blockchain: add v2 reactor (#4361 )

The work includes the reactor which ties together all the seperate routines involved in the design of the blockchain v2 refactor. This PR replaces #4067 which got far too large and messy after a failed attempt to rebase.

## Commits:

* Blockchainv 2 reactor:

	+ I cleaner copy of the work done in #4067 which fell too far behind and was a nightmare to rebase.
	+ The work includes the reactor which ties together all the seperate routines involved in the design of the blockchain v2 refactor.

* fixes after merge

* reorder iIO interface methodset

* change iO -> IO

* panic before send nil block

* rename switchToConsensus -> trySwitchToConsensus

* rename tdState -> tmState

* Update blockchain/v2/reactor.go

Blockchain v2 Scheduler (#4043 )

* Add processor prototype

* Change processor API

    + expose a simple `handle` function which mutates internal state

* schedule event handling

* rename schedule -> scheduler

* fill in handle function

* processor tests

* fix gofmt and ohter golangci issues

* scopelint var on range scope

* add check for short block received

* small test reorg

* ci fix changes

* go.mod revert

* some cleanup and review comments

* scheduler fixes and unit tests, also small processor changes.

changed scPeerPruned to include a list of pruned peers

touchPeer to check peer state and remove the blocks from blockStates if the peer removal causes the max peer height to be lower.

remove the block at sc.initHeight

changed peersInactiveSince, peersSlowerThan, getPeersAtHeight check peer state

prunablePeers to return a sorted list of peers

lastRate in markReceived() attempted to divide by 0, temp fix.

fixed allBlocksProcessed conditions

maxHeight() and minHeight() to return sc.initHeight if no ready peers present

make selectPeer() deterministic.

added handleBlockProcessError()

added termination cond. (sc.allBlocksProcessed()) to handleTryPrunePeer() and others.

changed pcBlockVerificationFailure to include peer of H+2 block along with the one for H+1

changed the processor to call purgePeer on block verification failure.

fixed processor tests

added scheduler tests.

* typo and ci fixes

* remove height from scBlockRequest, golangci fixes

* limit on blockState map, updated tests

* remove unused

* separate test for maxHeight(), used for sched. validation

* use Math.Min

* fix golangci

* Document the semantics of blockStates in the scheduler

* better docs

* distinguish between unknown and invalid blockstate

* Standardize peer filtering methods

* feedback

* s/getPeersAtHeight/getPeersAtHeightOrAbove

* small notes

* Update blockchain/v2/scheduler.go

* Update comments based on feedback

* Add enum offset

* panic on nil block in processor

* remove unused max height calculation

* format shorter line
