Also:
* Move SetMinimumLogLevel() into MojoLogger itself. (This is somewhat
  unfortunate, since may not be thread-safe -- in particular, when
  sharing a copy of base's logging as in a component=shared_library
  build, it becomes blatantly unsafe. Thus it's of slightly dubious
  value. But it's where it belongs logically. Of course, sharing a log
  level across applications that are cohabiting a process is dubious.
  Avoiding this would mean at least layering a log level on top of
  Chromium's.)
* Allow the (standalone) Environment's choices for default AsyncWaiter
  and/or Logger to be overridden.
