Prepare snap server client test scenario cont2 (#1487)
* Clean up some function prototypes

why:
  Simplify polymorphic prototype variances for easier maintenance.

* Fix fringe condition crash when importing bogus RLP node

why:
  Accessing non-list RLP entry as a list causes `Defect`

* Fix left boundary proof at range extractor

why:
  Was insufficient. The main problem was that there was no unit test for
  the validity of the generated left boundary.

* Handle incomplete left boundary proofs early

why:
  Attempt to do it later leads to overly complex code in order to prevent
  looping when the same peer repeats to send the same incomplete proof.

  Contrary, gaps in the leaf sequence can be handled gracefully with
  registering the gaps

* Implement a manual pivot setup mechanism for snap sync

why:
  For a test scenario it is convenient to set the pivot to something
  lower than the beacon header from the consensus layer. This does not
  need rely on any RPC mechanism.

details:
  The file containing the pivot specs is specified by the
  `--sync-ctrl-file` option. It is regularly parsed for updates.

* Fix calculation error

why:
  Prevent from calculating negative square root
