    libxl: fork: Provide LIBXL_HAVE_SIGCHLD_SELECTIVE_REAP
    
    This is the feature test macro for libxl_childproc_sigchld_occurred
    and libxl_sigchld_owner_libxl_always_selective_reap.
    
    It is split out into this separate patch because: a single feature
    test is sensible because we do not intend anyone to release or ship
    libxl versions with one of these but not the other; but, the two
    features are in separate patches for clarity; and, this just makes
    reading the actual code easier.
