[Tarantool-patches] [PATCH v3 16/20] sql: move sql_stmt_busy() declaration to box/execute.h

[Nikita Pettik <korablev@tarantool.org>]

We are going to use it in box/execute.c and in SQL prepared statement
cache implementation. So to avoid including whole sqlInt.h let's move it
to relative small execute.h header. Let's also fix codestyle of this
function.

Needed for #2592
