Title: [Routing] improve matching performance by using possesive quantifiers

BC break: NO

My benchmarks showed a performance improvement of 20% when matching routes that make use of possesive quantifiers because it prevents backtracking when it's not needed.

This is based on 5469 and will be rebased later.
