Refactor ModularArithmetic into Zmod, expand Decidable
ModularArithmetic now uses Algebra lemmas in various places instead of
custom manual proofs. Similarly, Util.Decidable is used to state and
prove the relevant decidability results.
Backwards-incompatible changes:
F_some_lemma -> Zmod.some_lemma
Arguments ZToField _%Z _%Z : clear implicits.
inv_spec says inv x * x = 1, not x * inv x = 1
