[PATCH] tty: preparatory structures for termios revamp

In order to sort out our struct termios and add proper speed control we need
to separate the kernel and user termios structures.  Glibc is fine but the
other libraries rely on the kernel exported struct termios and we need to
extend this without breaking the ABI/API

To do so we add a struct ktermios which is the kernel view of a termios
structure and overlaps the struct termios with extra fields on the end for
now.  (That limitation will go away in later patches).  Some platforms (eg
alpha) planned ahead and thus use the same struct for both, others did not.

This just adds the structures but does not use them, it seems a sensible
splitting point for bisect if there are compile failures (not that I expect
them)
