Test instrumentation of Hash nodes with parallel query.
Commit 8526bcb2df76d5171b4f4d6dc7a97560a73a5eff fixed bugs related
to both Sort and Hash, but only added a test case for Sort. This
adds a test case for Hash to match.

Try again to fix accumulation of parallel worker instrumentation.
When a Gather or Gather Merge node is started and stopped multiple
times, accumulate instrumentation data only once, at the end, instead
of after each execution, to avoid recording inflated totals.

Re-fix wrong costing of Sort under Gather Merge.
Commit dc02c7bca4dccf7de278cdc6b3325a829e75b252 changed this call
to create_sort_path() to take -1 rather than limit_tuples because,
at that time, there was no way for a Sort beneath a Gather Merge
to become a top-N sort.
Later, commit 3452dc5240da
Mark a few parallelism-related variables with PGDLLIMPORT.

Add libpq connection parameter "scram_channel_binding"
This parameter can be used to enforce the channel binding type used
during a SCRAM authentication. This can be useful to check code paths
where an invalid channel binding type is used by a client and will be
even more useful to allow testing
