    locale.sh: add support for user-specific locale.conf
    
    We use the first configuration file we find out of:
    
     * $XDG_CONFIG_HOME/locale.conf
     * /etc/locale.conf
     * /etc/rc.conf
    
    All subsequent config files are ignored. E.g., an emtpy /etc/locale.conf
    means that LOCALE from rc.conf is ignored.
    
    Note that currently $XDG_CONFIG_HOME is unlikely to be set when
    locale.sh is sourced, so it will not have any effect. In the future this
    might change, so we kept it in.
    
    This will easily allow users to set one locale to be used for
    daemons/boot and a separate one to be used for users consoles etc.
    
    This eliminates the need for DAEMON_LOCALE, so remove that
    functionality. A post-install note will be added.
    
    The constraints that led to this suggestion:
    
    1) The default locale should work even if locale-gen has not been run,
       i.e., it should be "C".
    2) It is common to want the system locale to be "English", which a
       priori "C" satisfies. However, "C" is not UTF-8, which causes issues
       when the user locale is in UTF-8 (as it is the system locale that
       configures the console mode).
    3) Users might (and often do) want a different locale than what is used
       system-wide. Moreover, different users might want different locales.
