i#2369 code style checks: Add checks for macro indentation.

Created by: fhahn

This patch adds a TCL vera++ script to check macros are indented properly. It does ignore header include guards ending with H. This patch also addresses a bunch of violations. Unfortunately there are a lot of violations, so I had to ignore plenty of violating files to get this ready for review.
