ifconfig: Report link state even if media is not supported

For AF_LINK addrs from getifaddrs(2), ifa_data is struct if_data.
This in turn holds ifi_link_state which we can use to report
link status if the interface does not support media where it's normally
reported.

Based on OpenBSD.

In the concrete partitions editor, after deleting the last partition move
the menu selection to the "add a partition" entry (instead of the sentinel
line which is not an active menu entry).

(martin)

PR kern/55674:
move name space availability check from ld_nvme.c:ld_nvme_attach()
to nvme.c:nvme_rescan().
this avoids allocation of ld(4) instances for every possible
name space, even if it is not usable. it also reduces the device
node flood generated from that strategy.

When adding a new partition in the concrete partition editor, make sure
to set a pointer to the partition table interface in the new entry.
Otherwise we may end up not writing back the partitions at all, leading
to further fallout later.

make(1): add specific typedefs for lists

These typedefs are only intended to help human readers, they do not

had been hidden before by the typedef for Lst and LstNode.  Typing a few
'*' is less work than finding out which of the many types are pointers
and which aren't.

In meta.c, the variable "ln" served two completely different purposes,
which have been split again.  Register allocation is the job of the
compiler, not of the human source code reader.

make(1): clean up VarParseErrors, for proper error handling

Having a pure bitset was wrong.

Instead, there are several alternatives (parse error, eval error, undef

evaluation and VPE_UNKNOWN (only used during migration to the correct

Effectively disable the AMAP_REFALL flag because it is unsafe.
This flag tells the amap code that it does not need to allocate ppref
as part of adding or removing a reference, but that is only correct
if the range of the reference being added or removed is the same
as the range of all other references to the amap, and the point of
this flag is exactly to try to optimize the case where the range is
different and thus this flag would not be correct to use.

- The Alpha fast-soft-intrs implementation supports 2 soft interrupt levels,
  so in exception_return() ensure we clear ineligible-at-new-IPL softint
  bits from the SSIR, otherwise we could loop forever in the following
  scenario:

processing softnet -> clock interrupt -> schedule softclock

- If the softint thread blocks, it's possible to bounce back through
  the softint return trampoline at something other than IPL_HIGH.  This
  is not a problem other than it's contrary to what alpha_softint_dispatch()
  expect, so make alpha_softint_return() go to IPL_HIGH before it does
  anything else.

These two fixes make fast-soft-interrupts work on Alpha.

Correct an incorrectly quoted (unquoted, but should be) example used in

Add a description to the export command of why this quoting is required,
and then refer to it from local and readonly (explained in export as that
one comes first).

Note that some shells parse export/local/readonly (and often more) as
"declarative" commands, and this quoting isn't needed (provided the
command name is literal and not the result of an expansion) making
X=$Y type args not require quoting, as they often don't in a regular
variable assignment (preceding, or not part of, another command).
POSIX is going to allow, but not require, that behaviour.  We do not
implement it.

Implement RFC 7048, making Neighbor Unreachability Detection less impatient

RFC 7048 Section 3 says in the UNREACHABLE state packets continue to be

We adjust this slightly and move to the INCOMPLETE state after
`nd_mmaxtries` probes and then start backing off.

This results in simpler code whilst providing a more robust model which
doubles the time to failure over what we did before.

errors are returned because very few applications would look at
