libcompiler_rt Makefile.inc: update _Float16/__bf16 checks
Clang supports __bf16 for riscv from version 18.0 onwards, so update the
checks for it. While here, rewrite the checks so they are hopefully more
readable, and also handle gcc a little better.
In addition, define COMPILER_RT_HAS_FLOAT16 and COMPILER_RT_HAS_BFLOAT16
when these features should be available, since there are some parts in
compiler-rt that check for these defines.

crunchgen: add --list option
"bsdbox --list" will print all tools in the binary, one per line. The
main use case for this is to make it easier to create links:
for t in $(bsdbox --list); do
ln -s bsdbox $t
done
The name --list was taken from busybox.
This just adds a new "program" with the name "--list". I don't think we
need to do real argument parsing here, and this is also how busybox does
it.
An additional minor change is that just "bsdbox" will no longer print
the binary name itself ("bsdbox" in this case). Before it would do:
% bsdbox

heimdal: Add 64-bit integer support to ASN.1 compiler
Import upstream 19d378f44:
ASN.1 INTEGERs will now compile to C int64_t or uint64_t, depending
on whether the constraint ranges include numbers that cannot be
represented in 32-bit ints and whether they include negative
numbers.
Template backend support included. check-template is now built with
--template, so we know we're testing it.
Tests included.
Also adjusts the generated files:
* asn1parse.c, asn1parse.h (not strictly necessary, but nice to have)
* der-protos.h, which needs a bunch of new prototypes. I copied these
from a der-protos.h generated by the upstream build system, which
uses a perl script for this.

networking.7 : create network quickstart guide
Now that the handbook has been moved to ports, I think it's very nice to
have a network quickstart guide in-band, in base, in the system manual.
If the user uses any of the following terms "man -k
{network,networking,wifi,quickstart}" this page will come up, which is I
think a very common use case for new users.
Currently, this document explains connecting to a basic Ethernet
network, a basic wifi network, scanning for wifi networks, and airplane
mode, as well as linking to other sections, including the handbook

nfsserver: Rate-limit messages about requests from unprivileged ports
If access from unreserved ports is disabled, then a remote host can
cause an NFS server to log a message by sending a packet. This is
useful for diagnosing problems but bad for resiliency in the case where
the server is being spammed with a large number of rejected requests.
Limit prints to once per second (racily).

tcp rack: fix sending
In rack_output(), idle is used as a boolean variable. So don't use it

This avoids setting idle to false, when it is not intended.

TCP LRO: disable mbuf queuing when packet filter hooks are in place
When doing mbuf queueing, the packet filter hooks in ether_demux(),
ip_input(), and ip6_input() are by-passed. This means that the packet
filters don't process incoming packets, which might result in
connection failures. For example bypassing the TCP sequence number
validation will result in dropping valid packets.
Please note that this patch is only disabling mbuf queueing, not LRO.
