core: Add Consensus to replace core.Blocklattice (#35)

* Make Sequencer return slice of blocks.

* Fix naming issue

The function 'getHeightVecto' would return ackingStatusVector.

* Fix comment error.

* Add methods to collect info when proposing blocks.

* Add test.App

* Add test.Gov

* Move this type to core.types to avoid cyclic import.

* Add core.Consensus

* Move getMedianTime, interpoTime to util

These functions are not depending on members of core.consensusTimestamp and
is required when testing core.Consensus.

* Make sure types.Block.Clone would copy critical fields.

* Remove core.blocklattice

* Define 'infinity' in core/total-ordering

This definition is defined in core/blocklattice originally.

* Fix a bug when processing the same block twice.

* Integrate simulation with core.Consensus

core.Consensus is a replacement of core.Blocklattice

* Fix the comment to use sigular form.

* Move lock mechanism to sub modules.

* phi should be 2*fmax+1

* Fixup: should aborting when the validator is added

* Fix for new block fields

* Fix the bug that the total ordering sequence is wrong.
