Fix errors when using urtwn(4) with xhci host cntrollers.

Openbsd had changed their xhci stack to send an empty xfer to accomodate
urtwn devices over xhci.

This achieves the same thing (but in the xhci driver itself).
The flow would be tx pkt-> empty xfer for each packet to transfer.
It also helps to schedule only one transfer per pipe at a time.

This avoids the dreaded "device timeout" condition and the wifi link remains
connected and operational.

Analysed by Harold Gutch and earlier isssues identified by Greg Troxel.

PR bin/59511

when extracting variables for filtering in NPF, allow the handler to
recursively extract all variables that might be present in the parent variable
to fully get all the filter elements present in them. this issue poses a security risk
as intruders can find their way into your machine if you intend to block them
but have their IPs in a nested variable with other IPs as well.

Improve error messages from cd builtin

Have cd indicate (particularly for when CDPATH is in use,
but also in other cases) which path name was attempted
and failed, and why it failed.  For CDPATH uses, when
(if) the cd eventually fails, prefer the first entry in
which the requested destination path is located (when
the chdir() to it fails), or if there is none of those,
the first lookup which failed to determine if the path
exists there or not (ie: not ENOENT).

If the all attempts return ENOENT simply report the arg
given (after "cd -" and "cd a b" processing), as no
one CDPATH entry is more appropriate than any other.

Inspired by PR standards/59565 but not directly related.

(kre)

PR standards/59565 - cd "" is now an error, not == cd .

POSIX 2024 requires that cd "" generate an error message,
and fail.

Until now shells (including this one) have typically equated
it to "cd ." as in the distant past, a lookup of "" as a path
name would return the current directory (aka ".").

From now on, we generate an error, as specified.
(For this commit, the error message is kind of pathetic,
but it is at least there - that will be fixed in a
subsequent commit.)

bozohttpd(8): clarifications and editorial fixes

Clarify that -b also listens on an address and port
(overridden by -i address and/or -I port), as does -f.

If -i isn't given, all addresses are listened to.
Use literal instead of emphasis for Lua, paths, URLs (etc).

Add more cross-references to other options.

Split FILES into a tagged list and subsections describing
the behaviour.

drop duplicate "by default".

Add lua.pc so pkg-config can pick it up.

I considered using lua-5.4 as most distros seem to install their .pc file
as that, but equally there is some support for just lua which seems to
reflect the system provided library which is what NetBSD ships.
