Predominantly following the discussions regarding the conventions of using mocks, I have decided to revert back to the previous state where mocks were specialized and stored in the separate packages that used them rather then have a generalized mock in the evidence package.
This also was a problem as the state package were running tests too slow and occasionally timing out unnecessarily.
For the replay file I renamed mockEvidencePool to emptyEvidencePool to illustrate that it was intentionally like this and not give the impression that testing software was being used in production

* rpc: use BlockStoreRPC instead of BlockStore
BlockStoreRPC is a limited version of BlockStore interface, which does
not include SaveBlock method.
Closes#4159
* remove BlockStoreRPC interface in favor of single BlockStore
interface

* Expose priv validators for use in testing
* Generalize block header validation test past height 1
* Remove ineffectual assignment
* Remove redundant SaveState call
* Reorder comment for clarity
* Use the block executor ApplyBlock function instead of implementing a stripped-down version of it
* Remove commented-out code
* Remove unnecessary test
The required tests already appear to be implemented (implicitly) through
the TestValidateBlockHeader test.
* Allow for catching of specific error types during TestValidateBlockCommit
* Make return error testable
* Clean up and add TestValidateBlockCommit code
* Fix formatting
* Extract function to create a new mock test app
* Update comment for clarity
* Fix comment
* Add skeleton code for evidence-related test
* Allow for addressing priv val by address
* Generalize test beyond a single validator
* Generalize TestValidateBlockEvidence past first height
* Reorder code to clearly separate tests and utility code
* Use a common constant for stop height for testing in state/validation_test.go
* Refactor errors to resemble existing conventions
* Fix formatting
* Extract common helper functions
Having the tests littered with helper functions makes them less easily
readable imho, so I've pulled them out into a separate file. This also
makes it easier to see what helper functions are available during
testing, so we minimize the chance of duplication when writing new
tests.
* Remove unused parameter
* Remove unused parameters
* Add field keys
* Remove unused height constant
* Fix typo
* Fix incorrect return error
* Add field keys
* Use separate package for tests
This refactors all of the state package's tests into a state_test
package, so as to keep any usage of the state package's internal methods
explicit.
Any internal methods/constants used by tests are now explicitly exported
in state/export_test.go
* Refactor: extract helper function to make, validate, execute and commit a block
* Rename state function to makeState
* Remove redundant constant for number of validators
* Refactor mock evidence registration into TestMain
* Remove extraneous nVals variable
* Replace function-level TODOs with file-level TODO and explanation
* Remove extraneous comment
* Fix linting issues brought up by GolangCI (pulled in from latest merge from develop)

Refs #2659
Breaking changes in the mempool package:
- Mempool now an interface
- old Mempool renamed to CListMempool
Breaking changes to state package:
- MockMempool moved to mempool/mock package and renamed to Mempool
- Mempool interface moved to mempool package
* assert CListMempool impl Mempool
* gofmt code
* rename MempoolReactor to Reactor
- combine everything into one interface
- rename TxInfo.PeerID to TxInfo.SenderID
- unexpose MempoolReactor.Mempool
* move mempool mock into top-level mock package
* add a fixme
TxsFront should not be a part of the Mempool interface
because it leaks implementation details. Instead, we need to come up
with general interface for querying the mempool so the MempoolReactor
can fetch and broadcast txs to peers.
* change node#Mempool to return interface
* save commit = new reactor arch
* Revert "save commit = new reactor arch"
This reverts commit 1bfceacd9d.
* require CListMempool in mempool.Reactor
* add two changelog entries
* fixes after my own review
* quote interfaces, structs and functions
* fixes after Ismail's review
* make node's mempool an interface
* make InitWAL/CloseWAL methods a part of Mempool interface
* fix merge conflicts
* make node's mempool an interface
Closes#1798
This is done by making every mempool tx maintain a list of peers who its received the tx from. Instead of using the 20byte peer ID, it instead uses a local map from peerID to uint16 counter, so every peer adds 2 bytes. (Word aligned to probably make it 8 bytes)
This also required resetting the callback function on every CheckTx. This likely has performance ramifications for instruction caching. The actual setting operation isn't costly with the removal of defers in this PR.
* Make the mempool not gossip txs back to peers its received it from
* Fix adversarial memleak
* Don't break interface
* Update changelog
* Forgot to add a mtx
* forgot a mutex
* Update mempool/reactor.go

* GetEvidence -> GetEvidenceInfo
* fix TestStoreCommitDuplicate
* comment in VerifyEvidence
* add check if evidence was already seen
- modify EventPool interface (EventStore is not known in ApplyBlock):
- add IsCommitted method to iface
- add test
* update changelog
* fix TestStoreMark:
- priority in evidence info gets reset to zero after evidence gets committed
* review comments: simplify EvidencePool.IsCommitted
- delete obsolete EvidenceStore.IsCommitted
* add simple test for IsCommitted
* update changelog: this is actually breaking (PR number still missing)
* fix TestStoreMark:
- priority in evidence info gets reset to zero after evidence gets
committed
* review suggestion: simplify return
This also refactors the prior mempool to filter to be known as
"precheck filter" and this new filter is called "postcheck filter"
This PR also fixes a bug where the precheck filter previously didn't
account for the amino overhead, which could a maliciously sized tx to
halt blocks from getting any txs in them.

* #1920 try to fix race condition on proposal height for published txs
- related to create_empty_blocks=false
- published height for accepted tx can be wrong (too low)
- use the actual mempool height + 1 for the proposal
- expose Height() on mempool
* #1920 add initial test for mempool.Height()
- not sure how to test the lock
- can the mutex reference be of type Locker?
-- this way, we can use a "mock" of the mutex to test triggering
* #1920 use the ConsensusState height in favor of mempool
- gets rid of indirections
- doesn't need any "+1" magic
* #1920 cosmetic
- if we use cs.Height, it's enough to evaluate right before propose
* #1920 cleanup TODO and non-needed code
* #1920 add changelog entry
if we call it after, we might receive a "fresh" transaction from
`broadcast_tx_sync` before old transactions (which were not
committed).
Refs #1091
```
Commit is called with a lock on the mempool, meaning no calls to CheckTx
can start. However, since CheckTx is called async in the mempool
connection, some CheckTx might have already "sailed", when the lock is
released in the mempool and Commit proceeds.
Then, that spurious CheckTx has not yet "begun" in the ABCI app (stuck
in transport?). Instead, ABCI app manages to start to process the
Commit. Next, the spurious, "sailed" CheckTx happens in the wrong place.
