Fix/clones

[ichorid]

This removes almost all the clones, changes NodeId to size, etc.
As the result, performance improves 4-8 times, and memory usage is reduced 2+ size.

Note that OUT4-based test ("long") was found to be broken: the original input file misplaced some values sometimes.
However, OUT3 (short) test passes now correctly.

smoke_perf_with_zero test still failing.

I increased success margin for smoke_perf_with_zero test to 80 seconds for now.

smoke_perf_with_zero test still failing.

if fails with a timeout if building with ASSERT enabled. If you disable ASSERT, the test completes in under 5 seconds. We should make smoke_perf_with_zero run with ASSERT = false. This will require either recompiling, or slightly changing the code to be able to turn ASSERT on and off during the runtime.
