fbb030d7f7 Set the current window pointer to NULL when killing a winlink that is to be
replaced with link-window -k. This prevents it being pushed onto the last
window stack and causing a use-after-free.

Only took me an hour to find this :-/...

9dd72b9583 Add "grouped sessions" which have independent name, options, current window and
so on but where the linked windows are synchronized (ie creating, killing
windows and so on are mirrored between the sessions). A grouped session may be
created by passing -t to new-session.

Had this around for a while, tested by a couple of people.

its callers.

8fa1858a2c New lock-client and lock-session commands to lock an individual client or all
clients attached to a session respectively.

b01dcd7971 Remove the internal tmux locking and instead detach each client and run the
command specified by a new option "lock-command" (by default "lock -np") in
each client.

This means each terminal has to be unlocked individually but simplifies the
code and allows the system password to be used to unlock.

Note that the set-password command is gone, so it will need to be removed from
configuration files, and the -U command line flag has been removed.

This is the third protocol version change so again it is best to stop the tmux
server before upgrading.

9b5f5ed8e8 Move some common and untidy code for window link/unlink into generic functions
instead of duplicating it in move/link window..

ffab22bb35 Only redraw all clients once when the backoff timer expires rather than every
second all the time.

c5ac2579ba When incorrect passwords are entered, behave similarly to login(1) and backoff
for a bit. Based on a diff from martynas@.

f8aa5821be Use "Password:" with no space for password prompts and don't display a *s for
the password, like pretty much everything else. From martynas@ with minor
tweaks by me.

04319964b9 Add a new display-panes command, with two options (display-panes-colour and
display-panes-time), which displays a visual indication of the number of each
pane.

f0635717b3 Switch tmux to use imsg. This is the last major change to make the
client-server protocol more resilient and make the protocol versioning work
properly. In future, the only things requiring a protocol version bump will be
changes in the message structs, and (when both client and server have this
change) mixing different versions should nicely report an error message.

As a side effect this also makes the code tidier, fixes a problem with the way
errors reported during server startup were handled, and supports fd passing
(which will be used in future).

Looked over by eric@, thanks.

Please note that mixing a client with this change with an older server or vice
versa may cause tmux to crash or hang - tmux should be completely exited before
upgrading.

6491274f60 Infrastructure and commands to manage the environment for processes started
within tmux.

There is a global environment, copied from the external environment when the
server is started and each sesssion has an (initially empty) session
environment which overrides it.

New commands set-environment and show-environment manipulate or display the
environments.

A new session option, update-environment, is a space-separated list of
variables which are updated from the external environment into the session
environment every time a new session is created - the default is DISPLAY.

e89e70e715 If there is an error in the configuration file, don't just exit(1) as this can
cause the client to hang. Instead, send the error message, then mark the client
as bad and start a normal shutdown so the server exits once the error is
written.

This also allows some code duplicating daemon(3) to be trimmed and logging to
begin earlier.

Prompted by Theo noticing the behaviour on error wasn't documented.

c1d6d7ac6b Rename struct hdrtype to msgtype which is a better name and can be used even
when struct hdr disappears.

34a82e7629 Make all messages sent between the client and server fixed size.
This is the first of two changes to make the protocol more resilient and less
sensitive to other changes in the code, particularly with commands. The client
now packs argv into a buffer and sends it to the server for parsing, rather
than doing it itself and sending the parsed command data.

As a side-effect this also removes a lot of now-unused command marshalling
code.

Mixing a server without this change and a client with or vice versa will cause
tmux to hang or crash, please ensure that tmux is entirely killed before
upgrading.

0ca6f667e3 Make it so using kill-pane to destroy the last pane in a window destroys the
window instead of being an error.

65deba3a35 Memory could be leaked if a second prompt or message appeared while another was
still present, so add a separate prompt free callback and make the _clear
function responsible for calling it if necessary (rather than the individual
prompt callbacks). Also make both messages and prompts clear any existing when
a new is set.

In addition, the screen could be modified while the prompt is there, restore
the redraw-entire-screen behaviour on prompt clear; add a comment as a
reminder.

daa1faa905 Add a default-terminal option to set the starting value of $TERM in new
windows.

This is "screen" by default and must be either that or something closely
related. This does makes it easier to customise it if necessary.

4c5c125173 When unlocking the server, don't try to clear the prompt on clients without a
prompt (such as the one issuing the unlock request).

This caused the server to die if the wrong password was entered when unlocking
from the command line with -U (nasty).
