Use loop for acceptParams

[nigrosimone]

from expressjs/express#6066

Using a loop here would improve performance for parsing over splitting into an array and iterating over it, then splitting some more. If we prefer the overall split on ; for readability though, we can still avoid the second split by using indexOf instead. There's also some slices and trim that could be avoided for extra performance but it seemed a little overkill for this function.
