Use BOTHER to set the baudrate

[yegorich]

Use the modern way to set the baudrate using an integer and not a macro.

struct termios2 tio;

ioctl(fd, TCGETS2, &tio);
tio.c_cflag &= ~CBAUD;
tio.c_cflag |= BOTHER;
tio.c_ispeed = 12345;
tio.c_ospeed = 12345;
ioctl(fd, TCSETS2, &tio);

I like the idea of adding this code.

Is there any risk this new API won't work on some older systems? If so, should we offer both, default to the new, and perhaps have a command line option to force the old method if needed?

That's a good question. Adding support can be a little bit tricky. See this note.
