* Generate correct hash/signature when generating blocks.
* Refine naming, types.
- type of chainNum should be uint32 by default
- rename blockCount to blockNum
- rename nodeCount to chainNum

core.blockPool is used to cache blocks arrived
out-of-order. Our consensus should retry
those blocks after their acking blocks added
to lattice.

blocklattice is used to replace reliable broadcast.
Aiming to fix these problems:
- The mechanism related to strong ack is no
longer required.
- The sanity-check of one block would be passed
even if its acking block doesn't exist.
This commit doesn't include logic to handle
out-of-order blocks. It should be done in
another PR.

* 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.

Add a new Governance interface for interaction with the governance contract.
Also remove the ValidateBlock call in application interface as the application should validate it before putting it into the consensus module.
A new BlockConverter interface is also added. The consensus module should accept the BlockConverter interface in future implementation, and use the Block() function to get the underlying block info.

- Allow to dump blockdb to a json file
- Compared to leveldb, a json file is easier to trace.
- Add interfaces block database:
- Close would be required by database that needs cleanup.
- BlockIterator is required when we need to access 'all' blocks,
adding a new method 'GetAll' as the constructor for iterators.
- Remove GetByValidatorAndHeight from blockdb.Reader
- This function is not used anywhere, to make interface
minimum, remove it.
- Fix typo: backend -> backed

* Refactor and add acking module
Extract acking module for unit testing. This commit splits functions
into small pieces for better understanding and easy unit testing.

Outputs of total ordering are sorted by hash value in blocklattice.go,
but was checked orderly in test, which the order might change due to
random hash.
Added common.Hashes.

* core: refactor acking relationship
Use AckBy only, and remove IndirectAcks.
Also fix the issue where validator is not filling Height when proposing
block.
