Remove empty Fd. Use minus for return value. End list. Sort SEE ALSO.

Implement tcgetwinsize() and tcsetwinsize() in libc, with access
via <termios.h> (and document them.) Bump libc minor number for them.

Arrange for "struct winsize" to become visible in <termios.h>

Fix stty(1) so that "cols" is reported as the arg to set number of columns,
and "columns" is the alias, rather than the other way around, as "cols" is
what has been added to POSIX.

This is to conform with updates to be included in 1003.1 issue 8
