window_pane_redraw_floating() reports damage for only a floating pane's
old and new rectangle (via redraw_damage_window(), grown by one cell to
cover its border frame - see the "floating" case in screen-redraw.c),
instead of the caller falling back to a full window redraw. Any other
pane whose *scrollbar strip* - not its whole body - intersects either
rectangle still gets PANE_REDRAWSCROLLBAR directly, since scrollbars
aren't covered by the damage system.
Introduce a per-window list of damaged rectangles (struct redraw_damage)
and redraw_damage_window() to record them, redraw_client_damage() to
consume them by composing exactly the damaged cells (via a new
redraw_draw_damage_rect(), which also force-refreshes any pane-status
span it touches, since window_make_pane_status()'s content-diff check
has no way to know the physical cells were disturbed by something else).
redraw_draw_span() now takes an explicit [clip_x, clip_x + clip_n) range
instead of always drawing a span's full width, so a damage rectangle can
redraw just the portion of a span it actually covers.
screen_write_redraw_cb() - the fallback when a write can't be applied
directly to the terminal - now reports damage for just the affected row
via this mechanism, instead of unconditionally flagging the whole pane
for a full redraw.
wp->flags |= PANE_REDRAWSCROLLBAR was set unconditionally whenever a pane
reserved a scrollbar, even if layout_fix_panes() left its geometry
completely unchanged - forcing a needless scrollbar redraw on every layout
pass. Move it inside the existing "did this pane's geometry actually
change" check.

Always unzoom before splitting window, for floating panes also. We already unzoomed for tiled panes and this does the same for floating panes (until we support having them float over a zoomed pane). From Éric NICOLAS.
Forks are just wasting CI cycles spinning actions which are probably not
looked at. Also avoid locking issues and PRs on any forks with
upstream's policies.

Do not attempt to drain write buffer on stuck clients, since it requires a weird dance to make libevent do it. Instead, just ignore the client and destroy the buffer normally if not drained in 10 seconds.
