d34c5681a4 curses: fix ripoffline 
When creating stdscr, ensure it's placed and sized in accordance with
lines ripped off.
LINES is no longer adjusted for lines ripped off.
POSIX makes no mention that it should be adjusted.
Bottom lines are now placed correctly.
Lines ripped off are now displayed after calling initscr.

Fixes PR #53635

5128a2ed79 POSIX says that use_env(3) must precede setupterm(3). 
The former lives in curses.h, but the latter lives in term.h.

This is solved by moving the function to libterminfo.
Because the environment can affect the terminal capabilities for
lines and columns, it follows that the tty size should affect it to.
So move that code to libterminfo and adjust in libcurses.

8dcd50a6a0 Move ESCDELAY to curses.c so all globals are close to each other.

reentrant.

64b2ce979c If either set_escdelay(3) or set_tabsize(3) are called, set _reentrant 
to ensure we use the saved value for the sceen.

This effectively makes ESCDELAY and TABSIZE read-only when either
of these functions are called.

when the terminal is resized.

8ed5bc1d62 Fix a NULL dereference if the exit_alt_charset_mode capability is not defined. 
The previous version of this file changed a terminal initialisation test on
the exit_attribute_mode capability, checking for the exit_alt_charset_mode
capability as a substring, rather than performing a search for the hard-coded
^O character.

That works better on terminals where ^O is not the correct value for
exit_alt_charset_mode.  But it works worse on terminals that don't have a
definition specified for exit_alt_charset_mode.

For example:

% TERMCAP='xterm:me=\E[m:' TERM=xterm vi
segmentation fault (core dumped)  TERMCAP='xterm:me=\E[m:' TERM=xterm vi

The crash can be avoided (without fixing the bug) by defining
exit_alt_charset_mode:

% TERMCAP='xterm|:me=\E[m:ae=:' TERM=xterm vi
ex/vi: Error: xterm: No such process

We now test exit_alt_charset_mode for NULL before continuing with the fatal
test, restoring the original no-crash behaviour.

XXX does_ctrl_o() is now just a naive reimplementation of strstr(), so should
probably just use strstr() instead.

43d5eb454b Prepare curses for the possibility of changing from termcap to terminfo. 
term.h #defines lines, pad_char and no_color_video macros which conflict
with existing curses code. We change lines to alines and nlines depending
on use, pad_char to padchar and no_color_video becomes no_color_attributes
but with a strong alias from no_color_video.
