    Add/use a new get_ctrl_dir() function to query the SBBSCTRL env var and if · b236be71

    not set (or blank), use the default ("/sbbs/ctrl") and print a warning to
    stderr. This resolves a FAQ for sysops that struggle with setting the SBBSCTRL
    env var, but do have sbbs install in /sbbs or a symlink from /sbbs to where
    sbbs is actually installed.
    Note: this function is different than the one previously defined in getctrl.c
    but never used. If/when we ever really need to support PREFIX, then perhaps
    we'll use that one (which copies a string to a buffer).
