[PATCH] Bug fix for #1678

[Hiro Takahashi]

This is the fix for ServletInputStream.read() bug.
    #1678: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=1678
The change is in Ajp13ConnectorRequest.java. This one is obviously
the one which has not been tested with a binary data.
I made this patch for 3.2.1.
