* [x/stake] \#2394 Split up UpdateValidator into distinct state transitions applied only in EndBlock
* Tendermint
* Update tendermint version from v0.23.0 to v0.25.0, notable changes
* Mempool now won't build too large blocks, or too computationally expensive blocks
* Maximum tx sizes and gas are now removed, and are implicitly the blocks maximums
* ABCI validators no longer send the pubkey. The pubkey is only sent in validator updates
* Validator set changes are now delayed by one block
* Block header now includes the next validator sets hash
* BFT time is implemented
* Secp256k1 signature format has changed
* There is now a threshold multisig format
* See the [tendermint changelog](https://github.com/tendermint/tendermint/blob/master/CHANGELOG.md) for other changes.

## CompleteUnbonding
Complete the unbonding and transfer the coins to the delegate. Realize any
slashing that occurred during the unbonding period.

unbondingQueue(currTime time.Time):

## CompleteRedelegation
Note that unlike CompleteUnbonding slashing of redelegating shares does not
take place during completion. Slashing on redelegated shares takes place
actively as a slashing occurs. The redelegation completion queue serves simply to
clean up state, as redelegations older than an unbonding period need not be kept,
as that is the max time that their old validator's evidence can be used to slash them.
