      Fix issue #98. · e17ac4ad
      Robbert Krebbers authored
      We used to normalize the goal, and then checked whether it was of
      a certain shape. Since `uPred_valid P` normalized to `True ⊢ P`,
      there was no way of making a distinction between the two, hence
      `True ⊢ P` was treated as `uPred_valid P`.
      
      In this commit, I use type classes to check whether the goal is of
      a certain shape. Since we declared `uPred_valid` as `Typeclasses
      Opaque`, we can now make a distinction between `True ⊢ P` and
      `uPred_valid P`.

      Generalize update tactics into iMod and iModIntro for modalities. · fc30ca08
      Robbert Krebbers authored
      There are now two proof mode tactics for dealing with modalities:
      
      - `iModIntro` : introduction of a modality
      - `iMod pm_trm as (x1 ... xn) "ipat"` : eliminate a modality
      
      The behavior of these tactics can be controlled by instances of the `IntroModal`
      and `ElimModal` type class. We have declared instances for later, except 0,
      basic updates and fancy updates. The tactic `iMod` is flexible enough that it
      can also eliminate an updates around a weakest pre, and so forth.
      
      The corresponding introduction patterns of these tactics are `!>` and `>`.
      
      These tactics replace the tactics `iUpdIntro`, `iUpd` and `iTimeless`.
      
      Source of backwards incompatability: the introduction pattern `!>` is used for
      introduction of arbitrary modalities. It used to introduce laters by stripping
      of a later of each hypotheses.

      Rename rvs -> bupd (basic update), pvs -> fupd (fancy update). · 1b85d654

      And also rename the corresponding proof mode tactics.
