#2646: [nine] Asynchronous Steps

-------------------+--------------------
 In 0.8.x, build steps are *very* synchronous.
 Nine introduces "new-style" steps that call methods asynchronously and do
 not expect easy access to the full text of logfiles.
 However, there's also substantial work in place to maintain backward
 compatibility - at least temporarily - for old-style steps.
 This project is mostly in Dustin's head.
 Here are the remaining bits:

  * implement new-style compatibility on master, as well
   * just return defer.succeed(..); no need for wrappers for old-style
 steps
   * include enough checks that users can be confident their new-style
 steps are OK

  * change backend to use data API
   * persist properties at build or step finish
   * change addLog to return a ProcessLog instance

  * ensure that new-style steps don't see any removed methods or old
 behaviors
   * all of the stuff listed as removed in the relnotes
   * `createSummary`, `log_eval_func`, among others

  * rewrite steps to new style
   * but not !ShellCommand, yet, since user classes derive from it
   * merge rewrites to master
   * remove `step_status` for statistics

  * update documentation
   * lots of changes in `customization.rst`
   * `cfg-statustargets.rst` references `getText`
