to fix a potential race, and add some extra logging.

while and in fact it is less useful that using the client ttyname. So
don't bother and don't pass it from the client. If we need it in future
it is in c->environ.

descriptors rather than strings.
- Each session still has a current working directory.
- New sessions still get their working directory from the client that
created them or its attached session if any.
- New windows are created by default in the session working directory.
- The -c flag to new, neww, splitw allows the working directory to be
overridden.
- The -c flag to attach let's the session working directory be changed.
- The default-path option has been removed.
To get the equivalent to default-path '.', do:
bind c neww -c $PWD
To get the equivalent of default-path '~', do:
bind c neww -c ~
This also changes the client identify protocol to be a set of messages rather
than one as well as some other changes that should make it easier to make
backwards-compatible protocol changes in future.

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.

sent to stdin before it is needed, which can be inconvenient (eg pasting
commands). Instead, start with stdin disabled and reuse MSG_STDIN from
server->client to mean that stdin should be enabled. Based on a diff

integrate with other terminal emulators and should allow some other
things to be made simpler later. More to come so doesn't do much yet and

handling them in the server, handle them in the client and pass buffers
over imsg. This is much tidier for some upcoming changes and the
performance hit isn't critical.
The tty fd is still passed to the server as before.
This bumps the tmux protocol version so new clients and old servers are
incompatible.

commands can directly make use of them. This means that load-buffer and
save-buffer can have "-" as the file to read from stdin or write to stdout.
This is a protocol version bump so the tmux server will need to be restarted
after upgrade (or an older client used).

starting tmux from .xinitrc.
One of the very few things the server relies on the client for now is to
pass through a message on SIGWINCH, but there is a condition where
potentially a SIGWINCH may be lost during the transition from unattached
(main.c) to attached (client.c). So trigger a size change immediately
after the client installs its SIGWINCH handler.
Also, when the terminal is resized, reset the scroll region and cursor
position. Previously, we were clearing our saved idea of these, but in
fact some terminals do not reset them on resize, so this caused problems
during redraw.
While here make a resize to the same size not cause a redraw and rename
the tmux.out output log file to include the tmux PID.
