- Add support for Intel 965 Express chipsets.
- Add support for R200 vertex programs, along with minor bugfixes.
- Add support for vblank synchronization to pipe B of Intel hardware
(laptop screens).
bthidd(8) now was integrated with vkbd(4) and supports
multiple keyboards via vkbd(4)/kbdmux(4).
The code was tested with Apple Bluetooth keyboard and
SE k700i cell phone (remote control feature).

I found one bug. Pass our idea of TARGET_ARCH and TARGET down to
XMAKE, the cross-tools make. Previously it worked because usually
TARGET_ARCH was specified on the initial make's command line.
This should also allow us to simplify the "universe" target, which
I'm currently testing.
AEN. This makes the boot messages cleaner. I now know how this
structure works so I can implement it versus guessing. Remove the
not ready type code since it is ready now.
I added the time stamp/locale/class so people can parse messages better.
Create a sysctl so that we can set the locale/class level.
and dump_avail[] arrays so they are in sync (previously it was possible
to store more entries in the physmap[] then we could store in phys_avail[],
which was pointless). While I'm here, bump up the length of these tables
to hold 30 entries on amd64 and 16 on i386. This allows machines with
fairly fragmented memory maps to boot ok (at least one machine would
not boot FreeBSD/i386 but would boot FreeBSD/amd64 because amd64 allowed
for more fragments).

timeouts for TCP and T/TCP connections in the TIME_WAIT
state, and we had two separate timed wait queues for them.
Now that is has gone, the timeout is always 2*MSL again,
and there is no reason to keep two queues (the first was
unused anyway!).
Also, reimplement the remaining queue using a TAILQ (it
was technically impossible before, with two queues).
TSO is only used if we are in a pure bulk sending state. The presence of
TCP-MD5, SACK retransmits, SACK advertizements, IPSEC and IP options prevent
using TSO. With TSO the TCP header is the same (except for the sequence number)
for all generated packets. This makes it impossible to transmit any options
which vary per generated segment or packet.
The length of TSO bursts is limited to TCP_MAXWIN.
The sysctl net.inet.tcp.tso globally controls the use of TSO and is enabled.
TSO enabled sends originating from tcp_output() have the CSUM_TCP and CSUM_TSO
flags set, m_pkthdr.csum_data filled with the header pseudo-checksum and
m_pkthdr.tso_segsz set to the segment size (net payload size, not counting
IP+TCP headers or TCP options).
IPv6 currently lacks a pseudo-header checksum function and thus doesn't support
TSO yet.

TARGET_ARCH correctly. Now it does, even for pc98. We should suggest
TARGET=foo in preference to TARGET_ARCH because the former is
unambiguous and the latter isn't, so update the docs.
This means that a long standing gripe I've had with this comes to a
close. I can build pc98 w/o specify both things. make TARGET=arm
works (rather than trying to build a arm:amd64 image and dying badly
in the attempt).
If you specify only TARGET_ARCH, then you get the old behavior.
# we can likely simplify the UNIVERSE target now to use this, but I'm not
# up for breaking that tonight :-).
# We should consider adding some kind of sanity check for TARGET_ARCH
# and TARGET.

'ifconfig em0 tso' and 'ifconfig em0 -tso'. TSO for IPv4 and IPv6 is always
enabled or disabled together. The driver may enable only one if it doesn't
support both.
Document 'tso' and '-tso' in the ifconfig(8) man pages.

o add IFCAP_TSO[46] for drivers to announce this capability for IPv4 and IPv6
o add CSUM_TSO flag to mbuf pkthdr csum_flags field
o add tso_segsz field to mbuf pkthdr
o enhance ip_output() packet length check to allow for large TSO packets
o extend tcp_maxmtu[46]() with a flag pointer to pass interface capabilities
o adjust all callers of tcp_maxmtu[46]() accordingly

the BUGS section of the alloca(3) manpage. In particular, when
the number of TCP sockets is several tens of thousand, trying to
"sysctl -a" would SIGSEGV on the net.inet.tcp.pcblist entry (it
would exceed the stacksize ulimit, in an undetectable manner).

from both the acpi module build directory and a kernel build directory.
The latter didn't work when one attempted to build a kernel which had
"device acpi" with the "make kernel-toolchain buildkernel" command
because a cross-compiler couldn't find anything in the standard system
include path (it's empty in the kernel-toolchain case).
Fix this by passing a better root path to kernel headers (src/sys)
which works for both cases, kernel and module (-I@ only worked for
module).
Also, while here, pass -nostdinc (and a different spelling for icc) --
it's a feature that the kernel source tree is self-contained, and this
change enforces this.

bad under high load. For example with 40k sockets and 25k tcptw
entries, connect() syscall can run for seconds. Debugging showed
that it iterates the cycle millions times and purges thousands of
tcptw entries at a time.
Besides practical unusability this change is architecturally
wrong. First, in_pcblookup_local() is used in connect() and bind()
syscalls. No stale entries purging shouldn't be done here. Second,
it is a layering violation.
o Return back the tcptw purging cycle to tcp_timer_2msl_tw(),
that was removed in rev. 1.78 by rwatson. The commit log of this
revision tells nothing about the reason cycle was removed. Now
we need this cycle, since major cleaner of stale tcptw structures
is removed.
o Disable probably necessary, but now unused
tcp_twrecycleable() function.
