Consistently use if_printf() only in interface methods: if_start, if_ioctl, if_watchdog, etc or in functions that are used by these methods only.  In all other cases, device_printf should be used.

This also fixes several panics when if_printf() is called before softc->ifp was initialized.

As discussed on freebsd-threads@freebsd.org, a libpthread bug exists that this patch by Peter Edwards Corrects.

Here is a summary:

I've a problem when a process uses:
       libpthread
       detached threads
       mixed bound/unbound threads
       suspended threads  (a la pthread_resume_np())

whereby some newly created suspended threads don't get scheduled.
I think I've tracked it down, so if someone could review the
reasoning, I'd be grateful.

Newly launched threads have a "struct pthread" that may be allocated
from a freelist of GCed threads. Apparently, when detached threads
enter the GCed list, they can still have the "active" flag set on
them. Later, this causes problems when this thread is recycled and
resumed, because _thr_setrunnable_unlocked() doesn't add it to a
run queue.

thr_cleanup can be called either from the bound-threads scheduler,
or the unbound scheduler. One callsite clears "active", "needswitchout",
and "lock_switch" to zero before the call. The other callsite just
clears "check_pending". I think these flags are all either bound-thread
or unbound-thread specific, and that there was an unintended
assumption that the thread would remain with the same "boundedness"
after being recycled, which isn't neccessarily the case. (Or another
way - the idea was that there was no need to clear the "active"
flag on a bound thread, as its only used for unbound threads, but
a GCed bound thread might be recycled into an unbound thread)

Given that, it seems correct to clean up the thread the same way
for both cases, and just move that code into thr_cleanup.

Minor cleanup

Minor cleanups to sync.  $MidnightBSD$

Cleaned up source so that it would be more portable and inline with NetBSD.

The original patch falsely assumed time_t.

Check that -w width is not above maximum.  Use DWIDTH constant instead of a hard coded constant.

Bandaid to get world to build.  Need to research/fix this problem.

Sync with FreeBSD Stable/vendor.

update documentation as we've already imported the functional changes for 9.3.2p1.

Only catch SIGINFO when LIBPTHREAD_DEBUG is defined in the environment.

Eliminate a race condition in timed waist (cv, mutex, sleeps).

Don't forget to init a TAILQ before using it.

Added two additional Intel PCI ids for fxp 10/100 Pro NICs.

Don't set CR0_NE and CR0_MP in npx_probe() as they are already set earlier in cpu_setregs().

If we know this CPU has a FPU via cpuid, just assume INT16 and make the dmesg quiet.  This is true for all Pentium class processors and even some 486DX systems.

Fix bug in malloc_uninit():
Releasing items from the mt_zone can not be done by a simple uma_zfree() call since mt_zone is allocated with the UMA_ZONE_MALLOC flag.  Use uma_zfree_arg instead and supply the slam.

This bug can cause panics in low memory conditions while unloading kernel modules containing MALLOC_DEFINE(...) statements.

This commit brings kern_malloc.c up to FreeBSD 6.1 release equivalency.

Remove pidfile reference so ntpd can be stopped using the rc mechanisms.

*** empty log message ***

Fix standards section as we renamed -p to -D.

A new flag, -p, was added to cat which allows dates to be prepended to each line of output.  This could be useful when logging from scripts, etc.

The format is based on strftime
so cat -p %D test might print out
09/08/06testing this
if the file test contained testing this.

This is based on a patch floating around FreeBSD-Current.

Vulnerability in OpenSSL where bytes are ignored in keys around the signature.

Added psm ID's for glide point devices commonly found on laptops. Brings PSM support to FreeBSD 6.1 release.

Patch for ppp(4) buffer overflow

rdate's -c flag was not working as -DLEAPSECONDS was not used in the base system to maintain posix compliance.  Instead, rdate was altered to read a "right" subdirectory just as openbsd does.  In right, leapsecond versions of all the zones are built so that we can maintain legal time if needed.

Go back to PHK malloc.  Development version accidently commited.

Added hack so that ^L clears the screen.

The old ntpdate program displayed the clock error by default.  Change rdate to do the same thing.  Idea from DragonFly.

Import of OpenBSD's rdate utility.  Leapseconds flag disabled until a decision is made on /usr/share/zoneinfo/Right/UTC or equivalent.

Changed groff so that man files now say MidnightBSD

Removed ntpdate rc script.. forgot to fix makefile.

Finishing up the OpenNTPD commits.  Since we no longer have ntpdate, i'll simply have to add rdate later.

Adjusted path to config file to point to /etc/ntpd.conf instead of /usr/local/etc/ntpd.conf

Do to naming conflicts, openntpd had to be commited to its own directory src/contrib/openntpd.  This commit should clean up most of the mess. I should plan these things out more carefully. :)
