3034a71488 Let's see if anyone screams about not being able to specify $TMPDIR
for their tmux sockets.

(Over the years, I have seen $TMPDIR set up worse than /tmp many times,
and don't know how this practice infected other parts of the system.
Nothing uses tmpdir(3), nor a huge-temporary-file program like sort.)

c1ccefc62d We accidentally haven't been using $TMUX to work out the session for a
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.

282c5f9644 Alter how tmux handles the working directory to internally use file
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.

e4dc1568ce Don't treat TMUX_TMPDIR as a potential file
The point of setting TMUX_TMPDIR is to then make any labels from -L go
to that directory.  In the case of makesocketpath() with no TMUX_TMPDIR
set, would set both the path and the default socket to a file.  The
checking of the permissions on the file worked fine in that case, but
when TMUX_TMPDIR is set, won't work on a directory.

This fixes the problem by ensuring the check on the permissions is
performed on directories only.

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.

535286c05a Drop the ability to have a list of keys in the prefix in favour of two

9a7cde0c9b Two new options:
- server option "exit-unattached" makes the server exit when no clients
  are attached, even if sessions are present;

- session option "destroy-unattached" destroys a session once no clients
  are attached to it.

These are useful for preventing tmux remaining in the background where
it is undesirable and when using tmux as a login shell to keep a limit
on new sessions.

42e2413978 Setting the cmdlist pointer in the bind-key to NULL to prevent it being freed
after the command is executing is bogus because it may still be needed if the
same command is going to be executed again (for example if you "bind-key a
bind-key b ..."). Making a copy is hard, so instead add a reference count to
the cmd_list.

While here, also print bind-key -n and the rest of the flags properly.

abf3a5d50e Initial changes to move tmux to libevent.
This moves the client-side loops are pretty much fully over to event-based only
(tmux.c and client.c) but server-side (server.c and friends) treats libevent as
a sort of clever poll, waking up after every event to run various things.

Moving the server stuff over to bufferevents and timers and so on will come
later.
