[evolution-kolab] libekolabutil: added CamelIMAPXStream helper function

[Christian Hilberg <chilberg src gnome org>]

commit 76c939a29faf2e793c70949c81a35f0b77398754
Author: Christian Hilberg <hilberg kernelconcepts de>

    libekolabutil: added CamelIMAPXStream helper function
    
    * added function to test whether a CamelIMAPXStream
      is "at end of stream"
    * camel_stream_eos() always returns TRUE for a
      CamelIMAPXStream for some reason, so we need
      to read a token, check it and write it back
      to the stream...
