fc5dafc79b Fix a rather annoying problem where the sockaddr_dl which holds 
the link level name for the interface (ifp->if_sadl) is allocated
before ifp->if_addrlen is initialized, which could lead to allocating
too little space for the link level address.

Do this by splitting allocation of the link level name out of
if_attach() and into if_alloc_sadl(), which is normally called
by functions like ether_ifattach().  Network interfaces which
don't have a link-specific attach routine must call if_alloc_sadl()
themselves (example: gif).

Link level names are freed by if_free_sadl(), which can be called
from e.g. ether_ifdetach().  Drivers never need call if_free_sadl()
themselves as if_detach() will do it if it is not already done.

While here, add the ability to pass an AF_LINK address to
SIOCSIFADDR in ether_ioctl() (this is what caused me to notice
the problem that the above fixes).

acd96e1307 Don't use splimp() to block both net and tty interrupts. Instead, 
block both interrupt levels as appropriate.

efed547b78 Once we have a complete frame, schedule a SLIP software interrupt, 
and manipulate ipintrq from there.  This will allow us to clean up
the use of splimp() in this file later.

4edabe2501 Changed struct ifnet to have a pointer to the softc of the underlying 
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.
