per https://code.google.com/p/protobuf/source/detail?r=50, the license on google-originated protobuf code was switched from Apache-2.0 to BSD-3-Clause (so-called "New BSD" license). update any of the google license statements to use this new license. per email with dave, drop the third clause on his BSD-3-Clause license, so this now becomes BSD-2-Clause. make sure to use consistent indentation and wrapping throughout.
