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. Signed-off-by: H.
