Problem with copying constructor and unbuffered TCPStream

[Ian Campbell]

Hello David et al,
    I discovered a problem with the using the copy constructor and TCPStream
with a buffer size of < 2. This is because the copy constructor does not
make gbuf and pbuf NULL when copying which in turn causes the destructor to
segmentation fault. Here is a patch for this:

  if(size < 2)
  {
   bufsize = 1;
+  gbuf = pbuf = NULL;
   return;
  }

Cheers,
