* extract borrow sync logic into separate func
* fix borrow reward calculations
Use the normalized borrow as the source shares in reward calculations.
* extract supply sync logic into separate func
* prepare to fix supply reward calculations
* fix deposit reward calculations
Use the normalized deposit as the source shares in reward calculations.
* extract usdx sync logic into separate func
* prepare to fix usdx reward calculations
* fix cdp reward calculations
Use the normalized cdp debt as the source shares in reward calculations.
* fix compile error from messed up partial stage
* Fix incentive usdx reward bug (#976)
* minor test refactors
* fix overpayment bug
Init methods should not read params.
Add test to cover bug
* fix typos
* add test for validate multi reward periods
* tidy up: combine files
* don't accumulate global indexes containing zeros
Previously if the time since last block was 0,
indexes were added containing 0s.
Now leave them out. Missing is assumed to be 0.
* move state independent test to types folder
* clarify reward source concept to "source shares"
- rename variables and update doc comments
- extract method from swap accumulation
* tidy up and expand swap accumulation unit tests
* rename swap test file to match others
* update swap pool id format in tests
* refactor borrow accumulation, use new accumulator
* refactor supply accumulation, use new accumulator
* refactor delegator accumulation, use accumulator
* refactor usdx accumulation, use new accumulator
* fix types const
* remove unsed methods
* more usdx minting param validation.
Protect against the rewards per second denom changing.
It should always be "ukava".
* add safety check in InitGenesis
It prevents huge accumulations on the first block by limiting all
previous accumulation times to be within one year of genesis
* add todo for adding swp token distirbution info

needed by delegation rewards
* fix typo in test names
