[Tarantool-patches] [PATCH v2 08/16] sql: resurrect sql_bind_parameter_count() function

[Nikita Pettik <korablev@tarantool.org>]

This function is present in sql/vdbeapi.c source file, its prototype is
missing in any header file. It makes impossible to use it. Let's add
prototype declaration to sql/sqlInt.h (as other parameter
setters/getters) and refactor a bit in accordance with our codestyle.

Need for #2592
