The former was missed in 702547720c and
r357794 respectively.
Additionally for dc.4 and gem.4, remove on-board and SBus devices whose
support was removed as part of 58aa35d429
and r357455 respectively.
Unconditionally install bsdgrep as grep, bootstrap or not. Remove all
build glue and stop installing both gnugrep and libgnuregex now that
all consumers of the latter are gone.

In order to efficiently serve web traffic on a NUMA
machine, one must avoid as many NUMA domain crossings as
possible. With SO_REUSEPORT_LB, a number of workers can share a
listen socket. However, even if a worker sets affinity to a core
or set of cores on a NUMA domain, it will receive connections
associated with all NUMA domains in the system. This will lead to
cross-domain traffic when the server writes to the socket or
calls sendfile(), and memory is allocated on the server's local
NUMA node, but transmitted on the NUMA node associated with the
TCP connection. Similarly, when the server reads from the socket,
he will likely be reading memory allocated on the NUMA domain
associated with the TCP connection.
This change provides a new socket ioctl, TCP_REUSPORT_LB_NUMA. A
server can now tell the kernel to filter traffic so that only
incoming connections associated with the desired NUMA domain are
given to the server. (Of course, in the case where there are no
servers sharing the listen socket on some domain, then as a
fallback, traffic will be hashed as normal to all servers sharing
the listen socket regardless of domain). This allows a server to
deal only with traffic that is local to its NUMA domain, and
avoids cross-domain traffic in most cases.
This patch, and a corresponding small patch to nginx to use
TCP_REUSPORT_LB_NUMA allows us to serve 190Gb/s of kTLS encrypted
https media content from dual-socket Xeons with only 13% (as
measured by pcm.x) cross domain traffic on the memory controller.

nids(4) was a clever idea in the early 2000's when the market was
flooded with 10/100 NICs with Windows-only drivers, but that hasn't been
the case for ages and the driver has had no meaningful maintenance in
ages. It only supports Windows-XP era drivers.

As discussed on -current, -stable, -toolchain, and with jhb@ and imp@,
disable the obsolete in-tree GDB 6.1.1 by default. This was kept only
to provide kgdb for the crashinfo tool, but is long-obsolete, does not
support all architectures that FreeBSD does, and held back other work
(such as forcing the use of DWARF2 for kernel debug).
Crashinfo will use kgdb from the gdb package or devel/gdb port, and will
privde a message referencing those if no kgdb is found.

This has been years in the making, and we all knew it was bound to happen
some day. Switch to the BSDL grep implementation now that it's been a
little more thoroughly tested and theoretically supports all of the
extensions that gnugrep in base had with our libregex(3).
Folks shouldn't really notice much from this update; bsdgrep is slower than
gnugrep, but this is currently the price to pay for fewer bugs. Those
dissatisfied with the speed of grep and in need of a faster implementation
should check out what textproc/ripgrep and textproc/the_silver_searcher
can do for them.
I have some WIP to make bsdgrep faster, but do not consider it a blocker
when compared to the pros of switching now (aforementioned bugs, licensing).

Sync serial (T1/E1) interfaces are largely irrelevant today and phk
confirms this driver is unnecessary in review D23928.
This leaves ce(4) and cp(4) in the tree. They're likely not relevant
either, but glebius contacted the manufacturer and those devices are
still available for purchase. At glebius' suggestion leave them in
the tree as long as they do not impose a maintenace burden.
