Bug 1361661 - Part 1: Generate headers with process data from Processes.yaml. r=dexter Adding the Gecko enums to Processes.yaml allows us to generate mappings from ProcessID to GeckoProcessType. We generate string tables with the Telemetry process names, so we can use these names consistently throughout Telemetry.
