Avoid several race conditions, especially when a transaction ends in error.
...
Guard sw_reg_start() against synchronous completions of the device
strategy routines, avoiding possibly boundless recursion.

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>.

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().

Keep a private pool of auxiliary resources (vndxfer & vndbuf structures)

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).

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.

add sequential swap device support, supplied by hibler many moons ago.

(Note that it needs config support, too, which isn't there yet, but
might be soon...) Also, general cleanup. use NODEV to terminate swdevt,
so that sparc port (and future) is happy.
