* all the provers with the same prover_id are threated as one prover,
* the first description of a prover in the file pdd.conf which have an
  executable with a good version is used,
* the order used to test the executable (exec) inside a prover description
  is not specified,
* a version_bad allows to forbid a version.
* a version_ok matches no warning is printed
* a version_old matches a warning is printed
* if no version matches a warning is printed

rebuild provers-data-conf when necessary; support for Gappa 0.14.0 (but Gappa's driver still to be fixed)

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

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.
