commands and allow a command to block execution of subsequent commands. This
allows run-shell and if-shell to be synchronous which has been much requested.
Each client has a default command queue and commands are consumed one at a time
from it. A command may suspend execution from the queue by returning
CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example
run-shell does this from the callback that is fired after the job is freed.
When the command queue becomes empty, command clients are automatically exited
(unless attaching). A callback is also fired - this is used for nested commands
in, for example, if-shell which can block execution of the client's cmdq until
a new cmdq becomes empty.
Also merge all the old error/info/print functions together and lose the old
curclient/cmdclient distinction - a cmdq is bound to one client (or none if in
the configuration file), this is a command client if c->session is NULL
otherwise an attached client.
- rename client and session to start_client and start_session in
window_choose_data struct. also add TREE_OTHER define and reorder the
struct
- rename window_choose_ctx to window_choose_data_run
- don't pass a cmd_ctx into window_choose_create (will let it use a
different client later). instead take type, session, client
- add window_choose_data_free and use it to dispose of wcd rather than
each cmd-*.c doing it individually
- change so ref counting is done by wcd_add and wcd_free rather than
callers. this means 1 ref for each item but what of it :-)
- also add a ref to tree_session - not sure if this is needed?
- all the callbacks except choose-client and find-window are the same so
remove them and add window_choose_default_callback
- reorder/rename some other bits and pieces for tidyness

Allow session tree (C-b s) to expand and collapse sessions with left/right/space keys. From Thomas Adam.
Remove some out of date text from man page, from Thomas Adam.
Instead of requiring a prompt to enter all numbers >10, go back to
0-9a-z and add A-Z and enter the prompt when M-0 to M-9 are pressed
(like in copy mode). Prompted by request from mcbride@, help from Thomas
Adam.
Instead of numbering choose mode items 0-9a-z and then nothing, number
them all and if there are more than 10 use a prompt when 0-9 is
pressed. From Thomas Adam.
Provide common helper function for adding windows and sessions to choose
lists and expand %% in command before using it rather than at callback
time. From Thomas Adam.
function. We were only ever using the client to find the session anyway.
This allows send-key to work properly for manipulating copy mode from
outside tmux.
