gettytab's dx flag is supposed to set decctlq, which is the opposite of
ixany, but was setting ixany instead.

Fix this by reversing the logic.

Bug report and fix from Piotr Durlej, thanks!

silence a compiler warning
OK millert

unifdef XXX_DELAY which is older than i am

More "(<blah> *)0" -> NULL, avoiding any stdarg functions.

Feedback millert@ kettenis@

assign pointers to NULL rather than 0

remove excess tab at end of line (how did they afford the extra bytes in
the dark ages?)

remove ancient support for edited hostnames. ok deraadt (long ago)

remove the prototype for compatflags() which was removed in 2013.

Drop the f0, f1, f2 gettytab capabilities that were used to poke
magic numbers into sgttyb. The "modern" replacement for f# is the
set of i#, o#, c#, l# to poke magic numbers into termios.
ok miod@

use poll + nanosleep instead of select with a fixed size fd_set

Add traditional handling of all upper-case input

Implement more tty flags for better portability from other systems:

XCASE - canonical input/output processing
IUCLC - translate uppercase to lowercase on input
OLCUC - translate lowercase to uppe

Implement more tty flags for better portability from other systems:

XCASE - canonical input/output processing
IUCLC - translate uppercase to lowercase on input
OLCUC - translate lowercase to uppercase on output
OCRNL - translate carriage return to newline on output
ONOCR - do not output carriage return at column 0
ONLRET - newline performs carriage return function

In addition the tty compatibility interface supports LCASE properly.

Look at termios(4) for a more complete description of the above flags.
