b5f69ff667 add a `char se_path[PATH_MAX]' member to struct swapent, that
the pathname of the swap device is saved into.  add a char *swd_path
member to struct swapdev, that contains a copy of the pathname
(using malloc(9)).  rename swapctl(2)'s SWAP_STATS to SWAP_OSTATS,
and add a new SWAP_STATS command (number).  make swapctl(SWAP_STATS,
...) [new version] copy the path out.  if COMPAT_13, also include
support for SWAP_OSTATS.  also fix a minor bug in swapctl(2).

the point of this is that swapfiles are now shown in `swapctl -l'.

97d2a58201 Fix slight argument bogosity with getgroups(), setgroups(), select(),
and swapctl().  For the former three, they use an 'int' in their user-land
prototype which was a 'u_int' in the kernel, which screwed up automatic
generation/checking of lint syscall stubs.  For the latter, the user-land
prototype uses a "const char *", but the syscall just used "char *".

From Chris Demetriou <cgd@pa.dec.com>.

d24dbbbfc4 A `simplelock' suffices for most swap device list traversals, as noted
by Chuck Cranor.

Use an exclusive (long-term) lock before applying changes to the swap
lists. This lock is also used by the stats system call because of possible
blocking in copyout().

55c881fbd2 when creating the per-device extent, use from 0 to nblks, and then
extent_alloc_region() any skipped space.  this is (basically) what
the previous swap code did (with rmaps rather than extents).

c61704d37c Remove the code that sets dumpdev, for two reasons:
- It was incorrect.  A dev_t should _never_ be compared against
  NULL, as 0 is a valid value (major 0, minor 0).
- The operator mave have _intentionally_ set dumpdev to "none"
  (i.e. NODEV), and setting it the first time a VBLK swap device
  is added would break the semantics.
setroot() deals with all dump device selection.  Dumps and swap are now
in no way related.
