app/vlselect: do not show empty fields in query results
Empty fields are treated as non-existing fields by VictoriaLogs data model.
So there is no sense in returning empty fields in query results, since they may mislead and confuse users.

app/vlselect/logsql: clone the query with the current timestamp when performing live tailing requests in the loop
Previously the original timestamp was used in the copied query, so _time:duration filters
were applied to the original time range: (timestamp-duration ... timestamp]. This resulted
in stopped live tailing, since new logs have timestamps bigger than the original time range.

app/vlselect: consistently reuse the original query timestamp when executing /select/logsql/query with positive limit=N query arg
Previously the query could return incorrect results, since the query timestamp was updated with every Query.Clone() call
during iterative search for the time range with up to limit=N rows.

While at it, optimize queries, which find low number of matching logs, while spend a lot of CPU time for searching
across big number of logs. The optimization reduces the upper bound of the time range to search if the current time range
contains zero matching rows.

app/vlselect: follow-up for 451d2abf50
- Consistently return the first `limit` log entries if the total size of found log entries doesn't exceed 1Mb.
  See app/vlselect/logsql/sort_writer.go . Previously random log entries could be returned with each request.
- Document the change at docs/VictoriaLogs/CHANGELOG.md
- Document the `limit` query arg at docs/VictoriaLogs/querying/README.md
- Make the change less intrusive.

Revert "app/vlselect/logsql: use buffered writer in order to save syscalls when sending big amounts of data to clients"
This reverts commit c19048dc13.

Reason for revert: it has been appeared that the net/http.ResponseWriter is already buffered,
so there in no need in double bufferring
