Add NFSv3 support. Try NFSv3 and fall back to NFSv2.

Merge with generic libsa NFS code to minimize differences and to learn NFSv3.

libsa: nfs: Fix NFS_NOSYMLINK option for previous
Used only by mvme68k.

Align again with libsa (NFS_NOSYMLINK fix).

libsa/nfs.c: Add `LIBSA_NFS_IMPLICIT_MOUNT` compile-time option
by which nfs_mount() is automatically called from nfs_open(),
as done for nfs.c in i386/stand.

This is only functional difference b/w two copies of nfs.c.
Now, we can safely retire the latter.
XXX
It would be really nice to drop this option also. However,
unfortunately, it is too much for me at the very moment...

Fix the clang build by setting -z noseparate-code

Merge the OPT_SIZE flags. -Oz is not always producing smaller code that -Os,
so default to -Os for both, and we'll override where needed.

Override these two booters with -Oz for clang since it produces smaller code
here.

x86/dosboot: Allow NULL dereference to fetch command line arguments
DOS command line arguments are provided as struct psp at 0x0000;
see doscommain.c.

Recent versions of gcc and clang are clever enough to optimize code
block involving NULL dereference into ud2 insn.

Sprinkle -fno-delete-null-pointer-checks to doscommain.c to
prevent this behavior.

Note that dosboot.com for netbsd-9 and later was broken due to
this ``over optimization''. gcc 5.5.0 and clang 4.0.0 in netbsd-8
generate correct codes without this workaround.

XXX
Are there still use cases for dosboot.com? Does anyone want to
boot NetBSD from real-mode DOS in 2023?

x86/dosboot: Do not page-align data segment
4K alignment is too heavy burden for COM executable with 64K limit :)
Fix binary size overflow for clang/amd64.

bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
	CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
	CLANG_NO_ADDR_OF_PACKED_MEMBER
	CC_NO_ADDR_OF_PACKED_MEMBER
	GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

Fix the clang build by setting -z noseparate-code

add support for new GCC 9 warnings that may be too much to fix
right now.  new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree.  mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it.  (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.)  clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Change all platforms accordingly. -D is added if MKREPRO is not yes and

MKREPRO now either.

It just so happens we don't need -Wno-attributes if we

remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format.  ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k.  this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
  down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

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

BSSTART was only used for the (now depracated) old stand/biosboot code.

Overhaul MBR handling (part 1):

<sys/bootblock.h>:
    *	Added definitions for the Master Boot Record (MBR) used by
	a variety of systems (primarily i386), including the format
	of the BIOS Parameter Block (BPB).
	This information was cribbed from a variety of sources
	including <sys/disklabel_mbr.h> which this is a superset of.

	As part of this, some data structure elements and #defines
	were renamed to be more "namespace friendly" and consistent
	with other bootblocks and MBR documentation.
	Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
    *	Deprecated in favor of <sys/bootblock.h> (the latter is more
	"host tool" friendly).

amd64 & i386:
    *	Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
	be consistent with the naming convention of the msdosfs tools.

    *	Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
	and it's confusing to have two functionally equivalent bootblocks,
	especially given that "ufs" has multiple meanings (it could be
	a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

    *	Rework pbr.S (the first sector of bootxx_*):
	    +	Ensure that BPB (bytes 11..89) and the partition table
		(bytes 446..509) do not contain code.
	    +	Add support for booting from FAT partitions if BOOT_FROM_FAT
		is defined.  (Only set for bootxx_msdos).
	    +	Remove "dummy" partition 3; if people want to installboot(8)
		these to the start of the disk they can use fdisk(8) to
		create a real MBR partition table...
	    +	Compile with TERSE_ERROR so it fits because of the above.
		Whilst this is less user friendly, I feel it's important
		to have a valid partition table and BPB in the MBR/PBR.

    *	Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
	with other platforms.

    *	Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
    	we can boot off FAT partitions.

    *	Crank version of /usr/mdec/boot to 3.1, and fix some of the other
	entries in the version file.

installboot(8) (i386):
    *	Read the existing MBR of the filesystem and retain the BIOS
    	Parameter Block (BPB) in bytes 11..89 and the MBR partition
	table in bytes 446..509.  (Previously installboot(8) would
	trash those two sections of the MBR.)

mbrlabel(8):
    *	Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
	to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

Use ${MACHINE} when generating the version string, not plain 'i386'.

be consistent with other Makefiles here and invoke "rm -f" separately to ln -s

replace  "ln -sf .... $@"  with  "rm -f $@ && ln -s .... $@"
since the latter works correctly ...

Clean up machine include dir handling a tad.

Remove definition of LIBSA_SUPPORT_UFS2, the source will only build separate
ufsv1 and ufsv2 objects (the merged one was too large for the code that only
supported a single fs type).

Add support for UFS2. UFS2 is an enhanced FFS, adding support for
64 bit block pointers, extended attribute storage, and a few
other things.

This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

FreeBSD.

Revert my last change.  While it actually allows a build to finish,
an iso-image created from the resulting release won't boot.  I don't
know if this change is the source of that, but one more knowledgable
than I about the x86 booter needs to look at this, and I don't want
the waters muddied any more than necessary.

Cleanup of i386 bootloader building:
* Add separate directories for the individual netboot ROMs and

* Make sure all generated files get cleaned up.
* Set BINDIR in Makefile.inc
* Add compressed image support to pxeboot.
* Make pxeboot use the default serial console speed (9600).
