124802e196 cql3: Add function to build view's select statement 
This patch adds an utility function that creates a raw select
statement from a set of columns and a where clause. It is intended to
be used to create the prepared select statement used by the view
class.

bd1e66f411 cql3: Allow renaming a column in a where clause 
This patch adds an utility function to rename a column occurring a
textual where clause. It is intended to change a view's where clause
when users alter the underlying base table.

To do this, we rely on functions that transform a textual where clause
into a set of relations, which allows to reliably rename the  column.
