scsi_low was a common set of routines to do the SCSI bus sequencing
for the ncv, nsp and stg drivers. Those have been removed, so it's no
longer needed since nothing else in the tree uses it and nothing
likely ever will (it's for super-low-end 8-bit parallel SCSI cards).
stg(4) is marked as gone in 12. Remove it. There are no sightings of
it in the nycbug dmesg database. It was for an obscure SCSI card that
sold mostly in Japan, and was especially popilar among pc98 hackers in
the 4.x time frame. It was also only enabled on i386.

The buslogic scsi driver has been tagged as gone in 12 for some time

database started up.

si_addr is the address of the instruction executing at the time the
signal was sent. Populate this field with srr0, which, though not
always the case, is most often the instruction that triggered the fault.
debugf() is unnecessary for the TLB printing functions, as they're only
intended to be used from ddb. Instead, make them full DDB 'show'
commands, so now it can be written as 'show tlb1' and 'show tlb0'
instead of calling the function, hoping DEBUG has been defined.
Currently, icmp_error() function copies FIB number from original packet
into generated ICMP response but not mbuf_tags(9) chain.
This prevents us from easily matching ICMP responses corresponding
to tagged original packets by means of packet filter such as ipfw(8).
For example, ICMP "time-exceeded in-transit" packets usually generated
in response to traceroute probes lose tags attached to original packets.
This change adds new sysctl net.inet.icmp.error_keeptags
that defaults to 0 to avoid extra overhead when this feature not needed.
Set net.inet.icmp.error_keeptags=1 to make icmp_error() copy mbuf_tags
from original packet to generated ICMP response.

* read access to softc is protected by epoch();
* write access is protected by ipsec_ioctl_sx. Changing of softc fields
is allowed only when softc is unlinked from CK_LIST chains.
* linking/unlinking of softc is allowed only when ipsec_ioctl_sx is
exclusive locked.
* the plain LIST of all softc is replaced by hash table that uses ingress
address of tunnels as a key.
* added support for appearing/disappearing of ingress address handling.
Now it is allowed configure non-local ingress IP address, and thus the

appearing and disappearing on the host system.
Such handling is need, because tunneling interfaces must use addresses,
that are configured on the host as ingress addresses for tunnels.
Otherwise the system can send spoofed packets with source address, that
belongs to foreign host.
The KPI uses ifaddr_event_ext event to implement addresses tracking.
Tunneling interfaces register event handlers and then they are
notified by the kernel, when an address disappears or appears.

It appeared, that ifconfig(8) assumes `create` keyword as hostname and
tries to resolve it, when `ifconfig ifname create` invoked for already
existing interface. This can produce some unexpected results, when hostname
resolving has successfully happened. This patch adds check for such case.

SADB_ACQUIRE requests are send by kernel, when security policy doesn't
have corresponding security association for outbound packet. IKE daemon
usually registers its handler for such messages and when the kernel asks
for SA it can handle this request. Now such requests will contain
additional fields that can help IKE daemon to create SA. And IKE now
can create SAs using only information from SADB_ACQUIRE request, this
is useful when many if_ipsec(4) interfaces are in use and IKE doesn track
security policies that was installed by kernel.
