    Add RFC 8335 Definitions from Linux 5.13
    
    RFC 8335 defines the network utility PROBE, which builds off of the
    capabilities of Ping to query more detailed interface information from
    networking nodes.
    
    The definitions included in this patchset have been accepted into the
    linux net-next branch and will be included in Linux 5.13. This
    patchset adds the same definitions to the glibc for use in the
    iputils package.
    
    The relevant commits for the Linux definitions can be found here:
    https://github.com/torvalds/linux/commit/e542d29ca81d005651680a0a697b72ca13ddc4cc
    https://github.com/torvalds/linux/commit/750f4fc2a12f6632b5aa04526bf57fa06bfe8467
    
    These changes have been tested by running the glibc tests on x86_64
