in other codes. Add cpu_set_user_tls, use it to tweak user register
and setup user TLS. I ever wanted to merge it into cpu_set_kse_upcall,
but since cpu_set_kse_upcall is also used by M:N threads which may
not need this feature, so I wrote a separated cpu_set_user_tls.

in the right order (suggested by: jhb done by rwatson).

destination windows were confused, one instead of other.
This error was masked, because first segment of just
established connection is usually smaller than initially
announced window, and it was successfully passed. First
window reannouncement corrected erroneous 'seqhi' value.
The error showed up when client connected to synproxy
with zero initial window, and reannounced it after
session establishment.

16C950. Adding it here doesn't unlock any of the cool 16C950 features
(like the 128 byte fifo, the different prescalor, etc), but it does
seem to get it working for me in light testing.

o Remove the clock interface. Not only does it conflict with the MI
version when device genclock is added to the kernel, it was also
not possible to have more than 1 clock device. This of course would
have been a problem if we actually had more than 1 clock device.
In short: we don't need a clock interface and if we do eventually,
we should be using the MI one.
o Rewrite inittodr() and resettodr() to take into account that:
1) We use the EFI interface directly.
2) time_t is 64-bit and we do need to make sure we can determine
leap years from year 2100 and on. Add a nice explanation of
where leap years come from and why.
3) This rewrite happened in 2005 so any date prior to 1/1/2005
(either M/D/Y or D/M/Y) is bogus. Reprogram the EFI clock with
1/1/2005 in that case.
4) The EFI clock has a high probability of being correct, so
only (further) correct the EFI clock when the file system time
is larger. That should never happen in a time-synchronised world.

do not correctly deal with failures. This presently risks deadlock
problems if dependency processing is held up by failures to allocate
a vnode, however, this is better than the situation with the failures.

If TCP Signatures are enabled, the maximum allowed sack blocks aren't
going to fit. The fix is to compute how many sack blocks fit and tack
these on last. Also on SYNs, defer padding until after the SACK
PERMITTED option has been added.
