The types were failing to remove props they injected from requirements
for the parents rendering them. By using Omit we can omit props that are
injected from the connect component so that we don't get errors during
parent rendering.
All of this is done through type inference so that end users don't have
to be aware that this is happening.
* Fix first round of weak type errors
Done through griddle-react
* 95% done with weak type fixes
* Fix last couple of weak type errors
* Remove some lint from mithril tests
* mithril's Lifecycle is not a weak type any more
Restore the Lifecycle constraints in the rest of the definitions.
* Fix react-redux tests after #16652 broke them
* Remove package-lock.json
* Add overloads to account for `mergeProps`
This also provides better typings for users of `strictNullChecks`
* more overloads and tests
* accept `null | undefined`
* allow placeholder typings
* tests
* one `ComponentDecorator`
