Fails to build with protobuf 2.6.0

[sebastic]

osmosis fails to build on Debian unstable (as reported in ​Debian Bug #761562) where the protobuf package was recently upgraded from 2.5.0 to 2.6.0.

It looks like the parseUnknownField method has changed its signature:

Supporting protobuf 2.6.0 turned out to be easier than expected.

The code generated by osmosis-protoc.sh fixed the build failure.

[brett@…]

I've updated Osmosis to 2.6.0. I performed the same step as yourself, but I've checked the newly generated files into the source tree so that others can also use them.

At some point I'll need to generate a new release and upload the jars to Maven Central.
