Merge branch 'tc/http-cleanup'

* tc/http-cleanup:
  remote-curl: init walker only when needed
  remote-curl: use http_fetch_ref() instead of walker wrapper
  http: init and cleanup separately from http-walker
  http-walker: cleanup more thoroughly
  http-push: remove "|| 1" to enable verbose check
  t554[01]-http-push: refactor, add non-ff tests
  t5541-http-push: check that ref is unchanged for non-ff test
