FILE *stream - stream for output
* char *format - printf style format string
* va_list argptr - pointer to list of subsidiary arguments
*
*Exit:
* Returns the number of characters written, or -1 if an output error
* occurs.
*ifdef _UNICODE
* The wide-character flavour returns the number of wide-characters written.
*endif
*
*Exceptions:
