Resolves a URI against a base URI, conforming to RFC 3986, Section 5
Assumes new location is already copied to the beginning of
aux_buf.*. Parses that new location as a URI, and then resolves the path in place.If a merge needs to take place, the newly constructed path will be stored in
aux_buf.*just after the copied location, andaux_buf.*will be modified to only contain the remaining unused space.
