/* 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 entry due to needing more, if that oldest
 *    entry was missing, it is now considered lost and the lost counters
 *    are incremented (and missing counters decremented)
 *  If we receive an entry 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 entry 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 entries 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 entries 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 entries 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 entries 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 entry 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
 *
 * The sequence fields are checked for validity when the message arrives
 * Sequence order checking of reload lines are done immediately
 * Checking of ckpool lines isn't done until after the reload completes
 *  This solves the problem of the overlap from reload to queue
 *   If we stop the reload when we first match the queue, there's the issue
 *    that data order in the reload file may not match the data order in the
 *    queue and thus we could lose a record that is late in the reload file
 *    but was before the queue start
 *   To solve this unlikely (but not impossible) issue we reload all reload
 *    files to the end and then sequence process the queued data after the
 *    reload completes
 *   This however produces another (solvable) problem that the queue start
 *    may be stale when we finally complete the reload
 *   To handle this we keep a list of all lost records in the reload and check
 *    the stale queue records against those to see if we found them
 *    If a queue line is lower than minseq then that's a sequence error
 *    If a queue line is stale but above minseq, we check if it is in the
 *     lost list and then report it as recovered (and process it)
 *    If it wasn't lost then it's an expected duplicate and ignored
 *    Once the queue exceeds the reload maxseq, the lost records are no longer
 *     needed and are discarded */
