Include "opt_param.h" (ifdef _KERNEL_OPT) everywhere that MSGBUFSIZE is
referenced since some sources include <machine/param.h>.

Mostly merge changes from HEAD upto 20200411

Revert "Include opt_diagnostic.h for DIAGNOSTIC."

This did not do what I thought it did.  opt_diagnostic.h is only for
the unused _DIAGNOSTIC, which seems like an abortive attempt to
incrementally convert DIAGNOSTIC to an opt_*.h option rather than a
command-line option.

Include opt_diagnostic.h for DIAGNOSTIC.

...at least, in header files, which may not have already included
libkern.h.

New macro ALIGNED_POINTER_LOAD.

To be used with ALIGNED_POINTER(p,t) instead of writing *(const t *)p
directly.  This way, on machines without strict alignment, we can use
memcpy to pacify sanitizers, while getting the same compiled code in
the end with a single (say) MOV instruction.

Fix byte order bug in murmurhash and pacify sanitizers.
add now required includes for memcpy prototypes analogue to other hash functions

proper sizing of kmem_arena on different ports

Use and define ALIGN() ALIGN_POINTER() and STACK_ALIGN() consistently,
and avoid definining them in 10 different places if not needed.

Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions
again. This was changed in sys/socket.h r1.51 to work around fallout
from the IPv6 aux data migration. It broke the historic ABI on some
platforms. This commit restores compatibility for netbsd32 code on such
platforms and provides a template for future changes to the CMSG_*
alignment. Revert PCC/Clang workarounds in postfix and tmux.

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated

x86 changes for pcc and LKMs.

  this reduces the size of amd64 GENERIC by about 120kB, and i386 by a

  that does not need to be fast.

  In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.

We knew we were going to have to bite this bullet eventually, and there
are a couple of outstanding PRs related to this issue (9389 and 9313).
Complete solution to those PRs is going to involve some sort of run-time
decision on how large kmem_map should be, as well as changing some data
structure allocation strategies in UVM.  However, this change will at
least allow the PR submitter to simply throw resources at the problem.
