Bump more deps.

This is *almost* everything surfaced by a command like the one I used for some of our libraries, as in CL 348090041:

```
( for F in $(find -name pom.xml); do ( mvn org.codehaus.mojo:versions-maven-plugin:2.8.1:update-properties org.codehaus.mojo:versions-maven-plugin:2.8.1:use-latest-releases -f $F -DgenerateBackupPoms=false ); done )
```

Note that this covers *dependencies* but not *plugins*.

Note also that I had to revert some updates because of breakages:

- EasyMock
- Hamcrest
- test-parameter-injector because it transitively updated protobuf
- conceivably other things that I've forgotten

Fixes #2901
