Using multiple lists of implicit arguments in Program for preserving

the compatibility with the rest of the theories. Used multiple lists
of implicit arguments in Init only when the maximality status is not
modified in Program (and thus the compatibility is strictly
preserved). This improves the compatibility for the implicit arguments
of eq_refl and JMeq_refl between 8.2 and 8.3 when using Program (up to
the residual differences in the maximality status). For the constants
Acc_inv, inl, inr, left, right, Vnil, Vcons, the compatibility with
8.2 is not improved but the consistency between Program and the rest
of the library is.
