Daniel Kulp resolved AVRO-2179.
-------------------------------
       Resolution: Fixed
         Assignee: Daniel Kulp
    Fix Version/s: 1.9.0

For 1.9.0, I've added a system property of "org.apache.avro.limits.string.maxLength" that can be used to set a maximum string length to read for Utf8 strings.

> Recentlly I use avro find it has this problem:The memory suddenly explode and trigger the fullgc, So I dump the memory file. And then I use jvisualvm tool to analysis I found a org.apache.avro.util.Utf8 object and the bytes array length was over 1610470037.
> The method of readInt() shouldn't over limit, So I think it should be restricted.
