Subject: Removing the special status of generic arguments defined by Coq
 itself.

This makes the TACTIC EXTEND macro insensitive to Coq-defined arguments. They
now have to be reachable in the ML code. Note that this has some consequences,
as the previous macro was potentially mixing grammar entries and arguments as
long as their name was the same. Now, each genarg comes with its grammar
instead, so there is no way to abuse the macro.
