bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

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

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

PR/50729: Izumi Tsutsui: Add "SMALLPROG"-like options to disklabel(8)

Make disklabel a MI tool. It will use MACHINE/MACHINE_ARCH to determine
the disklabel params as well as allowing command-line options of -M <machine>
and -B {le,be} to specify MACHINE and byteorder to be used.

branches: 1.69.2; 1.69.8;
Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

Define USE_MBR for ofppc.

Disable COMPAT_386BSD_MBRPART. The code is still here if anyone needs it
for some reason. (But I have no idea why that would be -- if you have one
of these really ancient partitions and you're about to run disklabel, you
can easily run fdisk first and change the partition type to NetBSD.)

As it stands, the code will munch FreeBSD installs under some
circumstances, which is really not acceptable behavior.

The code, along with the kernel support that's been disabled by
default for several years, and some related but less dangerous code in
sysinst, should prboably be removed entirely after -6 is branched.

Discussed on tech-kern and tech-userlevel; closes PR 44496.

This is also almost certainly the cause of PR 42521 and PR 38841.

branches: 1.66.2;
System utilities, boot programs and kernel modules are machine
(port) specific not CPU, so use MACHINE not MACHINE_ARCH.

Remove support for NetBSD/playstation2.

Don't use #ifdef __${MACHINE_ARCH}__ to enable machine dependent features.
Instead, use proper macro defined in Makefile per ${MACHINE_ARCH}.

__${MACHINE_ARCH}__ doesn't represent an architecture of tool's target
but an architecture of binaries being compiled, so required features
are not prolery enabled or unintentionally enabled on certain host
and target combinations during src/tools build.

Make dreamcast, evbsh3, and mmeye use -DUSE_MBR.
All of these ports use src/sys/arch/sh3/sh3/disksubr.c
which is MBR aware.

Convert more MACHINE tests to MACHINE_ARCH

branches: 1.61.6; 1.61.8;
The hpcsh kernel does for sure USE_MBR. Make disklabel use it too on hpcsh.
With this, it is possible to bootstrap a MBR partitioned CF card without
partitioning and disklabelling it first on another platform.

zaurus use MBR partition info.

New NetBSD/landisk port uses MBR too.

Rototil the way disklabel -r reads and writes labels.
In particular the 'read' part plays 'hunt the disklabel' in order to get a
label into a local buffer - from where it can be displayed/edited.
The 'write' part makes a separate scan of the disk looking for places to
write the label.
The main changes are:
- It can no longer write the first 8k of the mbr to the pbr (or v.v.)
- All labels on the disk (that it can find) get updated during a write
- With -A all the labels are displayed (inc. those deleted by -D)
- Addition of -D which will delete (by one's complimenting dk_magic{2}) and
existing labels before writing labels to the expected locations.
- -v gives some verbose output to stderr, -vv more etc
A better basis for processing incorrect endian labels, or labels from other
architectures.

If HOSTPROG is empty, do not pull in libutil, since we do not need it in that
case, and several host platforms do not have libutil. Fixes the build of
these programs as host tools on platforms without libutil.

Rip out the support for writing bootstrap code. installboot(8) contains
support for hp300, hp700 and vax, $MACHINE is never arm32.
Fix usage output to only contain progname() once - bug introduced in rev 1.89

Make disklabel(8) into a host-tool, "nbdisklabel." Move disklabel.c
to main.c to avoid a name collision with lib/libc/gen/disklabel.c
when we build nbdisklabel. Still todo: commit host-tool build
infrastructure to src/tools/disklabel/.

WARNS=2 is the default defined in sbin/Makefile.inc. (thanks wiz)

WARNS=2

Initial import of iyonix port.

The Iyonix is a desktop machine from Castle Technology, based on a 600MHz
XScale[tm] 80321 processor.

* Uses the bootloader from NetBSD/acorn32, which is now 32-bit compatible.
* Currently boots multiuser with a serial console.
* Device support is not yet complete.

With help from abs.

Add hp700 MD options for proper boot code handling.

* Enable SAVEBOOTAREA on i386 and amd64 (by merging the Makefile
controls with the section for the other MBR-using platforms that
already enable this)
* Don't prompt the user to "erase the previous contents of the disk"
when there's no NetBSD MBR partition; SAVEBOOTAREA is sufficient.

These fixes mean that you can create a disklabel (on an i386/amd64) on a disk
that doesn't have a NetBSD MBR partition without trashing the existing MBR.
The previous behaviour was extremely annoying when working with media such
as FAT-formatted CF cards, and didn't really protect people with such from
accidentally trashing part of sector 1 of such disks, and made it extremely
easy to trash sectors 0..15 of those disks instead.

Bring back disklabel -B for now, since hp300 installboot isn't ready
for prime time yet.

Rip out all the '-B bootblock' support, everything should use installboot(8).
(can only affect arm32, hp300 and vax ports, and doesn't affect sysinst).

playstation2 needs MBR support in disklabel(8).

x86_64 -> amd64

Handle MBRs for x86_64.

Enable USE_MBR for all arm ports.

USE_MBR on macppc too

Rename arm26 -> acorn26.

Rather than making FileCore boot block support conditional on __arm32__, make
it conditional on USE_ACORN, and define that if MACHINE is arm26 or acorn32.
This is less than optimal, and maybe we should define it for all ARM systems,
but then disklabel handling across architectures is generally a mess at the
moment.

Preserve the boot area on x68k.

move showinfo() and showpartition() into separate file, for use by
other programs. slightly change argument signature so that globals
aren't depended upon.

MBR on cobalt too.

also use mbr partition table on prep.

- use MBR partition table also on arc.
- use defined(USE_MBR) instead of defined(__i386__), like hpcmips and arc.

Add '-DSAVEBOOTAREA' to keep MBR partition information
when NetBSD partition starts at sector 0.

On NetBSD/alpha, go out of the way to read the boot area's contents if -r

i386 now uses "installboot" for installing boot blocks. Comment out
the CFLAGS+= -DNUMBOOT=2 for now.

Remove -g

Off by one.

Nuke obsolete special case .if for amigas.

Jason says: Use getmaxpartitions(3) to determine the number of partitions
allowed in this architecture.

Add -i (interactive mode to create/edit labels) inspired by the SunOS/Solaris
format/partition command.

don't define NUMBOOT on the alpha, any more. boot block installation
is now done by /usr/mdec/installboot.

Changed to use only one bootblock file on VAX.

Added vax for 2-file boot blocks.

convert to new RCS Id conventions; reduce my headache

NUMBOOT == 2 on the alpha, too.

kill unnecessary .include.

specify man pages the new way.

pull in bsd.own.mk by hand, early, so NOMAN= can be defined there.

Finish 4.4-Lite merge, and convert to use err(3)/warn(3) functions.

disklabel(8) from 4.4 merged with our old disklabel(8) by John Brezak
(brezak@apollo.hp.com). hp300's can now disklabel by themselves.

added -D${MACHINE} for amiga's becuase of differing sizeof (struct disklabel)

Add RCS identifiers.

Use ${COPY}, not -c for install.

Don't build man page if NOMAN set.

make user the cat5 dir exists before trying to install man page there.

changed "Id" to "Header" for rcsids

added rcs ids to all files
