    [BEAM-3081] NonNull by default for sdk/transforms and friends

    Follow this checklist to help us incorporate your contribution quickly and 
easily:
    
     - [ ] Make sure there is a [JIRA 
issue](https://issues.apache.org/jira/projects/BEAM/issues/) filed for the 
change (usually before you start working on it).  Trivial changes like typos do 
not require a JIRA issue.  Your pull request should address just this issue, 
without pulling in other changes.
     - [ ] Each commit in the pull request should have a meaningful subject 
line and body.
     - [ ] Format the pull request title like `[BEAM-XXX] Fixes bug in 
ApproximateQuantiles`, where you replace `BEAM-XXX` with the appropriate JIRA 
issue.
     - [ ] Write a pull request description that is detailed enough to 
understand what the pull request does, how, and why.
     - [ ] Run `mvn clean verify` to make sure basic checks pass. A more 
thorough check will be performed on your pull request automatically.
     - [ ] If this contribution is large, please file an Apache [Individual 
Contributor License Agreement](https://www.apache.org/licenses/icla.pdf).

    Also fixes a couple things masked by Jenkins outage. I expect current
