Add a python script to merge the CSV files, dealing with the fact that the source columns may differ due to the annotation properties present in the source. Add this new file and the existing greylist.txt files as dependencies of the 'dist' target, so that they appear as artifacts on the build server. This allows them to be processed later by reading them from the build server. Test: m out/target/common/obj/PACKAGING/hiddenapi-greylist.csv Bug: 117314178 Change-Id: Ib9e5da90e4c32333a3f4f02ee7f159f77086ae5e
