AbstractIoSession.increaseWrittenBytesAndMessages does not update writtenBytes for FileRegion
---------------------------------------------------------------------------------------------

                 Key: DIRMINA-525
                 URL: https://issues.apache.org/jira/browse/DIRMINA-525
             Project: MINA
          Issue Type: Bug
          Components: Core
         Environment: jdk1.6.0_03 Linux x64
            Reporter: Geoff Cadien
             Fix For: 2.0.0-M1


AbstractIoSession.increaseWrittenBytesAndMessages only updates writtenMessages and not writtenBytes
for a FileRegion.  
Below is a patch that fixes the problem but I'm not sure if it is correct.  When the WriteRequest
contains an IoBuffer a check is made to see if the IoBuffer has any remaining bytes and only
updates writtenBytes if it does.  I've never seen this method called when only part of a FileRegion
is sent and I'm sure how it could be because it seems that increaseWrittenBytesAndMessages
is only called from fireMessageSent.
