Another solution would be to extend the Makefile.sys.inc idea, or a .no_obj
file, to more places but I would rather keep that limited to the top-level
build for now to not impact performance (statting a file in every make call)
or to bring unintended side-effects.

This is already true when called via kern_getsockname() and
kern_getpeername(). This patch sets it also, when they arecalled
via soo_fill_kinfo(). This is necessary, since the corresponding
functions for SCTP require the vnet to be set. Without this,
if a process having an wildcard bound SCTP socket is
terminated and a core is written, the kernel panics.

An lld-linked i386 kernel hangs on boot, after em(4) starts. This seems
similar to the issue that prompted us to disable VIMAGE on arm64 in
r326179. Disable VIMAGE on i386 for now while we investigate.

The NetBSD tests for vmstat are basically just a smoke test, ensuring that
executing `vmstat` and `vmstat -s` exit successfully. This is more than we
test now, so go with it.
Plan A mmap()'s the entire input file and operates on it in memory. The
map(2) call succeeded, so we shouldn't need to bother checking for the NUL
byte as long as we're within our buffer space.
This was clearly intentional to match "the behavior of the original code",
but it creates a discrepancy between Plan A and Plan B that doesn't seem
sensible and it's not inherently wrong to allow a NUL byte.
This change was motivated by the gemspec in net/rubygem-grpc failing to
patch, despite the patch being generated with diff, because a NUL byte was
used as a delimiter in the header briefly in an otherwise text file.
An alternative was considered: to fallback to plan B if plan A won't process
the entire file due to a NUL byte, but I deemed this to be the better option
since plan A isn't failing due to memory limitations and will fail later on
if it's really dealing with a file it shouldn't be.

Highlights of the new bindings:
- ahb clock is specified as 'stmmaceth'
- The PHY to be used is now specified as phy-handle
- We must now check the parent of the node phy-handle points to in order to
discover if we're using internal PHY.
- The ephy clk/reset will be specified on the PHY node, not the emac node.
Care has been taken to ensure that we remain compatible with the older
bindings that we were previously using.

Akin to r327783 for amd64. lld has been usable for amd64 for quite some
time, but a couple of issues remained that affected i386. These were
recently addressed upstream in lld and merged into FreeBSD (r326831,
r326879, r326897, r326957), so we can now use ld.lld on i386 as well.
Similarly to amd64 this change enables lld only as the bootstrap linker
(used to link the kernel and userland libraries and executables), while
GNU ld.bfd is still installed as /usr/bin/ld and used for ports builds.
The ports collection is essentially ready to use lld as the system
linker for amd64, but many ports still have trouble with lld on i386,
because lld defaults to -ztext, disallowing relocations against readonly
segments. Thus switching the system linker (WITH_LLD_IS_LD) will happen
later on a per-arch basis.

because we need to poll for completion of the commands, but we're not

use the interrupt-driven commands rather than the polled ones. This
lead to a hang. Prevent this by also checking to see if the scheduler

because an allocation won't overflow size_t does not mean it is a sane size
