Add a tunable delay at the beginning of the SHUTDOWN_FINAL at_shutdown
queue, allowing time to settle before we launch into the list of things
that are expected to turn the system off.
Fix a bug in at_shutdown_pri() where the second insertion always put
the item in second position in the queue.

Change microseq offsets. Previously, offsets of the program counter where
added to the index of the current microinstruction. Make them rely on the
index of the next executed microinstruction.

Using suser() means that the p_acflag will (can) be set, to show that
a process used super-powers during execution. It also makes it easier
to restrict roots we don't trust later on.

v_caddr_t with extreme prejudice. Here the bogons were originally
the same as for c_caddr_t (half-baked K&R support), but rev.1.95
changed one wrong cast and one harmless cast to 2 wrong casts,
and rev.1.96 only fixed the originally wrong cast.

measly 7193 new warnings for LINT, mostly for "unused parameter" and
"comparison between signed and unsigned".
terminating c_caddr_t with extreme prejudice. Here we depended
on the "opaque" type c_caddr_t being precisely `const char *'
to do unportable pointer arithmetic.
c_caddr_t with extreme prejudice. Here the original casts to
caddr_t were to support K&R compilers (or missing prototypes),
but the relevant source files require an ANSI compiler.
problem and solution is outlined in the comments, but basically
we needed a way to allow the SYSINIT mechanism to handle const void *
arguments and function pointers as well as non-const arguments and
function pointers while still maintaining the compiler's ability to
issue warnings if you try to use a bad combination.
c_caddr_t with extreme prejudice. Here the point of the original
cast to caddr_t was to break the warning about the const mismatch
between write(2)'s `const void *buf' and `struct uio's `char
*iov_base' (previous bitrot gave a gratuitous dependency on caddr_t
being char *). Compiling with -Wcast-qual made the cast a full
no-op.
This change has no effect on the warning for discarding `const'
on assignment to iov_base. The warning should not be fixed by
splitting `struct iovec' into a non-const version for read()
and a const version for write(), since correct const poisoning
would affect all pointers to i/o addresses. Const'ness should
probably be forgotten by not declaring it in syscalls.master.
c_caddr_t with extreme prejudice. Here we want to convert from
`const char *' to `const char *'. Casting through c_caddr_t is
not the way to do this. The original cast to caddr_t was apparently
to break warnings about const mismatches in other versions of BSD
(in 4.4BSDLite2, the conversion is from `const char *path' to
plain caddr_t).
Add C_DECLARE_MODULE - same as DECLARE_MODULE but uses C_SYSINIT
instead of SYSINIT.
The C_ items are going to be used for items passing const data to
sysinit.
