[pulseaudio-discuss] [PATCH] filter-apply: Mark modules as being autoloaded

(Based on Colin's review) We mark modules as being autoloaded so that
they can handle this as a special case if needed (which is required by
module-echo-cancel for now). This inverts how things were done and makes
using these modules manually less error-prone.
