    Branch: master
    Fix Description: If running as non-root, look for the initconfig scripts/files
    in ~/.dirsrv.  If the INITCONFIGDIR env. var. is set, use that and do not
    look anywhere else.  Cannot depend on the value of $USER - must use id to
    determine the effective user id.  Also fixed a problem with return value
    handling - the if test changes the value of $?, so have to save the value
    just after starting the instance.
    Platforms tested: RHEL6 x86_64
