sun3:

- reduce UBC_NWINS, MAXEXEC, and PAGER_MAP_DEFAULT_SIZE to recover
enough lost VA to actually run basic tests.

Poor sun3 (but not sun3x) has only 31MB KVM address space,
so reduce NKMEMPAGES_MAX_DEFAULT from 64MB to 16MB.

Make common kernel module binaries work on both sun3 and sun3x.
Tested on 3/160 (on TME) and (real) 3/80.

Refactoring MD segment related definitions on m68k ports:
- move macro SEGSHIFT, NBSG, and SEGOFFSET from <machine/param.h>
to <machine/pmap.h> where they should belong
- don't use m68k_round_seg()

- don't use m68k_round_seg() and m68k_trunc_seg() in sun3 pmap sources
and instead define and use sun3_round_seg() and sun3_trunc_seg()
since they are quite pmap implementation dependent

Move UCB-licensed code from 4-clause to 3-clause licence.

Increase MSGBUFOFF to 512 so we can be sure there is room for a
kernel core header before the message buffer.

Fix MSGBUFSIZE

Correct for the extra member in 'struct kern_msgbuf' when calculating
the number of bytes we want to allocate.

Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

Restore the define of UPAGES.

Define NBSG from (1 << SEGSHIFT) and move some variables before
<m68k/param.h>.

Use the MI <m68k/param.h> include.

Define VM_MAX_KERNEL_ADDRESS using KERN_END instead of a constant.

Allow option MCLSHIFT=x to control MCLBYTES etc.

Use ALIGNBYTES in the new ALIGNED_POINTER macro.
(That is always good enough on the m68k.)

Move sun3_btop (etc.) macros from param.h to pte.h
