LastCommitRound should always be >= 0 for heights > 1.
In State.updateToState, last precommit is computed only when round
greater than -1 and has votes. But "LastCommit" is always updated
regardless of the condition. If there's no last precommit, "LastCommit"
is set to (*types.VoteSet)(nil). That's why "LastCommit" can be -1 for
heights > 1.
To fix it, only update State.RoundState.LastCommit when there is last
precommit.
Fixes#2737

## Description
in consensus/state.go, when calulating metrics, retrieve address (ergo, pubkey) once prior to iterating over validatorset to ensure we do not make excessive calls to signer.
Partially closes: #4865
Closes#4603
Commands used (VIM):
```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```
where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.
creates a proof of lock change which is an array of votes that proves the validator was permitted to change locked block and vote again. This proof is stored in the evidence pool and is used as a part of amnesia evidence

- do not send any LastCommitInfo.Votes for 1st block.
- use cs.LastValidators (not cs.Validators) in recordMetrics when counting missing validators
note:
remember that the first LastCommit is intentionally empty, so it makes
sense for LastCommitInfo.Votes to also be empty. Because we can't really
tell if validator signed or not. Similar for ^ metrics, we can't say if
particular validator was missing or not.

* VoteSignBytes builds CanonicalVote
* CommitVotes implements VoteSetReader
- new CommitVotes struct holds both the Commit and the ValidatorSet and
implements VoteSetReader
- ToVote takes a ValidatorSet
* fix TestCommit
* use CommitSig.BlockID
Commits may include votes for a different BlockID, could be nil,
or different altogether. This means we can't use `commit.BlockID`
for reconstructing the sign bytes, since up to -1/3 of the commits
might be for independent BlockIDs. This means CommitSig will need to
include an indicator for what BlockID it signed - if it's not the
committed one or nil, it will need to include it fully in order to be
verified. This is unfortunate but unavoidable so long as we include
votes for non-committed BlockIDs (which we do to track validator
liveness)

* Remove deprecated PanicXXX functions from codebase
As per discussion over
[here](https://github.com/tendermint/tendermint/pull/3456#discussion_r278423492),
we need to remove these `PanicXXX` functions and eliminate our
dependence on them. In this PR, each and every `PanicXXX` function call
is replaced with a simple `panic` call.
* add a changelog entry
Refs #3262
This fixes two small bugs:
1) lite/dbprovider: return `ok` instead of true in parse* functions. It's weird that we're ignoring `ok` value before.
2) consensus/state: previously because of the shadowing we almost never output "Error with msg". Now we declare both `added` and `err` in the beginning of the function, so there's no shadowing.

As per #3043, this adds a ticker to sync the WAL every 2s while the WAL is running.
* Flush WAL every 2s
This adds a ticker that flushes the WAL every 2s while the WAL is
running. This is related to #3043.
* Fix spelling
* Increase timeout to 2mins for slower build environments
* Make WAL sync interval configurable
* Add TODO to replace testChan with more comprehensive testBus
* Remove extraneous debug statement
* Remove testChan in favour of using system time
As per
https://github.com/tendermint/tendermint/pull/3300#discussion_r255886586,
this removes the `testChan` WAL member and replaces the approach with a
system time-oriented one. In this new approach, we keep track of the
system time at which each flush and periodic flush successfully
occurred.
The naming of the various functions is also updated here to be more
consistent with "flushing" as opposed to "sync'ing".
* Update naming convention and ensure lock for timestamp update
* Add Flush method as part of WAL interface
Adds a `Flush` method as part of the WAL interface to enforce the idea
that we can manually trigger a WAL flush from outside of the WAL. This
is employed in the consensus state management to flush the WAL prior to
signing votes/proposals, as per https://github.com/tendermint/tendermint/issues/3043#issuecomment-453853630
* Update CHANGELOG_PENDING
* Remove mutex approach and replace with DI
The dependency injection approach to dealing with testing concerns could
allow similar effects to some kind of "testing bus"-based approach. This
commit introduces an example of this, where instead of relying on
(potentially fragile) timing of things between the code and the test, we
inject code into the function under test that can signal the test
through a channel.
This allows us to avoid the `time.Sleep()`-based approach previously
employed.

* Add broken test to illustrate WAL sync test problem
Removes test-related state (dependency injection code) from the WAL data
structure and adds test code to illustrate the problem with using
`WALGenerateNBlocks` and `wal.SearchForEndHeight` to test periodic
sync'ing.
* Fix test error messages
* Use WAL group buffer size to check for flush
A function is added to `libs/autofile/group.go#Group` in order to return
the size of the buffered data (i.e. data that has not yet been flushed
to disk). The test now checks that, prior to a `time.Sleep`, the group
buffer has data in it. After the `time.Sleep` (during which time the
periodic flush should have been called), the buffer should be empty.
* Remove config root dir removal from #3291
* Add godoc for NewWAL mentioning periodic sync
