Big enum
2019-11-27Explicit `bigop` enumeration handlingGeorges Gonthier
Added lemmas `big_enum_cond`, `big_enum` and `big_enumP` to handle more explicitly big ops iterating over explicit enumerations in a `finType`. The previous practice was to rely on the convertibility between `enum A` and `filter A (index_enum T)`, sometimes explicitly via the `filter_index_enum` equality, more often than not implicitly. Both are likely to fail after the integration of `finmap`, as the `choiceType` theory can’t guarantee that the order in selected enumerations is consistent. For this reason `big_enum` and the related (but currently unused) `big_image` lemmas are restricted to the abelian case. The `big_enumP` lemma can be used to handle enumerations in the non-abelian case, as explained in the `bigop.v` internal documentation. The Changelog entry enjoins clients to stop relying on either `filter_index_enum` and convertibility (though this PR still provides both), and warns about the restriction of the `big_image` lemma set to the abelian case, as it it a possible source of incompatibility.

2019-11-22New generalised induction idiom (#434)Georges Gonthier
Replaced the legacy generalised induction idiom with a more robust one that does not rely on the `{-2}` numerical occurrence selector, using either new helper lemmas `ubnP` and `ltnSE` or a specific `nat` induction principle `ltn_ind`. Added (non-strict in)equality induction helper lemmas Added `ubnP[lg]?eq` helper lemmas that abstract an integer expression along with some (in)equality, in preparation for some generalised induction. Note that while `ubnPleq` is very similar to `ubnP` (indeed `ubnP M` is basically `ubnPleq M.+1`), `ubnPgeq` is used to remember that the inductive value remains below the initial one. Used the change log to give notice to users to update the generalised induction idioms in their proofs to one of the new forms before Mathcomp 1.11.
