Subject: expose variables for number of global events per simulated second,
 millisecond, microsecond, etc. so that the user can explicitly convert
 between system ticks and time and know what sorts of expensive operations are
 being used for that conversion.

dev/ns_gige.cc:
dev/sinic.cc:
dev/tsunami_io.cc:
dev/uart.cc:
sim/stat_control.cc:
sim/syscall_emul.hh:
    Use the new variables for getting the event clock
dev/etherdump.hh:
    delete variables that are no longer needed.
