Syntax changes in typeclasses, remove "?" for usual implicit arguments
binding, add "!" syntax for the new binders which require parameters and
not superclasses. Change backquotes for curly braces for user-given
implicit arguments, following tradition. This requires a hack a la
lpar-id-coloneq. Change ident to global for typeclass names in class
binders. Also requires a similar hack to distinguish between [ C t1 tn ]
and [ c : C t1 tn ]. Update affected theories.
While hacking the parsing of { wf }, factorized the two versions of fix
annotation parsing that were present in g_constr and g_vernac.
Add the possibility of the user optionaly giving the priority for resolve and
exact hints (used by type classes). Syntax not fixed yet: a natural
after the list of lemmas in "Hint Resolve" syntax, a natural after a "|"
after the instance constraint in Instance declarations (ex in
Morphisms.v).
