One more update to the pollset API before we start using it

in the httpd: add a "flags" argument to apr_pollset_create().

When we add support for OS-specific poll alternatives in the
future, I anticipate that we'll need to give apps a way to
pass hints to the pollset create function to help it pick
the best mechanism for a specific pollset.  (E.g., there may
be situations where we'll want to use poll(2) even if the OS
has /dev/poll.)  This "flags" argument is a placeholder to
make it possible to add such hints later.
