Subject: [PATCH] Modify Breakpad build scripts to pull Breakpad from its new
 git repository, and also add a `breakpad-taskcluster.sh` script that can be
 used to drive a Breakpad build in Taskcluster (initiated manually, for now).

+# This script can be used to build a new breakpad.tar.gz for Socorro
+# under Taskcluster. It is not currently used in an automated fashion,
+# you must manually submit a task to get a new build. The simplest way
+# is to paste the contents of the following here document into
+# the task-creator tool: https://tools.taskcluster.net/task-creator/
+#
+# This task will update a Taskcluster index if it succeeds, such that
+# the most recent tarball can be fetched from:
+# https://index.taskcluster.net/v1/task/project.socorro.breakpad.v1.builds.linux64.latest/artifacts/public/breakpad.tar.gz
+#
+# You must be a member of the `socorro` project in Taskcluster for this
+# task to work properly.
