* core: Use a channel to process ba confirmed block
* change the implementation of done() to react faster
* Fix restart
* Wait tipRound to change
* fix corner case
* Check for context

* Dropped block should not be added to db
- Here "dropped" means a block is older than
current tip of that chain.
* "Acking blocks doesn't exist" should be treated
as an error when adding a block

- when confirmed blocks passed to core.Consensus
aren't continuous in position in some chain, the
pulling would skip those missing blocks.
- fix: when some block is missing, avoid adding it
and all blocks after it to core.Consensus.
- we need to avoid the receive channel of network
module full.
- fix: during switching to core.Consensus, we
need to launch a dummy receiver to receive
from receive channel of network module.
- fix: between the period during core.Consensus
created and before running, a dummy receiver is
also required to receive from receive channel of
network module.

* Fix bug: the block pool is not resized.
* Fix forward acking.
* Fix panic when total ordering
* Fix total ordering flush hang
The blocks arrived first might be not delivered before other block.
Therefore, if some last block of previous round arrived before last
blocks in other chains, and are not delivered when entering flush mode.
Their corresponding flush-ready flag won't be turned on.
* Fix bug in core.latticeData
Invalid chainID is not thrown when preparing blocks.

* remove sanity check when adding blocks.
* call VerifyBlock after lattice's sanity check.
* remove checkRelation flag.

* Block proposing based on timestamp, instead of
count of blocks generated.
* Add method to find tips of each round in blockdb.
* Block proposing based on tips of last round found
on blockdb.

* Add test for num of chains changes.
* Return error in latticeData.prepareBlock
* Compare two positions
* Modify chainStatus from height-based to index-based.
* Fix consensus to use round variable
* Remove sanity check in chainStatus
* Fixup: refine sanity check
- verify if round switching is required or not by
chainTip's config.
- make the logic in sanity check more clear
- pospone acking relationship checking, they
are more expensive to check.

* Make sure block pool is large enough
It's safe to use a larger blockPool when
the number of chains is smaller.
* Construct latticeData via config.
* Seek acked blocks in blockdb when
unable to find them in memory cache.
In previous implementation, we assume
our cache in memory is enough to perform
DAG's sanity check. However, it's no longer
true when the number of chains might be
changed between rounds.
* Simplify purge.
Remove the relation to purge block by chainStatus.
