This change moves the reflective setAccessible() calls on the request component
methods (needed so that they can be invoked reflectively from RequestHandler)
to within Router itself, eliminating the need to manually call this from each
Servlet class and then pass in the resulting Method objects. Instead, we just
pass in the request component class and let Router do the rest.
Old comments say that cross-package reflection is not allowed on AppEngine, but
while it's quite possible this was once the case, I can't reproduce that
limitation, and the documentation seems to contradict any such restriction:
"""
An application is allowed full, unrestricted, reflective access to its own
classes. It can query any private members, call the method
java.lang.reflect.AccessibleObject.setAccessible(), and read/set private
members.
"""
