add a link of winlinks to each window and a pointer to the session to
each winlink. Also rewrite the alerts processing to return to the old
behaviour (alert in any window sets the flag on any winlink).
but there is also now a global command queue. Instead of command queues
being dispatched on demand from wherever the command happens to be
added, they are now all dispatched from the top level server
loop. Command queues may now also include callbacks as well as commands,
and items may be inserted after the current command as well as at the end.
This all makes command queues significantly more predictable and easier
to use, and avoids the complex multiple nested command queues used by
source-file, if-shell and friends.
A mass rename of struct cmdq to a better name (cmdq_item probably) is
coming.
which could potentially free the currently running command, so we need
to take a reference to it in cmdq_continue_one.

confusing, particularly trying to automatically figure out what target
hooks should be using. So simplify it:
- drop before hooks entirely, they don't seem to be very useful;
- commands with special requirements now fire their own after hook (for
example, if they change session or window, or if they have -t and -s
and need to choose which one the hook uses as current target);
- commands with no special requirements can have the CMD_AFTERHOOK flag
added and they will use the -t state.
At the moment new-session, new-window, split-window fire their own hook,
and display-message uses the flag. The remaining commands still need to
be looked at.
sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank
cells using the current background colour rather than the default
colour.
On modern systems BCE doesn't really have many benefits, but most other
terminals now support it, some (lazy) applications rely on it, and it is
not hard to include now that we have pane background colours anyway.

- Prepare the state again before the "after" hooks are run, because the
command may have killed or moved windows.
- Use the hooks list from the newly prepared target, not the old hooks
list (only matters for new-session really).
- Correctly detect an invalid current state and ignore it in
cmd_find_target ("killw; swapw").
- Change neww, new, killp, killw, splitw, swapp, swapw to update the
current state (used if no explicit target is given) to something more
useful after they have finished. For example, neww changes it to the
newly created window.
Hooks are still relatively new and primitive so there are likely to be
more changes to come.

support line editing and instead executes a command as soon as a
non-number key is pressed. Add a -N flag to command-prompt for the same
in copy mode. Reported by Theo Buehler.
The vi-copy and emacs-copy mode key tables are gone, and instead copy
mode commands are bound in one of two normal key tables ("copy-mode" or
"copy-mode-vi"). Keys are bound to "send-keys -X copy-mode-command". So:
bind -temacs-copy C-Up scroll-up
bind -temacs-copy -R5 WheelUpPane scroll-up
Becomes:
bind -Tcopy-mode C-Up send -X scroll-up
bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up
This allows the full command parser and command set to be used - for
example, we can use the normal command prompt for searching, jumping,
and so on instead of a custom one:
bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"
command-prompt also gets a -1 option to only require on key press, which
is needed for jumping.
The plan is to get rid of mode keys entirely, so more to come eventually.
