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,
aiRowLogEst and zName are removed from Index. All usages
of this fields changed to usage of corresponding index_def
or index_def->opts fields.
index_is_unique(), sql_index_collation() and
index_column_count() are removed with calls of
index_def corresponding fields.
Also there is small change in user-visible behavior:
before the patch a statement like
CREATE TABLE t1(a,b, PRIMARY KEY(a,b), UNIQUE(a,b))
created only one constraint index (for primary key)
and no index for UNIQUE constraint (since it is upon the
same columns), neither it is named or non-named constraint.
After the patch index will be always created for named
constraints. It is a temporary solution. In future it's
preferable not to create an index, but to make some record
in _constraints space that this named unique constraint
implemented with the same index as primary key constraint.
Closes: #3369, #3498
