Having split out the user and kernel structures it turns out that some
non glibc C libraries pull their termios struct from the kernel headers
directly or indirectly. This means we must keep "struct termios" as the
library sees it correct for the old ioctls. Not a big problem just
shuffle the names and ifdef around a bit
