- panic("soaccept: !NOFDREF")
- fatal trap 12, with tracebacks going thru soclose and soaccept
can be hung.
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.

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.
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.
This takes the conditionals out of the code that has been tested by
various people for a while.
ps and friends (libkvm) will need a recompile as some proc structure
changes are made.

This sysctl is used by the diskless startup code and new rc.conf. If
it cannot be found or is empty, the system should revert to using /etc.
where select(2) can return that a listening socket has a connected socket
queued, the connection is broken, and the user calls accept(2), which then
blocks because there are no connections queued.

on other types of files. It has been broken since the Lite2 merge

patch. lf can't be dereferenced after the unload attempt, in case it
was freed. Instead, decrement first and back it out if the unload failed.
This should be relatively immune to races caused by the user since the
userref count will be zero for the duration of the actual unloading and
will stop further kldunload attempts.

throwing away the buffer contents will often result in filesystem
corruption and this solution will at least correctly deal with transient

Also, a number of cases where manually inserted code has been removed
and replaced with an inline function call giving us better functional
isolation in the source.

forced commits. This commit is somewhat rough in regards to code
cleanup issues.
