Memory corruption in overflow in Binary*OutputStream

Hi, Igniters.
I've came across JVM crush recently. And after investigations I've found
Binary(Off)HeapOutputStream does not check correctly for overflow of the
capacity counter and can write to an unallocated memory.
Please take a look at https://issues.apache.org/jira/browse/IGNITE-14687

Best regards,
Sergey Kosarev.
