time as appropriate locking review and testing can take place,
and the locking can be enabled by default.

asserts that if a thread is used for a super user check, it be
curthread. Many of these protocol entry points probably need to
accept credentials instead of threads.

it easier to configure a box to track a particular release if it does

when it won't be called. The old wording was correct, but not
sufficiently specific to understand when and how it would be called.
The new wording describes the current implementation's usage (which
should be updated if other appropriate times are decided upon),
specifically that it is called only when the load operation is
deferred to keep the locking state consistent. When the operation
isn't deferred, the calling routine is assumed to have a coherent
locking world.

buffers with kqueue filters is no longer required: the kqueue framework
will guarantee that the mutex is held on entering the filter, either
due to a call from the socket code already holding the mutex, or by
explicitly acquiring it. This removes the last of the conditional
socket locking.
elementary exercising of kqueues on datagram and stream sockets. Note
that the datagram write kqueue case is left untested due to potentially
confusing behavior for the developer (me) that might require attention.
Set the DMA SGL length correctly if the DMA request must be chained because
it is too large to fit in one SGL.

64 bit systems, years roughly -2^31 through 2^31 can be represented in
time_t without any trouble. 32 bit time_t systems only range from
roughly 1902 through 2038. As a consequence, none of the date munging
code for all the various calendar tweaks before then is present. There
are other problems including the fact that there was no 'year zero' and
so on. So rather than get excited about trying to figure out when the
calendar jumped by two weeks etc, simply disallow negative (ie: prior to
1900) years.
This happens to have an important side effect. If you bzero a 'struct
tm', it corresponds to 'Jan 0, 1900, 00:00 GMT'. This happens to be
representable (after canonification) in 64 bit time_t space. Zero tm
structs are generally an error and mktime normally returns -1 for them.
Interestingly, it tries to canonify the 'jan 0' to 'dec 31, 1899', ie:
year -1. This conveniently trips the negative year test above, which
means we can trivially detect the null 'tm' struct.
This actually tripped up code at work. :-/ (Don't ask)
