@NicoK , thanks for your reviews!
This PR mainly covers four processes related with credit-based feature in
`RemoteInputChannel`. I think it is better to split this PR into several small
ones, so we can focus on every process for easy review. Or what do you think?
I will rebase this PR one the latest change of first PR and submit the
updates today.---
