IMPALA-1612: (shell) Upgrade sqlparse for bug fix

The only thing this commit does is upgrade sqlparse. The upgrade was
done by downloading and extracting the tarball, nothing else (such as
patching). The older version of sqlparse would parse

SELECT
'
;
'
;

into two statements. Neither statement is complete due to the open quote
and this would cause an infinite loop. The bug is already fixed in the
newest version of sqlparse.

+Analyzing the Parsed Statement
+==============================
+
+When the :meth:`~sqlparse.parse` function is called the returned value
+is a tree-ish representation of the analyzed statements. The returned
+objects can be used by applications to retrieve further information about
+the parsed SQL.
+
+
+Base Classes
+------------
+
+All returned objects inherit from these base classes.
+The :class:`~sqlparse.sql.Token` class represents a single token and
+:class:`~sqlparse.sql.TokenList` class is a group of tokens.
+The latter provides methods for inspecting it's child tokens.
