This fixes a regression in commmit 70ac43ce77,
where the original screen size would be used to scroll after the terminal had
been resized. If the screen was shrunk, this caused display problems when
running under GNU Screen.
Using output_screen size means that it stands a better chance of working on
non-default screens, too.
These globals were used to store the original terminal dimesions from the terminal database (or
in the case of reattaching, supplied by scr-bx) to be applied if the current terminal dimensions
could not be determined.
Instead, we leave the original terminal dimensions in current_term->TI_lines and current_term->TI_cols,
and create current_term->li and current_term->co to store the current terminal dimensions (as eg.
supplied by scr-bx).
This table isn't modified or referenced outside of term.c, so it can be const static.
The 'const' moves ~20K from the data segment to the text segment (on 64 bit), reducing the total size of
the BitchX data segment by 10%.
ncurses can optionally declare tigetstr(), tigetnum() and tigetflags() with a
const char * argument, indicated by the NCURSES_CONST macro. So we use this
macro, if available, to optionally declare cap2str.iname as const char *.

This ensures portability to systems with a fixed-argument list declaration
of tparm(), like NetBSD curses.

This simplifies the inclusion logic in ircterm.h, and updates term.c to include
term.h if available. This removes the declarations for setupterm(), tigetstr(),
tigetnum(), tigetflag(), tgetent(), tgetstr(), tgetnum() and tgetflag() from
term.c as those should be defined in term.h or termcap.h.
This should make the system declaration of tparm() available to term.c, which
will fix a crash on NetBSD x86-64 caused by the implicit declaration of tparm()
having a return type of 'int' while the real function has a return type of
'char *'.
We have to include term.h in term.c, not in ircterm.h because term.h defines
a large number of macros, at least two of which ('lines' and 'goto_window')
conflict with names in use in the rest of the codebase.

The pointer passed to tgetstr() must not be reset each time around the loop.
Also some other minor cleanups in term_init().
