Add "-q" argument to sysctl(8), which suppresses a limited set of
warnings/ errors generated. In particular, it suppresses "unknown oid"
when attempting to get or set a sysctl not present in the kernel.

% When bus_alloc_resource_any() fails, dc_detach() is called and it
% attempts to deallocate busdma tags and resources that haven't been
% allocated yet, causing a panic every time a dc interface fails to
% attach. Fix by checking that we really have something to dealloc
% before calling bus_dma*() functions.

In mountd_precmd(), use rc_args, not mountd_args to
override the value of mountd_args. This fixes the problem
where mountd_args was not properly being set if
weak_mountd_authentifcation="YES" was set in rc.conf.

Assert that (vp) is locked in fifo_close(), since we rely on the
exclusive vnode lock to synchronize the reference counts on struct
fifoinfo.

Re-comment sbcompress() to explain what it is it does; it took me
quite a bit of reading to figure it out, and I want to avoid figuring
it out again.
Convert an if (foo) else printf("this is almost a panic") into a
KASSERT.

The socket pointers in fifoinfo are not permitted to be NULL, so
don't check if they are, it just confuses the fifo code more.

Test the new M_VLANTAG packet flag before calling
m_tag_locate(). This adds little overhead of a simple
bitwise operation in case hardware VLAN acceleration
is on, yet saves the more expensive function call if
the acceleration is off.

Don't consider being unable to open the bounds file worthy of printing
at LOG_WARNING by default; instead, consider it something to be printed
to the tty when 'verbose' mode is set. This avoids printing out extra
lines at every boot on a system with crash dumps enabled, but that has
not yet had to generate a crashdump.

Use kenv -q to extract dumpdev rather than kenv, in order to avoid
spamming the console in the event that a loader tunable 'dumpdev'
isn't defined, which is not a relevant failure to report.

Push warning in net_add_domain() down under DIAGNOSTIC. At the moment, the
only loadable domain is netgraph and it has no problems to be loaded
at runtime, since it doesn't use if_afdata[AF_NETGRAPH], yet.

The bsdtar_warnc() reporting function requires the program name to be
set up before it is called, so move the progname initialization before
the first possible call to bsdtar_warnc().

Handle circular dependencies properly (via errx(3)) rather than dumping
core. This bug was made visible by a recent change to the audio/timidity++
