Enable one to import both stdpp's base and ssrfun. Note that (f x.1) now parses as (f (fst x)) rather than (fst (f x)). (This change affects one proof in Iris.)

This gets rid of the old hack to have specific notations for pairs up to a fixed arity, and moreover allows to do fancy things like: ``` Record test := Test { t1 : nat; t2 : nat }. Definition foo (x : option test) : option nat := ''(Test a1 a2) ← x; Some a1. ```

 Name all variables that we refer to.  Put types in definitions.

This follows the associativity in Haskell. So, something like f <$> g <$> h Is now parsed as: (f <$> g) <$> h Since the functor is a generalized form of function application, this also now also corresponds with the associativity of function application, which is also left associative.

This is similar to `f_equal/=`.

We prove that various types are infinite, notably:  nat, N, positive and Z;  string (using prettyprinting of nat);  option, with an infinite element type;  list, with an inhabited element type. Furthermore, we instantiate Fresh for strings.

This implements a simple linear search for fresh elements.

This generalizes Fix_unfold to a setoid setting. In particular, we can use this to unfold multiargument fixpoints without requiring functional extensionality.

Infinity is described by having an injection from nat.
