(Mostly.)
The ufs-derived ones are fake structure member macros, which are gross
and not very safe. Also, it seems that a lot of places in the lfs code
were using the ffsv1 branch of them unconditionally, and this way it's
guaranteed all those places have been updated.
Found while doing this: for non-devices, have getattr produce NODEV
in the rdev field instead of leaking the address of the first direct
block.
of non-included options was already only a warning.
This also affects redefinition and removal of file-system and makeoption
entries.

Highlights of the change are:
- Use llentry instead of llinfo to manage ARP caches
- ARP specific data are stored in the hashed list
of an interface instead of the global list (llinfo_arp)
- Fine-grain locking on llentry
- arptimer (callout) per ARP cache
- the global timer callout with the big locks can be
removed (though softnet_lock is still required for now)
- net.inet.arp.prune is now obsoleted
- it was the interval of the global timer callout
- net.inet.arp.refresh is now obsoleted
- it was a parameter that prevents expiration of active caches
- Removed to simplify the timer logic, but we may be able to
restore the feature if really needed
Proposed on tech-kern and tech-net.
lltable/llentry is new L2 nexthop cache data structures that
store caches in each interface (struct ifnet). It is imported
to replace the current ARP cache implementation that uses the
global list with the big kernel lock, and provide fine-grain
locking for cache operations. It is also planned to replace
NDP caches.
The code is based on FreeBSD's lltable/llentry as of r286629
and tweaked for NetBSD.
Use `.if !commands(xxx)' to check if `xxx' has a defined, overriden rule,
instead of `.if !targets(xxx)'. The latter evaluates as true even when `xxx'
has an empty rule to define a dependency.
used by hpcmips's NULLCONF, which doesn't even build for other causes.
If some source doen't build and needs a workaround, that should be deal with
by modifying per-file ${CC} options (e.g. COPTS.foo.c+=-fno-xxx). Let's not
use DEFWARNINGS any longer.
