Physical addresses are vm_paddr_t, not vm_offset_t.  This can make a difference
when sizeof(vm_offset_t) != sizeof(vm_paddr_t).

These tests query a running process for information related to the -b,
-c, -e, and -f flags; the -f testcase is largely stubbed out, pending
additional work to determine a good, deterministic descriptor.

Core file test support is coming soon--it requires a bit more effort
due to the fact that:
- coredumps can be disabled (kern.coredump=0).
- corefiles can be put in different directories than the current
  directory, or be named something other than `<prog>.core`
  (`kern.corefile`).

function (they used to say UMA_ZONE_NOFREE), so flag parameter goes away.
The zone_fini parameter also goes away.  Previously no protocols (except
divert) supplied zone_fini function, so inpcb locks were leaked with slabs.
This was okay while zones were allocated with UMA_ZONE_NOFREE flag, but now
this is a leak.  Fix that by suppling inpcb_fini() function as fini method
for all inpcb zones.

Implement simple separate ip module and fragment re-assembly.

The work is based on send and receive previously implemented in udp.c,
moved to ip.c and added the ip fragment re-assembly.

This change allows to specify larger tftp or nfs payload, such as:
tftp.blksize=4096 or nfs.read_size=4096

The idle thread may process callouts while reloading the timer in
cpu_activeclock(). In this case, provide a representative value, &cpu_idle,
instead of 0 for args[0] so that the active thread can be more easily
identified from the probe.

This addresses intermittent failures of the profile-n/tst.argtest.d test.

operation after processor is configured to allow all required
features.

In particular, NX must be enabled in EFER, otherwise load of page
table element with nx bit set causes reserved bit page fault.  Since
malloc uses direct mapping for small allocations, in particular for
the suspension pcbs, and DMAP is nx after r316767, this commit tripped
fault on resume path.

Restore complete state of EFER while wakeup code is still executing
with custom page table, before calling resumectx, instead of trying to
guess which features might be needed before resumectx restored EFER on
its own.

The existing 'binary' test in netbsd-tests/ does a basic check of the
default treatment for binary behavior, but not much more than that.
Given some opportunity for breakage recently that did not trigger any
failures, add some tests to cover the three different binary file
behaviors (a, -I, -U) and their --binary-files= equivalent values.

Bring in some bits from NetBSD and lift the restriction in uniq(1) that
-c cannot be used with the -d and -u options.  This restriction seems
unnecessary and is supported at least by GNU, OpenBSD, and NetBSD.  Lift
the restriction and simplify the show() logic a little bit to maintain
functionality when -c is provided with -d/-u.

Also with this change, -d and -u are now actually a mutually exclusive,
albeit valid, combination.  Given that they both indicate opposite
behavior, uniq(1) will no longer output anything if both -d and -u are
supplied.  This is in line with NetBSD as well as GNU.

Adjust the man page and usage() to reflect that -c is its own standalone
option.

Check if passed phdr is actually phdr of the interpreter itself, and
decide that this is the case of direct execution.  In this case, the
binary to activate is specified in the argv[1].  After opening it,
shift down on-stack structure with argv, env and aux vectors to
emulate execution of the binary and not of the interpreter.
