New issue 592 by OstreamOutputStream with ofstream loses data from the tail

What steps will reproduce the problem?
1. Use an OstreamOutputStream with an ofstream as the underlying IO stream.
2. Write data that is not aligned to the buffer boundary for the ofstream implementation. This happens surprisingly often for me (e.g. try writing somewhere between 8192 and 8192+127 bytes). It happens even with fewer bytes. 3. Alternatively, the attached patch adds a test to which fails without the attached fix.

What is the expected output? What do you see instead?
Expected output is that OstreamOutputStream should work regardless of the amount of data written. The attached fix addresses this issue by adding a Flush operation to the underlying implementation.

Protobuf version 2.5.0
