NextConsensus API is not used by the users of dBFT. NextConsensus handling (proposal, verification and agrreement) is moved to the upper level of dBFT users. Starting from this commit NextConsensus verification should be performed by dBFT user manually in WithVerifyPrepareRequest callback. A part of #84. Signed-off-by: Anna Shaleva <[email protected]>

Version context field is always set to 0. There is no API to change Version in dBFT context. Given a possibility of Block version change, we either need to introduce this Version initializer or need to move Version handling out of dBFT. The latter case is chosen, because in this case block/PrepareRequest version can be handled directly by node depending on block index fetched from dBFT context. Also remove Version() block API, it's unused. A part of #84. Signed-off-by: Anna Shaleva <[email protected]>
It's unused by dBFT, and thus, it's not needed in this interface. If this property is used by dBFT user, then the user need to convert dBFT Block to user's Block and retrieve all necessary info. A part of #84. Signed-off-by: Anna Shaleva <[email protected]>
All dBFT payloads implementations should be kept in the same package or have exported fields. It's inevitable since dBFT user have to refer to payload fields via converting dBFT interfaces to user-defined local structures. dBFT test (`dbft_test` package) imports custom payloads implementations from `internal`. Since all payloads will be moved to the same package, we need to split this package from `main` package of simulation. A consequence of #84. Signed-off-by: Anna Shaleva <[email protected]>
It's needed to be able to cast dBFT payload interfaces to local user-defined payloads implementations during consensus service functioning. A psrt of #84. Signed-off-by: Anna Shaleva <[email protected]>
It's unused by dBFT and thus, should be removed from Block interface. If user need to access this data, then he should convert dbft.Block to the local user-defined Block implementation. A part of #84. Signed-off-by: Anna Shaleva <[email protected]>
This API is unused by dBFT. If a user needs to access ChangeView timestamp, he has to convert dbft.ChangeView to the user-defined ChangeView implementation. A part of #84. Signed-off-by: Anna Shaleva <[email protected]>

Store Timer interface along with other dBFT interfaces and provide default timer implementation in `timer` package. Create `dbft.HV` interface and configuration for its customisation. Provide default implementation of `dbft.HV` in `timer` package. A part of #84. Signed-off-by: Anna Shaleva <[email protected]>
Also add a record to CHANGELOG.md. A part of #84. Signed-off-by: Anna Shaleva <[email protected]>

This PR removes exported APIs from interfaces declared in the dbft package. Those APIs are remove that are not used by dBFT. If dBFT user wants to access some of removed dbft payloads APIs, then it should cast dbft payload interface to the corresponding locally-defined payload implementation.
Regarding to the rest of APIs, @roman-khimov, need your opinion:
Timerrelated Config API is currently unused in both NeoGo and Bane (WithTimer,WithTimestampIncrement). Default timer implementation is used, thus, timer API may be removed (exceptWithSecondsPerBlock). However, in general it's nice to have the ability to customize timer. What is the desired behaviour? (I vote to keep it).VerifyPrepareResponseis currently unused by NeoGo and Bane, no verification is being performed, but it may be useful for future Bane consensus, thus I'd suggest to keep it.Close #84.
