- 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

Conflicts:
	Makefile.in
	configure.in

since it is not interpreted as infinite by CVC4

As a side effect, this puts symbolic links back inside the archive. They
had been lost since 0.82 and prevented the use of a local installation.

It is now done by a different mechanism than parsing of time:
timeregexp is not any more used for parsing of steps, stepsregexp is
used instead.

- Switch from AUFNIRA to AUFBVNIRA logic in cvc4_bare

This commit also removes the laziness for accessing symbols, since they
are already in the scope at the time the plugin is loaded.
