* node/approval-voting: test for invalid validator index in assignments
This commit adds a unit test to show that, currently, validator indexes
greater than n_validators (or the length of the approvals bitvector) are
counted in n_assignments. In the subsequent commit we will correct this
behavior.
* node/approval-voting: ignore invalid validator indexes in n_assignments
This commit ignores any validator assignments whose index is beyond
n_validators. Without this check, an improperly crafted assignment would
be counted towards the approval.
It still remains that n_assignments and count_no_shows inspect the
number of validators and approvals, respectively. Ideally we would
add greater safety around ensuring these two values cannot differ.
* node/approval-voting: extract and test count_no_shows method
This commit extracts no_show computation into a pure function so that it can be
extensively unit tested.
* node/approval-voting: ignore invalid validator indexes in count_no_show
Previously indexes that were past the length of the approvals bitvector
would contribute to the no_show count or the next_no_show value. This
commit changes the behavior to ignore garbage values.
* node/approval-voting: add comment for next_no_show adding clock_drift
* node/approval_checking: break out filled_tranch_iterator method
In the subsequent commit, we will begin to test this method in
isolation.
* node/approval-voting: fix tranche back-filling algorithm
Previously, this algorithm would generate duplicate, empty entries for
tranches (1..pre_end). This is caused because the initial value (0) for
gap_end is treated as the end of a prior tranche that wasn't actually
processed. The first pass thus would add (1..tranche) empty entries, in
addition to the (0..pre_end) empty entries chained at the end of the
method.
This is fixed by using the current tranche as the gap_start for the
first iteration, ensuring that the approval_entries_filled only produces
entries in the range (pre_end..post_start).

* Factor out runtime module into utils.
* Add maybe_authority information to `PeerConnected` event.
We already gather this information in authority discovery, so we might
as well share it with others.
This opens up an easy path to trigger validators differently from normal
nodes, e.g. for prioritization. This change has become more important
now, that we just connect to all validators and therefore just have a
long peer list without any information about those nodes.
* Test fix.
