to use 0xffffffff (INADDR_NONE) as a netmask value. The fix
is to use inet_addr(3) which doesn't suffer from this problem.
PR: bin/28873
Also, while here, fixed the bug when netmask value was ignored
(RTF_HOST flag was set) if the "destination gateway netmask"
syntax is used, e.g. ``route add 1.2.3.4 127.1 255.255.255.255''.
The original code was certainly broken; it knows that whereto is
to be used for a sockaddr_in, so it should be declared as such.
To support multiple protocols, there is also a sockaddr_storage
struct that can be used; I don't think struct sockaddr is supposed
to be used anywhere other than for casts and pointers.

This one is strange and goes against my rusty compiler knowledge.
The global declaration
struct sockaddr whereto;
produces for both i386 && alpha:
.comm whereto,16,1
which means common storage, byte aligned. Ahem. I though structs
were supposed to be ALDOUBLE always? I mean, w/o pragma packed?
Later on, this address is coerced to:
to = (struct sockaddr_in *)&whereto;
Up until now, we've been fine on alpha because the address
just ended up aligned to a 4 byte boundary. Lately, though,
it end up as:
0000000120027b0f B whereto
And, tra la, you get unaligned access faults. The solution I picked, in
lieu of understanding what the compiler was doing, is to put whereto
as a union of a sockaddr and sockaddr_in. That's more formally correct
if somewhat awkward looking.
prematurely terminate the search for a usable disk. ENOENT is quite
normal in particulare now with the advent of devfs.
While being here, also remove /dev/wd0 and /dev/od0 from the list of
disks to search since we don't have them anymore.

backslash as nothing, treat it like a space so that adjacent lines
aren't glued together.

user runs with privilege, allowing the sending of icmp packets with
larger size (up to 48k, the default receive buffer size in ping),
which is useful for network driver development testing, as well
as experimentation with fragmentation.
