dyoung b3fc296326 Use malloc(9) for sockaddrs instead of pool(9), and remove dom_sa_pool
and dom_sa_len members from struct domain.  Pools of fixed-size
objects are too rigid for sockaddr_dls, whose size can vary over
a wide range.

Return sockaddr_dl to its "historical" size.  Now that I'm using
malloc(9) instead of pool(9) to allocate sockaddr_dl, I can create
a sockaddr_dl of any size in the kernel, so expanding sockaddr_dl
is useless.

Avoid using sizeof(struct sockaddr_dl) in the kernel.

Introduce sockaddr_dl_alloc() for allocating & initializing an
arbitrary sockaddr_dl on the heap.

Add an argument, the sockaddr length, to sockaddr_alloc(),
sockaddr_copy(), and sockaddr_dl_setaddr().

Constify: LLADDR() -> CLLADDR().

Where the kernel overwrites LLADDR(), use sockaddr_dl_setaddr(),
instead.  Used properly, sockaddr_dl_setaddr() will not overrun
the end of the sockaddr.
