    rtld: Add support for LD_LIBRARY_PATH_FDS env variable
    This variable allows loading of shared libraries via directory descriptors
    rather than via library paths. if LD_LIBRARY_PATH_FDS=3:4:12, the
    directories represented by file descriptors 3, 4, and 12 will be searched
    for shared libraries before the normal path-based mechanisms are used.
    This allows the execution of unpriviledge binaries from within a Capsicum
    sandbox even if they require shared libraries.  Note that Capsicum is not
    available on DragonFly yet.
    While here, adjust whitespace and rearrange a bit to minimize differences
    with FreeBSD rtld.
