enforce max line length at 118

gitlab's diff views wrap badly when lines are longer than 118.  Android
Studio places a grey line in the UI at 120.

@SuppressWarnings("LineLength") is added to a bunch of files to prevent
making this commit huge.  People can remove that as they work on those
files, and fix the issues then.

I also ran Android Studio's default Ctrl-Alt-L code formatter, where it was
easy to do, and I was already in the file.
