    drbd plugin: improve header lines identification
    
    Recent DRBD versions display more detailed build information in
    `/proc/drbd`, which caused the header identification to fail.
    
    Comparing the first part of each line against all known header prefixes
    will hopefully make this more robust.
    
    Fixes #1514

    df: remove legacy code skipping "rootfs" monitoring
    
    3512bb1 added code to skip duplicate reporting of `rootfs` mounted on `/`.
    f9c1c5b and f0398d0 added generic code to skip any volume mounted twice.
    
    Depending on the order of the entries in `/etc/mtab`, reporting for `/` was
    entirely skipped.
    
    This patch basically reverts the first, non-generic patch, as it's
    superseded by the 2 others.
    
    Fixes #1402

    docs: Add info about mode7 requirement for ntpd
    
    Since ntpd-4.2.7p230 "mode 7" requests are ignored by default, and
    that's what ntpd plugin uses currently. The ntp daemon must be
    explicitly configured to enable mode7 requests.
    This patch adds short information about that to collectd.conf manpage.
