* Structural recursion can now be explicitly requested using
```
termination_by structural x
```
in analogy to the existing `termination_by x` syntax that causes well-founded recursion to be used.
(#4542)
* The `termination_by?` syntax no longer forces the use of well-founded recursion, and when structural
recursion is inferred, will print the result using the `termination_by` syntax.
* Mutual structural recursion is supported now. This supports both mutual recursion over a non-mutual
data type, as well as recursion over mutual or nested data types:
```lean
mutual
def Even : Nat → Prop
| 0 => True
| n+1 => Odd n
def Odd : Nat → Prop
| 0 => False
| n+1 => Even n
end
mutual
inductive A
| other : B → A
| empty
inductive B
| other : A → B
| empty
end
mutual
def A.size : A → Nat
| .other b => b.size + 1
| .empty => 0
def B.size : B → Nat
| .other a => a.size + 1
| .empty => 0
end
inductive Tree where | node : List Tree → Tree
mutual
def Tree.size : Tree → Nat
| node ts => Tree.list_size ts
def Tree.list_size : List Tree → Nat
| [] => 0
| t::ts => Tree.size t + Tree.list_size ts
end
```
Functional induction principles are generated for these functions as well (`A.size.induct`, `A.size.mutual_induct`).
Nested structural recursion is still not supported.

* A bugfix in the structural recursion code may in some cases break existing code, when a parameter
of the type of the recursive argument is bound behind indices of that type. This can usually be
fixed by reordering the parameters of the function (PR #4672)
