When emulating a load pair or store pair in dtrace on arm64 we need to
copy the data between the stack and trap frame. When the registers are
either the link register or the zero register we will access memory
past the end of the trap frame as these are encoded as registers 30 and
31 respectively while the array they access only has 30 entries.
Fix this by creating 2 helper functions to perform the operation with
special cases for these registers.

Subsequent to r240317, kmem_free() was replaced with kva_free() (r254025).
kva_free() releases the KVA allocation for the mapped region, but no longer
clears the pmap (pagetable) entries.
An affected pmap_unmapdev operation would leave the still-pmap'd VA space
free for allocation by other KVA consumers. However, this bug easily
avoided notice for ~7 years because most devices (1) never call
pmap_unmapdev and (2) on amd64, mostly fit within the DMAP and do not need
KVA allocations. Other affected arch are less popular: i386, MIPS, and
PowerPC. Arm64, arm32, and riscv are not affected.

In r361752 an error handling was introduced for using 0.0.0.0 or
255.255.255.255 as the address in connect() for TCP, since both
addresses can't be used. However, the stack maps 0.0.0.0 implicitly
to a local address and at least two regressions were reported.
Therefore, re-allow the usage of 0.0.0.0.
While there, change the error indicated when using 255.255.255.255
from EAFNOSUPPORT to EACCES as mentioned in the man-page of connect().

initializations.
Relax some overly perscriptive rules against declarations: they may be at the
start of any blocks, even if things aren't super complicated. Allow more
initializations (those that call simple functions, like accessor functions for
newbus are fine). Allow the common idiom of declaring the loop variable in a for
loop.
This tries to codify what common exceptions are today, as well as give
some guidance on when it's best to do these things.

The code would unconditionally lock the vnode to audit or call the
mac hoook, even if neither want to do anything. Pre-check the state
to avoid locking in the common case of nothing to do.
Note this code should not be normally executed anyway as vnodes are
always return ready. However, poll1/2 from will-it-scale use regular
files for benchmarking, presumably to focus on the interface itself
as the vnode handler is not supposed to do almost anything.
This in particular fixes poll2 which passes 128 fds.

if_attach() -> if_attach_internal() will call if_attachdomain1(ifp) any time
an ethernet interface is setup *after*
SI_SUB_PROTO_IFATTACHDOMAIN/SI_ORDER_FIRST. This eventually leads to
nd6_ifattach() -> nd6_setmtu0() stashing off ifp->if_mtu in ndi->maxmtu
*before* ifp->if_mtu has been properly set in some scenarios, e.g., USB
ethernet adapter plugged in later on.
For interfaces that are created in early boot, we don't have this issue as
domains aren't constructed enough for them to attach and thus it gets
deferred to domainifattach at SI_SUB_PROTO_IFATTACHDOMAIN/SI_ORDER_SECOND
*after* the mtu has been set earlier in ether_ifattach().
