* Add gradle-tools subproject
* Add Gradle buildscripts to the related projects
* Remove the projects from the libraries pom.xml
* Move AndroidGradleWrapper.groovy to separate source root
* Changed artifact dependencies to project dependencies where needed
* Extract common configuration into commonConfiguration.gradle
* (convert functions to closures to be able to call them)
* Refactor DSL usage
* Replace `project.properties` with `findProperty`
* Unify Gradle wrapper between `libraries` and `gradle-tools`
(as a temporary solution, just made the wrapper files the same)
Writing source annotations enables incremental compilation for kapt2.
However they are not needed in bytecode, so we remove them when
copying classes.
