Don't try to change the window name unless the pid of the process chosen has changed. Reduces CPU use. osdep-* stuff is a bit horrible now but there we go :-/.

Looking up argv[0] is expensive, so just use p_comm for the window name which is good enough. Also increase name update time to 500 ms.

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 use some platform specific code 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.
