Attaching 3rd version of the patch. LazyColumnIterator is used both for SSTableScanners and
Memtable.
This version works for me.

> get_paged_slice doesn't reset the start column filter for the second returned row sometimes.
So instead of getting a slice:
> row 0: <start_column>...<last_column_in_row>
> row 1: <first column in a row>...<last_column_in_row>
> row 2: <first column in a row>...
> you sometimes get:
> row 0: <start_column>...<last_column_in_row>
> row 1: <start_column>...<last_column_in_row>
> row 2: <first column in a row>...
