Having a standard tool for formatting saves reviewers' valuable time. google-java-format is Google's standard formatter and is somewhat inspired by gofmt[1]. This commit formats everything using google-java-format version 1.2. The downside of this one-off formatting is breaking blame. This can be somewhat hacked around with a tool like git-hyper-blame[2], but it's definitely not optimal until/unless this kind of feature makes its way to git core. Not in this change: * Tool support, e.g. Eclipse. The command must be run manually [3]. * Documentation of best practice, e.g. new 100-column default.
