Base time API upon std::chrono

This should not change the behaviour of KLEE and mimics the old API.

- functions moved from util into time namespace
- uses time points and time spans instead of double
- CLI arguments now have the form "3h5min8us"

Changed command line parameters:
- batch-time (double to string)
- istats-write-interval (double to string)
- max-instruction-time (double to string)
- max-solver-time (double to string)
- max-time (double to string)
- min-query-time-to-log (double to string)
- seed-time (double to string)
- stats-write-interval (double to string)
- uncovered-update-interval (double to string)
- added: log-timed-out-queries (replaces negative max-solver-time)
