Upgrade protobuf library to v2.6.1.

The previous commit was actually between v2.6.0 and v2.6.1. This CL
was created by generating a patch with:

git format-patch edc5994525c79cd1919859a370837a6ff7c8e308..v2.6.1

and applying this patch to the tree. The patch was clean except for
pom.xml, where the packaging type should have previously been changed
from "jar" to "bundle".

Reran ./configure && make -j12 check to regenerate configure script
and makefiles.
