Ok.

Fixed.

Ok, fixed in all the places.

Refactoring mistake. Made total_sql_str_size output parameter.

Ok. Fixed.

Because it is called in create_index before set_index_def invocation. Anyway I got your point, add call in set_index_def

Okay, I removed coll_array, coll_id_array and aiColumn.

Create_sql() function seems to be separate piece of string building logic. SQL expression
can be generated during part initialising, but IMHO it will mess the code.

Patch:
From 9fe52af99c305aaf381de3b5414ab5fb03f65817 Mon Sep 17 00:00:00 2001
From: Ivan Koptelov <ivan.koptelov@tarantool.org>
Date: Thu, 7 Jun 2018 19:42:16 +0300
Subject: [PATCH] sql: add index_def to Index
Now every sqlite struct Index is created with tnt struct
index_def inside. This allows us to use tnt index_def
in work with sqlite indexes in the same manner as with
tnt index and is a step to remove sqlite Index with
tnt index.
Fields coll_array, coll_id_array, aiColumn, sort_order
and zName are removed from Index. All usages of this
fields changed to usage of corresponding index_def
fields.
index_is_unique(), sql_index_collation() and
index_column_count() are removed with calls of
index_def corresponding fields.
Closes: #3369
Github branch: https://github.com/tarantool/tarantool/tree/sb/gh-3369-use-index-def-in-select-and-where
