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

* 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

* 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

* ci fix changes
* go.mod revert
+ use `trySend` the replicate peer sending
+ expose `next()` as a chan of events as output
+ expose `final()` as a chan of error, for the final error
+ add `ready()` as chan struct when routine is ready
+ ensure that we stop accepting messages once `stop` has been called
to avoid the case in which we attempt to write to a channel which
has already been closed
+ `routine.send` returns false when routine is not running
+ this will prevent panics sending to channels which have been
closed
+ Make output channels routine specific removing the risk of someone
writting to a channel which was closed by another touine.
+ consistency changes between the routines and the demuxer
* Add Schedule:
+ The schedule is a data structure used to determine the optimal
schedule of requests to the optimal set of peers in order to perform
fast-sync as fast and efficiently as possible.
* Add some doc strings
* fix golangci
