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. ```

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 provides significant robustness against looping type class search. As a consequence, at many places throughout the library we had to add additional typing information to lemmas. This was to be expected, since most of the old lemmas were ambiguous. For example: Section fin_collection. Context `{FinCollection A C}. size_singleton (x : A) : size {[ x ]} = 1. In this case, the lemma does not tell us which `FinCollection` with elements `A` we are talking about. So, `{[ x ]}` could not only refer to the singleton operation of the `FinCollection A C` in the section, but also to any other `FinCollection` in the development. To make this lemma unambigious, it should be written as: Lemma size_singleton (x : A) : size ({[ x ]} : C) = 1. In similar spirit, lemmas like the one below were also ambiguous: Lemma lookup_alter_None {A} (f : A → A) m i j : alter f i m !! j = None
↔ m !! j = None. It is not clear which finite map implementation we are talking about. To make this lemma unambigious, it should be written as: Lemma lookup_alter_None {A} (f : A → A) (m : M A) i j : alter f i m !! j = None↔ m !! j = None. That is, we have to specify the type of `m`.

Before, we often had to insert awkward casts when using them. Also, the generality of also having them on Type, is probably not useful.

For example, instead of: Notation "( X ⊆ )" We now use: Notation "( X ⊆)" We were already doing this for = and ≡. This solves some conflicts with the notations of MetaCoq.

We do this by introducing a type class UpClose with notation ↑. The reason for this change is as follows: since `nclose : namespace → coPset` is declared as a coercion, the notation `nclose N ⊆ E` was pretty printed as `N ⊆ E`. However, `N ⊆ E` could not be typechecked because type checking goes from left to right, and as such would look for an instance `SubsetEq namespace`, which causes the right hand side to be illtyped.
