Dissolve top level gitiles-* directories

The current layout of having gitiles-* directories with separate java
source trees dates back to the bad era of Maven, when this specific
layout was necessary to decompose the build into separate pom.xml files.

Moreover, src/{main,test}/java are also Maven artifacts, so that we go
even further and create three top level directories:

* java
* javatests
* resources
