termios: merge the termios baud definitions

Browse Source 
Now all platforms unconditionally use the "sane" definitions of the
termios baud constants. Unify them into a common file.

Note: I have made them explicitly unsigned to avoid problems with
compiler warnings for comparisons of unequal signedness or
similar. These constants were historically octal on most platforms,
and so unsigned by default.
