title: How to change the buffer limit in Google's protobuf?
body: <p>I'm getting this warning and an error afterwards when I try to parse a large message. I know than 64MB which is the default limit. I am using message.ParseFromIstream now. Does any one know to get access to CodedInputStream object to call the SetTotalBytesLimit function? or any other way to solve this problem? </p>
  
  <blockquote>
    <p>Reading dangerously large protocol message. If the message turns out
    to be larger than 67108864 bytes, parsing will be halted for security
    reasons. To increase the limit (or to disable these warnings), see
    CodedInputStream::SetTotalBytesLimit() in
    google/protobuf/io/coded_stream.h.</p>
