Closes#2812
This PR adds the flag --for-zero-height to gaiad export, which runs several alterations to the application state to prepare for restarting a new chain in a consistent fashion.
It also:
* Moves Gaia's export code to cmd/gaia/app/export.go for cleaner separation.
* Fixes an inconsistency where we treated the initChainer as happening at height -1 - it should now happen at height 0, since the first header sent by Tendermint has height 1.
* Runs the runtime invariant checks on start (in initChainer)
* Adds a few auxiliary functions to clear slashing periods
* Removes the Height field from Delegation objects in x/stake, which was not used anywhere
* Update slashing import/export
* More slashing.WriteGenesis
* Add test import/export to CI
* Store equality comparison.
* Fix validator bond intra-tx counter
* Set timeslices for unbonding validators
* WriteGenesis => ExportGenesis
* Delete validators from unbonding queue when re-bonded
* Hook for validator deletion, fix staking genesis tests
* Start upgrade. Currently go test ./... hangs.
* (squash this) Fix staking tests
* wip
* note what changes need to be made to make this work on tm v0.23.0
* Fix addr -> pubkey map
* cleanup code
* Fix slashing test failures except for begin blocker
* fix all slashing tests
* fix lcd tests
* Address PR comments
* add link to changelog.
* (wip) start making addrToPubkey map persisted. Since amino can't handle maps,
we have to change from what this commit is doing.
* Use the correct method of storing a map
* (squash this) address PR comments
* Did you run 'make'?
* remove gaiadebug binary
