resolved conflicts for merge of 7f45b2e9 to master

Explanation of conflict:
- I did modify master a while go to support new
  source_prop_template files.
- That CL was then manually merged into master-aosp
  and then auto-merged back to master.
- The template files were already in master.
- But the master version had 1 extra new line in each
  (to add gpu support).
- Thus conflict. CQFD.
