z3_smtv2* .drv : factorized

In the Gappa printer, perform a pseudo-congruence on the goal and move the introduce_premises transformation after abstraction.

Goal
  h (f x) = 1 /\ f x = g y -> h (g y) = 1
is now transformed by fmla_cond_subst into
  h (g y) = 1 /\ f x = g y -> h (g y) = 1
which can now be abstracted to
  abstr = 1 /\ abstr1 = abstr2 -> abstr = 1.

This makes bench/valid/intreal.why pass with Gappa.

This fixes the following assertion failure:
anomaly: File "src/printer/gappa.ml", line 182, characters 19-25: Assertion failed

TPTP/simplify : explicit not anymore the default

Currently only in the driver z3_array.drv

whycpulimit : Fix return the status of the prover
gappa       : Fix inversion (should use meta showing
              what musn't be instantiated)

sorry for forgetting to add cpulimit_time.c no it is useless

"%h:%m:%s:%i" (i for mIlliseconds)

Spass does'nt give cputime but wallclock.
eprover doesn't always give time. so use cpulimit_time for them.

add %b for the memlimit in bytes

encoding_sort   : identity on meta lsymbol without definition
                  undefined symbol are defined before using them...

courses  WP_registerStudent : 0.53 s -> 0.03!!

from the prover output the time used by the prover.

An intermediate format "h:m:s" is used to accept more output
than only seconds.

Add "eliminate_definition" before "eliminate_algebraic" in gappa.drv
"eliminate_recursion" or "eliminate_definition" should be always
applied before "eliminate_algebraic".
