Sprinkle about some cycle wasting checks for the win pointer being
null. Unfortunately, ncurses does this and there is some sloppy code
out there that relies on the check resulting in segfaults in
NetBSD curses which then, of course, gets blamed for the error.

Expand __CTRACE() to __nothing #ifndef DEBUG.

Remove most of #ifdef DEBUG around __CTRACE() calls.

No binary changes, except for line numbers for assert().

Rework previous fix for getch cursor position when cursor is moved
without refresh. If the window is not dirty but the window cursor
position does not match curscr then move the cursor. This fixes

Back out incorrect fix for PR 53617 and fix it in a different way.
Keep track of the cursor location, if getch is called without a refresh
and without pending updates (dirty windows) then move the cursor to the
correct location directly. Doing this prevents unnecessary refreshes.

Rename the old __waddbytes function to _cursesi_waddbytes and add a
parameter that controls whether or not certain characters in the
string are interpreted or not (things like tab being expanded).

Make __waddbytes a wrapper for _cursesi_waddbytes that passes all
parameters and sets the flag for character interpretation for backward
compatibility.

Fix an incipient bug in _cursesi_waddbytes where garbage would have
been written to the terminal if the terminal TABSIZE was set > 8 and
character interpretation is on.

Convert all internal __waddbytes calls to use _cursesi_waddbytes, fix
the function prototypes and add a new flag that will be used later.

Fix the addchstr family functions so that they call _cursesi_waddbytes
with character interpretation off as per SUSV2.

Truncate string to RHS of the window - SUSv2 says we should.

Remove clause 3 and 4 from TNF licenses

Add debug "areas" that allow selective debugging by setting the
"CURSES_TRACE_MASK" environment variable. Postive vales include
debug areas, negative values exclude them.

Make i an int to please lint and remove a cast.

Add addchstr() family of functions.
