[Tarantool-patches] [PATCH v3 11/20] sql: resurrect sql_bind_parameter_name()

[Nikita Pettik <korablev@tarantool.org>]

We may need to get name of parameter to be bound by its index position.
So let's resurrect sql_bind_parameter_name() - put its prototype to
sql/sqlInt.h header and update codestyle.

Need for #2592
