if the line doesn't match ^<%d>, then treat it as a regular kernel
printf line. Previously if a kernel printf message started with "<"
it would be interpreted as a log message, often with LOG_EMERG
level. This was triggered by some printfs in sys/dev/aic7xxx/, and
can also happen with the partial lines that result if syslogd cannot
keep up with the rate of arrival of kernel messages.

- If there was an exiting dhclient running on the same interface as the
new iface that left and returned then dhclient would be told to use the
same interface twice. Dhclient would fail and exit after getting
confused. Use "sort -u" on them to ensure no duplicates.
This is a mostly a race condition on suspend and resume and how things
happen to occur.
- Check for netmask being set on an interface rather then up. An interface
can be up but not configured.

The fix in this and previous revisions combined is functionally
equivalent to the below patch against rev. 1.27 but the code is

than the switchin functions to guarantee that we're operating with the
correct tlb entry.
- Remove the post copy/zero tlb invalidations. It is faster to invalidate
an entry that is known to exist and so it is faster to invalidate after
use. However, some architectures implement speculative page table
prefetching so we can not be guaranteed that the invalidated entry is still
invalid when we re-enter any of these functions. As a result of this we
must always invalidate before use to be safe.

adjust the rusage statistics. This is to simplify the large number of
users of this interface which were previously all required to adjust the
proper counter prior to calling mi_switch(). This also facilitates more
switch and locking optimizations.
- Change all callers of mi_switch() to pass the appropriate paramter and
remove direct references to the process statistics.
mutex profiling code. As with existing mutex profiling, measurement
is done with respect to mtx_lock() instances in the code, as opposed
to specific mutexes. In particular, measure two things:
(1) Lock contention. How often did this mtx_lock() call get made and
have to sleep (or almost sleep) waiting for the lock. This helps
identify the "victims" of contention.
(2) Hold contention. How often, while the lock was held by a thread
as a result of this mtx_lock(), did another thread try to acquire
the same mutex. This helps identify the causes of contention.
I'm currently exploring adding measurement of "time waited for the
lock", but the current implementation has proven useful to me so far
so I figured I'd commit it so others could try it out. Note that this
increases the size of mutexes when MUTEX_PROFILING is enabled, so you
might find you need to further bump UMA_BOOT_PAGES. Fixes welcome.

a delay in applying the frequency adjustment. In extreme cases this
could result in marginal stability of the kernel-pll.
