When processing swapon -a (or swapctl -A, or swapctl -U) ignore lines in
...
fstab that have nothing to do with swapping (fs_type is neither "sw" nor "dp")
before running getfsspecname() on the fs_spec field of the line.
This avoids entries like this:
NAME=OFTEN_UNCONNECTED /local/archived ffs rw,log,noauto 0 0
in fstab from generating spurious error messages when the wedge named
is not currently connected to the system - that is the drive on which the
wedge exists is not connected, or not powered on. "noauto" handles that
for some other uses, the "0"s in fs_freq and fs_passno work for other uses,
but swap{on,ctl} never look at those fields (not for this purpose).
Non "sw"/"dp" lines were being ignored anyway, but not until (a little) later.

don't stop processing /etc/fstab when one entry fails, both for

add and remove loops. now when you add a new swap file and run
"swapctl -A" it won't give up after the existing one gives EBUSY
and move on to the rest.

Make the exit status from "swapctl -A" and "swapctl -U" tri-state:
...
0 for success; 1 for error; and 2 when no devices of the appropriate type
are defined in fstab(5). Previously, "no apropriate devices" was
indistinguishable from "error".

As discussed on tech-userlevel: enhance the -A/-U commands to take a -t
...
auto flag, which queries all local harddisks for swap partitions/
wedges and adds/removes them as swap device, a -f option to use the
first found swap device as dump device, and a -o option to only
auto-configure the dump device, but leave swap alone.
Add a -n option to make swapctl only say what it would do, but not
change any system state.
