[PATCH v2 0/7] http: minor improvements

This patch series was generated on top of 'next'. It contains some general changes to http usage.

Some highlights:
  - add non-ff test cases to "dumb" http push test
  - separate init and cleanup of http from http-walker

Changes from v1 (based on comments from Clemens):
  - patch 3: don't say "remove condition", since we're actually enabling
    it.
  - patch 5: in keeping with separating http and http-walker, removed
    http_cleanup() from http-walker->cleanup().
  - patch 5: move http_cleanup() call after http-walker->cleanup(). This
    isn't really needed, but do this just in case http-walker->cleanup()
    does any http operations.
