48e33179d4 server-client, popup, screen-redraw: fix damage-system regressions
Fixes the four bugs caught by the regression tests added in aed1209c
(popup-drag-status-line.sh, popup-drag-wide-character.sh,
popup-drag-pane-prompt.sh, switch-client-redraw.sh), based on fixes
from Michael K. Darling (github.com/darlingm/tmux, pr5516-regression-
fixes), reviewed and adapted:

- server-client.c: server_client_set_session()'s check for whether the
  client's window actually changed compared old->curw to s->curw, but
  when old == s these read the same, already-updated field, so a
  same-session window switch was never detected. Compare against the
  client's own cached redraw scene instead (redraw_client_has_window(),
  new in screen-redraw.c/tmux.h). Taken from darlingm as-is.

- popup.c: popup_damage() only translated a popup's client-coordinate
  rectangle into window coordinates, so a popup dragged across the
  status line never triggered a status-line redraw once it moved away -
  status_redraw()'s own "skip if content unchanged" optimization
  suppressed it, since only the popup moved, not the status content.
  Now detects overlap with the status line and forces a redraw via the
  existing (previously unused) CLIENT_REDRAWSTATUSALWAYS flag, and
  properly clips the reported rectangle to the pane area for
  status-at-top/bottom/off. Taken from darlingm as-is.

- screen-redraw.c: redraw_draw_damage_rect() clipped a span to a damage
  rectangle's raw geometric edges, which have no idea what's in the
  grid, so a clip edge could land mid-character and tear a wide
  character in half. Added redraw_damage_grow_span_clip(): widen the
  clip by one cell on each edge that isn't already at the span's own
  boundary. Reimplemented simpler than darlingm's version (which walked
  grid cells per span type via a switch and direct grid lookups) -
  since no grid cell is ever wider than two columns, an unconditional
  one-cell margin is always enough to pull a split character back in,
  with no need to inspect grid content at all.

- screen-redraw.c: redraw_draw_damage_rect() also never re-overlaid a
  pane's active in-pane prompt after drawing its underlying content, so
  damage crossing a prompt row erased it until an unrelated redraw
  restored it. Factored the existing full-redraw prompt-building code
  into a shared redraw_make_pane_prompt() helper and added
  redraw_damage_draw_pane_prompt(), which recomposes the prompt over
  the drawn range. Taken from darlingm as-is.

All 9 regression tests in regress/ now pass. redraw_damage_grow_span_clip
was verified independently by disabling it and confirming
popup-drag-wide-character.sh reproduces its original failure.

48cdd85886 server-client: consume window damage during the normal redraw pass
redraw_client_damage() (added previously, unused until now) is called
from server_client_check_redraw()'s normal redraw pass, and
server_client_any_pane_redraw() now also checks for pending window
damage so a client with only damage (no PANE_REDRAW/PANE_REDRAWSCROLLBAR
flags) still gets its redraw pass run.

server_client_check_redraw() now returns whether the redraw was deferred
(waiting for outstanding tty output to drain) rather than performed. A
deferred redraw no longer escalates to a full CLIENT_REDRAWWINDOW to
avoid losing what was pending - server_client_loop() now only clears
PANE_REDRAW, PANE_REDRAWSCROLLBAR and window damage once every client
viewing a window actually drew this pass (tracked via a new per-window
redraw_deferred flag), otherwise they're left in place and retried in
their normal, narrowly-scoped form.

server_client_set_session() now redraws only if the client's session or
current window actually changed, not on every call (e.g. switch-client
-t= from clicking a pane name in the status line resolves here even
when nothing besides the active pane changed).

A drag callback's mouse_drag_update() now opens a sync region itself
(tty_sync_start()) before its first write, so a fast-path write it makes
directly and a later correction arriving via redraw_client_damage() end
up in the same atomic terminal update instead of two visible frames.
