Flush the records staging buffer periodically (#7193 )

- Staging buffer is flushed every 500ms. In cases where the result
  records are slowly generated (e.g. when a where condition
  matches very few records), this change causes the server to send
  results even though the staging buffer is not full.

- Refactor messageWriter code to use simpler channel based
  co-ordination instead of atomic variables.

Use a buffer to collect SQL Select result rows (#7158 )

Batching records into a single SQL Select message in the response
leads to significant speed up as the message header overhead is made
negligible.

This change leads to a speed up of 3-5x for queries that select many
small records.
