Kevin O'Connor a619aacfc6 serialqueue: Further retransmit timing fixes
The first message always has a sync byte with it, so its size should
be one larger.  Also, the idle_time should always be the minimum time
that the message could be received, so it should always be reset to
eventtime on a retransmit.

Kevin O'Connor d469db84ee serialqueue: Allow a second nak after a retransmit
If a nak message causes a retransmission then also accept a second nak
message as long as it is for a sequence greater than the first nak.
This should allow faster retransmits when there are multiple
transmission errors in a small time period.

Kevin O'Connor 4655a6bfef serialqueue: Fix off-by-one error in retransmit sequence number tracking
Track the sequence number of the message last retransmitted (not the
sequence number of the next message to be transmitted).  This fixes a
small possibility of a valid nak not being honored.

Kevin O'Connor 61325c0a14 serialqueue: Improve timing of multiple retransmits
If a retransmit is triggered by a nak, then it is not necessary to
increase the rto.  The next retransmit time should be based on the
expected reception of the first retransmitted message, not the last.

Wait for any pending moves to be fully handled before exiting.  Make
sure the wait is done inside the "self.is_processing_data" check to
avoid infinite recursion.  Don't keep reading from the file while
waiting to exit.

Kevin O'Connor c7d0358c41 serialhdl: Rework mcu clock synchronization
The existing clock synchronization code has two flaws: intermittent
transmission latency during get_status requests can cause the
estimated clock to be too low, and the estimated clock calculation did
not take into account possible clock drift between samples.  The
former could potentially lead to "Timer too close" errors and the
latter could potentially lead to "Move queue empty" errors.

Rework the code to avoid the above problems.  It's not necessary to
estimate the micro-controller clock as an excellent estimate is
reported by the micro-controller (via the CLOCK_FREQ constant).
Account for a small drift from the reported value, and check on each
sample if the drift exceeds the expected limits.  With a good starting
estimated clock, only the offset needs to be calculated.  Use previous
offsets (and the estimated clock) in calculation of new offsets to
avoid intermittent latency from badly skewing the results.  Finally,
add an additional time offset of one millisecond to account for any
minor inaccuracies.
