Well this was thought provoking.

Drive out the use of malloc in two places.

In listen.c, using the global process pool instead.  That changes the
API into listen so that a process is passed in rather than the config
pool.  That's all was easy.

The pain is propogating a change into all N of the mpm, they
are all similar but different in their use of listen.c  There
is a lot to dislike about similar but code scattered code.

I changed the N setup_listener routines, they now take only
the server since they can dig the config and global pool
out of there.

Free today: ap_setup_prelinked_modules now takes the process so it
can allocate it's table in the process's pool rathern than use
malloc.
