NET throws a ProtocolViolationException when you attempt to write more bytes
to the request stream than the specified ContentLength. We currently allow

Reproducible: Always

Steps to Reproduce:
Compile and run the following code:

using System;
using System.IO;
using System.Net;

class Program
    static void Main ()
        HttpWebRequest req = (HttpWebRequest) WebRequest.Create (new Uri
        req.Method = "POST";
        req.ContentLength = 2;

        byte [] buffer = new byte [] { 0x2a, 0x2c, 0x1d };

        Stream rs = req.GetRequestStream ();
        rs.Write (buffer, 0, 3);

Actual Results:  
No exception.

Expected Results:  
Unhandled Exception: System.Net.ProtocolViolationException: Bytes to be written
to the stream exceed the Content-Length bytes size specified.
   at System.Net.ConnectStream.InternalWrite(Boolean async, Byte[] buffer,
 offset, Int32 size, AsyncCallback callback, Object state)
   at System.Net.ConnectStream.Write(Byte[] buffer, Int32 offset, Int32 size)
   at Program.Main()

I'll add a test named "GetRequestStream_Write_Overflow" to
HttpWebRequestTest.cs, and mark it NotWorking.
