Include "opt_param.h" (ifdef _KERNEL_OPT) everywhere that MSGBUFSIZE is

From: Tobias Ulmer. Unbreak zfs module build on sparc{,64} by hiding DELAY.
ZFS has a conflicting definition of delay() and tries to hide it by
defining __HIDE_DELAY.

make sure MSGBUFSIZE can't expand strangely by using parens.

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

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
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Remove the (now unused) second 64k page mapped per CPU.
From matthew green, with small changes by me. All bugs are mine.

Remove INITSTACK completely - at the time we used to switch to it, we
already have access to all of lwp0 and it's uarea - so we can switch
to the correct lwp0 stack easily before calling main.

Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.
