    stand - cleanup efi boot, fix corrupted free()
    
    * When freeing failed load resources, two of the resources allocated
      by boot services were being freed via free(), causing a panic.
    
    * Do not complain if a path component is not a directory, simply fail.
      Remove unnecessary noise from alternative config file tests.
    
    * Pre-assign NULL to pointers so they are NULL during error paths.
      Target procedures do not necessarily set them in error paths.
    
    * Display EFI errors in hex, not virtually unreadable decimal.
    
    * Cleanup for readability.
