- change the syntax converter of z3 for bitvectors
  (z3 get confused if there is a variable "bv1" and then a declaration
  (_ bv1 32))

- fix bitvector/double_of_int, bitvector/power2 and queens test output

- add "map" to the smtv2 printer blacklist (from z3)
- change smtv2 driver so that errors (in particular z3's) are correctly reported

Message mentioned format string which is not allowed, also slightly more
precise (in fact %S is allowed in other places)

accept also camlp4 (not only camlp5) for coq plugin compilation
