I had to check this. InitStart does update state_ if it's equal CMD_COMPLETE_S so it's fine.

I am blindly trusting you here. I haven;t checked the index calculations but the tests are failing and it's a sign that there is a mistake somewhere around here 😄

This is needed in order to eliminate cases where we return INPUT_PENDING but do not consume the whole string by rejecting just several bytes. This should simplify buffer management for the caller, so that if they pass a string that did not result in complete parsed request, at least the whole string is consumed and can be discarded.

Also, eliminate cases where we return INPUT_PENDING but do not consume the whole string. This should simplify buffer management for the caller, so that if they pass a string that did not result in complete parsed request, at least the whole string is consumed and can be discarded.
This PR handles only the ParseLen function that now stashes all the partial data if not enough data is provided.
