Before calling "attach" a screen object is just a dummy container for
(row, col) values whose purpose is to be sent as part of the "attach"
function call anyway.
Just create the screen in an attached state directly. Keep the complete
(row, col, options) config together. It is still completely valid to
later detach and re-attach as needed, including to another session.
Problem: Wrong display when typing in diff mode with 'smoothscroll'.
Solution: Use adjust_plines_for_skipcol() (zeertzjq).

Problem: Window is updated with potentially invalid skipcol in recursive
window update path. I.e. cursor outside of visible range in
large line that does not fit.
Solution: Make sure it is valid (Luuk van Baal).

Problem: Unable to leave long line with 'smoothscroll' and 'scrolloff'.
Corrupted screen near the end of a long line with 'scrolloff'.
(Ernie Rael, after 9.1.0280)
Solution: Only correct cursor in case scroll_cursor_bot() was not itself
called to make the cursor visible. Avoid adjusting for
'scrolloff' beyond the text line height (Luuk van Baal)

Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.
Closes https://github.com/neovim/neovim/issues/27004.
Problem: Page-wise scrolling with Ctrl-F/Ctrl-B implements
it's own logic to change the topline and cursor.
In doing so, skipcol is not handled properly for
'smoothscroll', and virtual lines.
Solution: Re-use the logic from Ctrl-E/Ctrl-Y while staying
backward compatible as much as possible.

This is the first installment of a multi-PR series significantly
refactoring how highlights are being specified.
The end goal is to have a base set of 20 ish most common highlights,
and then specific files only need to add more groups to that as needed.
As a complicating factor, we also want to migrate to the new default
color scheme eventually. But by sharing a base set, that future PR
will hopefully be a lot smaller since a lot of tests will be migrated
just simply by updating the base set in place.
As a first step, fix the anti-pattern than Screen defaults to ignoring
highlights. Highlights are integral part of the screen state, not
something "extra" which we only test "sometimes". For now, we still
allow opt-out via the intentionally ugly
screen._default_attr_ids = nil
The end goal is to get rid of all of these eventually (which will be
easier as part of the color scheme migration)
This is the command invoked repeatedly to make the changes:
:%s/^\(.*\)|\%(\*\(\d\+\)\)\?$\n\1|\%(\*\(\d\+\)\)\?$/\=submatch(1)..'|*'..(max([str2nr(submatch(2)),1])+max([str2nr(submatch(3)),1]))/g
Problem: Wrong scrolling in Insert mode with 'smoothscroll' at the
bottom of the window.
Solution: Don't use set_topline() when 'smoothscroll' is set.

Problem: [security]: FPE in adjust_plines_for_skipcol
Solution: don't divide by zero, return zero
Prevent a floating point exception when calculating w_skipcol (which can
happen with a small window when the number option is set and cpo+=n).
