lib/sh/util.sh: set_global_fds(): moved stdlog fd setup to separate setup_log_fd() function, which runs at a much higher log_level (5 instead of 3). because the stdlog fd setup statements themselves are logged to fd 2 (because fd 30 is not yet open), you normally don't want to display these, if you are using fd 2 for errors only and fd 30 for logging.

lib/sh/util.sh: command(): $cmd_log_fd: if not set, assume it's a script using util.sh (i.e. with log fd=$log_fd)

lib/sh/util.sh: set_global_fds(): also open stdlog logging stream on fd 30, and use this in the logging functions by setting $log_fd

lib/sh/util.sh: moved streams section before external commands echoing because command() uses set_fds

lib/sh/util.sh: moved echo_eval() to general command echoing section so it can be used by other echoing commands

lib/sh/util.sh: don't load new aliases after defining echo_stdout because it's no longer an alias

lib/sh/util.sh: load new aliases after defining echo_func

lib/sh/util.sh: .(): use "$FUNCNAME" like cd()

lib/sh/util.sh: .(): wrapped lines in the same way as cd()

lib/sh/util.sh: moved functions echoing section before other types of echoing so they can use echo_func()
