3c6da0ffdc Clause buffer must be fitered when popping 
Indeed imagine the following case:
"push; assume [c]; pop; push; solve"
since c has user-level 1, in the current state, it would
have been wrongfully added to the solver state when solve
is run.

9be4c66911 [bugfix] Clause level now computed at creation 
Apart from new assumptions, clause level can always
be computed from the histoy of the clause, so it is
better to do it in Solver_types when creating clauses.
Aditionally, it seems there was an error in the manual
computing of clause level somewhere, this fixes the bug.
