Clock ticks are considered as the sources of non-deterministic data for
virtual machine. This patch implements saving the clock values when they
are acquired (virtual, host clock, rdtsc, and some other timers).
When replaying the execution corresponding values are read from log and
transfered to th
This patch introduces command line options for enabling recording or replaying
virtual machine behavior. "-record" option starts recording of the execution
and saves it into the log, specified with "fname" parameter. "-replay" option
is intended for replaying previously saved log.

freeing the resources when simulator closes.
