      core: always allocate filters (ap_filter_t) on f->c->pool. · b156c592
      Yann Ylavic authored 
      When filters are allocated on f->r->pool, they may be destroyed any time
underneath themselves which makes it hard for them to be passed the EOR and
forward it (*f can't be dereferenced anymore when the EOR is destroyed, thus
before request filters return).

On the util_filter side, it also makes it impossible to flush pending request
filters when they have set aside the EOR, since f->bb can't be accessed after
it's passed to the f->next.

So we always use f->c->pool to allocate filters and pending brigades, and to
avoid leaks with keepalive requests (long living connections handling multiple
requests), filters and brigades are recycled with a cleanup on f->r->pool.

Recycling is done (generically) with a spare data ring (void pointers), and a
filter(s) context struct is associated with the conn_rec to maintain the rings
by connection, that is:

    struct ap_filter_conn_ctx {
        struct ap_filter_ring *pending_input_filters;
        struct ap_filter_ring *pending_output_filters;

        struct ap_filter_spare_ring *spare_containers,
                                    *spare_brigades,
                                    *spare_filters,
                                    *spare_flushes;
        int flushing;
    };

MMN major bumped (again).

      util_filter: split pending filters ring in two: input and output ones. · 3c6c689c
      Yann Ylavic authored 
      Pending input and output are now maintained separately in respectively
c->pending_input_filters and c->pending_output_filters, which improves
both performances and debug-ability.

Also, struct ap_filter_ring is made opaque, it's only used by util_filter
and this will allow us to later change it e.g. to a dual ring+apr_hash to
avoid quadratic search in ap_filter_prepare_brigade().

MMN major bumped due to the change in conn_rec (this is trunk only code
anyway for now).
