2a0ce8a57f Improve consistency between <sys/bswap.h> and what's actually 
defined by the C library for the various m68k ports by borrowing
some #ifs from the i386 port.

Also, align sun2 with the other m68k ports as to whether they
define __bswap{16,32} or bswap{16,32} in their C library (all
now define the __ variants).

This should make the m68k ports build sys/rump again, except
for sun2 which hits another problem later on.

17c77a58f0 Fix SIGBUS issues on strict alignment issues. Use le32dec in RMD160 
as the data pointer to RMD160_Update doesn't have to be aligned.
In SHA256_Update and SHA512_Update, only operate directly on the passed
in data if no left-over in the context exists and the data is correctly
aligned. The problem was exposed by the audit-packages rewrite in C
and reported for the libnbcompat version in PR pkg/36662.

dba01be393 Apply the patch, with some minor tweaks, supplied in PR/36513. 
This prevents a possible prefetch past the end of the source buffer.

Note that the semantics of the pld instruction mean that it is unlikely
that this would have caused any problems except in very specific
circumstances in some types of device drivers.

b8bbfca272 Don't do DIAGASSERT against NULL if _KERNEL This puts us back to 
kernel behavior before src/common where 0 was a valid dest addr.

This should fix the macppc (and other OEA ppc) silent-death-on-DIAGNOSTIC
issue, and possibly other DIAGNOSTIC failures.

XXX it might be worth thinking about an API where 0 is allowed in
documented cases and not allowed otherwise.
