d98336ad83 Fix incorrect columns order in subqueries of UNION 
Consider the following query:

    SELECT avgWeighted(x, y) FROM (SELECT NULL, 255 AS x, 1 AS y UNION ALL SELECT y, NULL AS x, 1 AS y)

Here is UNION from two SELECT queries
- `SELECT NULL, 255 AS x, 1 AS y`
- `SELECT y, NULL AS x, 1 AS y`

UNION queries matches columns by positions, not names, so the following
columns should be used by `avgWeighted()`:
- `255 AS x,  1 AS y`
- `NULL AS x, 1 AS y`

Result types of arguments should be:
- `x Nullable(UInt8)`
- `y UInt8`

And in case of UNION query is a subselect itself, it will return only
required columns, for the example above it needs only `x` and `y`.
For this it will get positions of these arguments from the first query,
and then use those positions to get required column names from the
second query (since there is no ability to get columns by positions
instead of names internally), and due to duplicated columns the second
query will return (`y`, `x`) not (`x`, `y`), and this will make the
result incorrect:

    EXPLAIN header = 1, optimize = 0, actions=1 SELECT avgWeighted(x, y) FROM (SELECT NULL, 255 AS x, 1 AS y UNION ALL SELECT y, NULL AS x, 1 AS y)

    Aggregates:
        avgWeighted(x, y)
          Function: avgWeighted(Nullable(UInt8), UInt8) → Nullable(Float64)
          Arguments: x, y
          Argument positions: 0, 1
      Expression (Before GROUP BY)
      Header: x UInt8
              y Nullable(UInt8)
      ...
      Union
      Header: x UInt8
              y Nullable(UInt8)
        Expression (Conversion before UNION)
        Header: x UInt8
                y Nullable(UInt8)
        Expression (Conversion before UNION)
        Header: x UInt8
                y Nullable(UInt8)

And the query itself fails with an error:

    Logical error: 'Bad cast from type DB::ColumnVector<char8_t> to DB::ColumnNullable'.

_NOTE: `avgWeighted()` here is required to trigger `LOGICAL_ERROR`_

ee0f2651ee Revert "Fix converting types for UNION queries (may produce LOGICAL_ERROR)" 
This fix is incorrect, and it introduce new issues, in particular it
may breaks UNION queries w/o column aliases, i.e.:

    SELECT a, b, c FROM (SELECT 3 AS a, 2147483647 AS b, 1048575 AS c UNION ALL SELECT -2, NULL, -2) AS js1 ORDER BY a

Don't use std::unique_lock unless we have to 
Replace where possible by std::lock_guard which is more light-weight.
