Bug 547304 - [cleanup] Fix wrong space/tab indentationI20190626-0720I20190625-1800I20190625-0535I20190624-1800

This change fixes space or mixed tab/space indentations in all Java
files. This also includes two or three space indentations and even fix
most stray single spaces in indentations.
The change includes only whitespace formatting and no code changes.
