+/* The aim of the sequence data is to identify and ignore duplicate records -
+ *  which should usually only be during a reload -
+ *  and to identify missing records when their sequence numbers are skipped
+ *
+ * If at any time there is a problem with a sequence number, an error is
+ *  reported, then the record being processed is simply processed normally by
+ *  the cmd_func() it was intended for - which may or may not produce other
+ *  processing error messages depending on the validity of the rest of the data
+ *
+ * Field explanation:
+ *  Normal sequence processing would be that we first get seq N, then N+1
+ *   then N+2 ... etc.
+ *   seqbase,minseq,maxseq are all set to the first N for the given sequence
+ *   maxseq is incremented to the current maximum N+x each time a record is
+ *   processed
+ *  If we get up to N+3 but it is unexpectedly followed by N+5, that means N+4
+ *   is currently missing - so it is flagged as missing by MISSFLAG=0 and the
+ *   missing counters are incremented - maxseq will now be N+5
+ *  Once we reach N+size we need to discard N and use it as N+size
+ *   and increment seqbase N
+ *   When we discard the oldest item due to needing more, if that oldest
+ *    item was missing, it is now considered lost and the lost counters
+ *    are incremented (and missing counters decremented)
+ *  If we receive an item N+x where N+x-maxseq>highlimit we reject it as high
+ *   and increment the high counters - this avoids creating a high bad sequence
+ *   number and flagging any missing sequence numbers, most likely incorrectly,
+ *   as lost in the range N to N+x-size
+ *  If we receive an item N-x i.e. less than seqbase N, then:
+ *   If maxseq-N = size then N-x is considered stale and the stale counters
+ *    are incremented since there's no unused items below N available
+ *    This shouldn't normally happen after we've received size seq numbers
+ *   Else maxseq-N is less than size, that means there are unused items below N
+ *    This will usually only be with a new sequence and the first seq was out
+ *     of order, before lower sequence numbers, thus maxseq should be close to
+ *     seqbase N and no where near N+size and there should be x unused below N
+ *    If there are x unused items below N then we can move seqbase down to N-x
+ *     after we flag all N-1,N-2,N-3..N-(x-1) as missing
+ *    Else there aren't enough unused items below N, then N-x is considered
+ *     stale and the stale counters are incremented
+ *
+ * timelimit is an early limit to flag missing sequence numbers as 'transient'
+ * Normally, if a missing item at N is later reused, it will be discarded and
+ *  reported as lost
+ * After the reload queue is complete, timelimit reports missing sequence
+ *  numbers early, as transient, if they have been missing for 'timelimit' but
+ *  not already lost
+ *  missing isn't decremented, since it is still treated as missing
+ * This is needed in case a size limit on a sequence means it may take a long
+ *  time before it reports messages as lost - this also means that after the
+ *  reload queue has cleared after ckdb startup, it will report the transient
+ *  missing sequence numbers shortly after the timelimit
+ * When they are later found or lost they will again be reported, this time as
+ *  found or lost */
