Make ptab in struct s_module embedded not a pointer.

This blows up bss (static) memory nearly twice but we'll get that
back and lots more once we slim down struct s_port in the next
commit.

Slim down struct s_port.

struct s_port contains filter array and couple of other fields that are
used only for newcamd and nothing else. They waste more than 2k in common
case.

To stop losing this much space, create private structure only for
newcamd fields and allocate it dynamically. This lowers struct s_port
size a lot and of course struct s_ptab even more because it contains
array of struct s_ports's.
