intro.5: Crossreference ascii(7)
Since the beginning, Unix has included an ASCII chart. Over the last
half a century to this day, the most common format for lexographical
organization in files is according to ASCII. Consistency is maintainable
and for that reason, crossreference ascii(7) promenently in the
introduction to the File Formats Manual. Additionally, this demonstrates
the often softer style of bullet lists in the manual tradition.

powerpc/trap: Change prediction of NOFAULTING in trap_pfault()
This was probably intended to match the amd64 check, but that tests
NOFAULTING against non-zero, while this checks against 0. We're most
likely to end up in this function when faulting is allowed, so
predict_true is the better option.

libc/getaddrinfo(2): return EAI_AGAIN on nameserver timeout
A nameserver timeout is a soft failure, future attempts may succeed.
Returning EAI_AGAIN is crucial for API users to tell a soft name
resolution failure from negative resolution result.
Before the change we would return EAI_ADDRFAMILY, which I believe, is a
regression from 144361386696, and before that revision we used to return
EAI_NONAME in most of the cases.

libc/tests: enable getaddrinfo(1) tests from NetBSD
Enable running of contrib/netbsd-tests/lib/libc/net/getaddrinfo without
modifications to the test program itself. However, create our own version
of expected results files. They are produced from the NetBSD files, with
the following list of changes:
o AF_INET6 value is different, hence: s/family 24/family 28/.
o SCTP result (socktype 5 protocol 132) needs to be added to many queries
results.
o NetBSD libc sorts multiple results first by protocol, then by address
family. FreeBSD first sorts on address family, then on protocol. Some
results need to be reordered.
o Error strings need to be fixed:
s/hostname nor servname provided, or not known/Name does not resolve/
s/ai_family not supported/Address family not recognized/
s/servname not supported for ai_socktype/\
Service was not recognized for socket type/.

libc/tests: add getaddrinfo test
A test suite for getaddrinfo(3) written in C. Unlike NetBSD test, this
one will be mostly focused on what the API should return when something
isn't good with your DNS. Test emulates bad DNS servers in resolv.conf
intercepting fopen(2) and emulates downed network intercepting send(2).
Initial version covers three main scenarios: all good, server(s) timed
out, network down. For each scenario we test hostname with trailing dot
and without, since libc resolver uses quite different code paths,
sometimes even yielding with different error codes. All current error
codes in the test are what our libc returns right now, meaning the test
documents what we have, not what there should be.

mount_nfs: make temporary DNS failure non-fatal with background mode
Typical problem with network mounts is remote equipment not being
available when our host boots up after a power failure. Even if you
properly configure boot order of all local services and wait for link
coming up on your NIC, you still may boot faster than some intermediate
switch on the network or the DNS server itself. Let's refer to this as a
"server room boot race". For NFS mounts with hostname in hosts(5) the
race is addressed by a retry loop on NFS mount timeout. However, a DNS
resolution timeout is treated differently to NFS mount timeout. We fail
on the former and keep retrying on the latter.
With feedback received on current@, I see that the problem is so old, that
people got used to it and see it as a desired behavior rather than a
problem. And for those who is affected by the problem, they suggest
hosts(5) as a solution. Note that using hosts(5) isn't scalable, and
using bare IP addresses is neither scalable, nor compatible with
Kerberized mounts.

kern.opts.mk: Remove EFI from riscv BROKEN_OPTIONS
This discrepancy previously caused `make makeman` to warn
`riscv/riscv64: ignoring duplicate option EFI`. Make the kernel EFI
option consistent with EFI's per-arch defaults in src.opts.mk to remove
the warning. Note that we do build EFI boot programs for RISC-V.
This is a NFC because the only component gated by the kernel's EFI
option is sys/modules/efirt, which is also inside of a MACHINE_CPUARCH
block that excludes riscv64 anyway.

pfctl: Split pool parsing into separate functions
The pf pools are used in NAT, route-to and af-to rules. Some parts of
code are duplicated between them. Create functions apply_redirspec(),
apply_nat_ports() and apply_rdr_ports() to handle the common tasks.
Simplify data structures used for pool parsing. Move the contents of
struct redirection to struct redirspec. Map all ways of parsing pools
directly onto struct redirspec. Name various forms of struct redirspect
to hint where they are used.
Remove struct redirspec *rroute from struct filter_opts, because
filter_opts is bzero()'ed after the route part of rule is parsed, and
thus can't be used.
Add tests to ensure that parsing and error messages behave as expected.
The tests have been written and tested with pfctl from before this
patch.
