* Adjust TS and cycles when adjusting start.
Chasing some AddPacket errors across relay.
Noticed that in one case the start/end sequence was flipped.
There is a known issue of it happening with resync.
Unclear if this instance was due to resync or not.
The start was close to the edge (64513). So, thought maybe
adjust at start and noticed that it needs to maybe increase
cycle count if start is wrapping back. In this case, the
start is 1000 before wrap point. So, may not be a wrap back
issue, but addressing what I found anyway.
* fix test
* Fix unwrap
An out-or-order packet wrapping back after a wrap around had already happened
was not using proper cycle ounter to calculate unerapped value.
* update mediatransportutil

* fix another test compile
* Adding TODO notes
* chainID -> chainIdx
* do not need to check for switch up point when using chains, as long as chain integrity is good, can switch
* more comments
* address comments
