Do a second pass on the treatment of user-given implicit arguments. Now

works in inductive type definitions and fixpoints. The semantics of
an implicit inductive parameter is maybe a bit weird: it is implicit in the
inductive definition of constructors and the contructor types but not in
the inductive type itself (ie. to model the fact that one rarely wants A
in vector A n to be implicit but in vnil yes). Example in test-suite/
Also, correct the handling of the implicit arguments across sections. 
Every definition which had no explicitely given implicit arguments was
treated as if we asked to do global automatic implicit arguments on
section closing. Hence some arguments were given implicit status for no
apparent reason.
Also correct and test the parsing rule which disambiguates between {wf
..} and {A ..}.
