ff599f4004 Remove the cmd_find_{session,window,pane,index} functions (which are
just wrappers around cmd_find_target) and just use cmd_find_target
directly.

4a4daf1303 Instead of every command resolving the target (-t or -s) itself, prepare
the state (client, session, winlink, pane) for it it before entering the
command. Each command provides some flags that tell the prepare step
what it is expecting.

This is a requirement for having hooks on commands (for example, if you
hook "select-window -t1:2", the hook command should to operate on window
1:2 not whatever it thinks is the current window), and should allow some
other target improvements.

The old cmd_find_* functions remain for the moment but that layer will
be dropped later.

Joint work with Thomas Adam.

95195f5258 Rewrite of the target resolution internals to be simpler and more
consistent but with much less duplication, but keeping the same internal
API. Also adds more readable aliases for some of the special tokens used
in targets (eg "{start}" instead of "^"). Some behaviours may have
changed, for example prefix matches now happen before fnmatch.

bf635e7741 Rewrite of tmux mouse support which was a mess. Instead of having
options for "mouse-this" and "mouse-that", mouse events may be bound as
keys and there is one option "mouse" that turns on mouse support
entirely (set -g mouse on).

See the new MOUSE SUPPORT section of the man page for description of the
key names and new flags (-t= to specify the pane or window under mouse
as a target, and send-keys -M to pass through a mouse event).

The default builtin bindings for the mouse are:

    bind -n   MouseDown1Pane select-pane -t=; send-keys -M
    bind -n MouseDown1Status select-window -t=
    bind -n   MouseDrag1Pane copy-mode -M
    bind -n MouseDrag1Border resize-pane -M

To get the effect of turning mode-mouse off, do:

    unbind -n MouseDrag1Pane
    unbind -temacs-copy MouseDrag1Pane

The old mouse options are now gone, set-option -q may be used to
suppress warnings if mixing configuration files.

410a3abbef Add a wait-for command which blocks a client on a named channel until it

20636d956d Add a command queue to standardize and simplify commands that call other
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.

f308ba93aa Change the way the working directory for new processes is discovered. If
default-path isn't empty, it is used. Otherwise:

1) If tmux neww is run from the command line, the working directory of the
   client is used.

2) Otherwise sysctl KERN_PROC_CWD is used to retrieve the current
   working directory of the process in the active pane.

3) If that fails, the directory where the session was created is used.

Support code by Romain Francois, OpenBSD specific bits by me.

Note this requires a recent userland and kernel with KERN_PROC_CWD.

7502cb3adb Clean up and simplify tmux command argument parsing.
Originally, tmux commands were parsed in the client process into a
struct with the command data which was then serialised and sent to the
server to be executed. The parsing was later moved into the server (an
argv was sent from the client), but the parse step and intermediate
struct was kept.

This change removes that struct and the separate parse step. Argument
parsing and printing is now common to all commands (in arguments.c) with
each command left with just an optional check function (to validate the
arguments at parse time), the exec function and a function to set up any
key bindings (renamed from the old init function).

This is overall more simple and consistent.

There should be no changes to any commands behaviour or syntax although
as this touches every command please watch for any unexpected changes.

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.

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.

071494d8fa Merge pane number into the target specification for pane commands. Instead of
using -p index, a target pane is now addressed with the normal -t window form
but suffixed with a period and a pane index, for example :0.2 or
mysess:mywin.1. An unadorned number such as -t 1 is tried as a pane index in
the current window, if that fails the same rules are followed as for a target
window and the current pane in that window used.

As a side-effect this now means that swap-pane can swap panes between different
windows.

Note that this changes the syntax of the break-pane, clear-history, kill-pane,
resize-pane, select-pane and swap-pane commands.

2b331084b4 Add an additional heuristic to work out the current session when run from the
command line. The name of all slave ptys in the server is known, so if the
client was run on a tty, look for any sessions containing that tty and use the
most recently created.

This is more reliable than looking at $TMUX if windows have been moved or
linked between sessions.

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.

f7df0bac96 Tidy the target parsing code a bit and correct the behaviour so that as before
a string with no colon as a target window is first looked up as a window then
as a session, noted by Iain Morgan.

Also attempt to clarify the description of the target specification in the man
page.
