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 allows for more control over `Hint Mode`.

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`.

Rename:  prefix_of > prefix and suffix_of > suffix because that saves keystrokes in lemma names. However, keep the infix notations with l1 `prefix_of` l2 and l1 `suffix_of` l2 because those are easier to read.  change the notation l1 `sublist` l2 into l1 `sublist_of` l2 to be consistent.  rename contains > submseteq and use the notation ⊆+

This patch was created using find name *.v  xargs L 1 awk i inplace '{from = 0} /^From/{ from = 1; ever_from = 1} { if (from == 0 && seen == 0 && ever_from == 1) { print "Set Default Proof Using \"Type*\"."; seen = 1 } }1 ' and some minor manual editing

Using this new definition we can express being contractive using a Proper. This has the following advantages:  It makes it easier to state that a function with multiple arguments is contractive (in all or some arguments).  A solve_contractive tactic can be implemented by extending the solve_proper tactic.
