Change the way primitive projections are declared to the kernel.
Now kernel/indtypes builds the corresponding terms (has to be trusted)
while translate_constant just binds a constant name to the
already entered projection body, avoiding the dubious "check"
of user given terms. "case" Pattern-matching on primitive records is
now disallowed, and the default scheme is implemented using
projections and eta (all elimination tactics now use projections
as well). Elaborate "let (x, y) := p in t" using let bindings
for the projections of p too.
