patches/RELENG_8_3: stf_6rd_20100921-1.diff removal

We have 2 6rd patches, only the newer one is enabled and
was more recently changed than this one.

I guess we can wipe the older one for good.
patches/RELENG_8_3: kern_timeout.c.diff removal

This patch wasn't enabled for builds anyway.
An old jewel from the 8.0 days, disabled with 8.1 base and newer.
In the meantime the code has changed to use cc_ticks.

Reformatting the patch revealed that our change must
be included by now, no need to keep it in future:

patch-	for (; (cc->cc_softticks -        ticks) <  0; cc->cc_softticks++) {
patch+	for (; (cc->cc_softticks -        ticks) <= 0; cc->cc_softticks++) {
8.3	for (; (cc->cc_softticks - cc->cc_ticks) <= 0; cc->cc_softticks++) {

patch- 	while (cc->cc_softticks     != ticks) {
patch+	while (cc->cc_softticks - 1 != ticks) {
8.3     while (cc->cc_softticks - 1 != cc->cc_ticks) {

patches/RELENG_8_3: chflags_Makefile.diff removal

This patch wasn't enabled for builds anyway. This one was introduced
with RELENG_8_0 (2009) but even there not enabled. It doesn't tell which
Makefile it would patch and was initially made for MIPS (which we don't
do - yet). I think that we can drop it now.
rename the SMP kernel as "Standard Kernel" to hopefully reduce user confusion over SMP vs. non-SMP since SMP is now the only option.

      Permit ARP to proceed for IPv4 host routes for which the
      gateway is the same as the host address. This already works
       fine for INET6 and ND6.

      While here, remove two function pointers from struct lltable
      which are only initialized but never used.
