    util: check for trailing characters in partition names
    
    The function which maps partition names to partition ids currently
    ignores trailing characters in the partition names. For example, the
    partition name "/vicepbogus" is currently considered a valid partition
    name ("/vicepbogus" maps to "bo" which is id 66). Although this is not a
    regression, it is problematic for several reasons.
    
    Firstly, this can lead to duplicate partition ids on the server, for
    example "/vicepbad" and "/vicepbar" both map to the same partition id
    ("ba" is id 52).
    
    Second, partitions are internally tracked by numeric id. The partition
    names are generated from numeric ids when reporting partition names.
    This means the trailing characters are lost when reporting the partition
    names. For example, vos reports the attached partition "/vicepbad" as
    "/vicepba".
    
    Third, it could be possible (but perhaps unlikely) in the future to
    extend the range of partition ids, so the trailing characters could
    become significant at that time.
    
    Finally, it could be confusing to admins that such partition names are
    attached by the fileserver. For example, "/vicepaa-backup" is attached
    and is used by the fileserver as partition id 26.
    
    This change adds a check for trailing characters in partition names in
    the volutil_GetPartitionID function, so it is more strict in what it
    accepts as a valid partition name.  That function will now return -1
    (illegal partition name) when trailing characters are found in
    partition names.
