code review 183140043: all: merge dev.garbage (d1238958d4ae) into default branch

all: merge dev.garbage (d1238958d4ae) into default branch

When we start work on Gerrit, ppc64 and garbage collection
work will continue in the master branch, not the dev branches.

(We may still use dev branches for other things later, but
these are ready to be merged, and doing it now, before moving
to Git means we don't have to have dev branches working
in the Gerrit workflow on day one.)
