tor/changes/ticket25927.2

  o Code simplification and refactoring:
    - Remove our previous logic for "cached gettimeofday()" -- our coarse
      monotonic timers are fast enough for this purpose, and far less
      error-prone. Implements part of ticket 25927.
Remove the "cached gettimeofday" logic. Previously were using this value to have a cheap highish-resolution timer. But we were only using it in one place, and current dogma is to use monotime_coarse_t for this kind of thing. 2018-04-26 16:24:33 +02:00			`o Code simplification and refactoring:`
