* lib/stdio: All output stream logic was modified to support CONFIG_STDIO_LINEBUFFER.
If standard C buffered I/O is enabled (CONFIG_STDIO_BUFFER_SIZE > 0), then this
option may be added to force automatic, line-oriented flushing the output buffer
for printf() fprintf(), and vfprintf(). When a newline is encountered in the
format string, the output buffer will be flushed. This (slightly) increases
the NuttX footprint but supports the kind of behavior that people expect for
printf.
