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.

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.

Add smaller versions of fsck_ffs(8) and newfs(8) for install media, where
support for Endian-Independent FFS and Apple UFS is disabled unless FFS_EI=1
and APPLE_UFS=1 are added to CRUNCHENV, respectively.

This reduces the size of ramdisk image for atari by over 15KB.

Thanks tsutsui and christos for their useful comments.

branches: 1.39.14; 1.39.18;
Don't depend on HAVE_GCC being always defined.

branches: 1.38.2;
remove most of the remaining HAVE_GCC tests that are always true in
the modern world.

branches: 1.37.2;
merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

branches: 1.36.2;
Add -G, which turns consistency check errors in warnings. The
current testing purpose is to create a file system with
block size > MAXPHYS.

(the check doesn't make that much sense anyway in these days of
mobile file systems, since we're interested in MAXPHYS where we
attempt to mount the file system, not where we happen to create it)

Push the mount path for mount_mfs through realpath().
This matches what other fs do.
Fixes PR/20362

Remove debuging CFLAGS.

Add support for DIOCGDISKINFO to disk like device drivers. Change
partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.

No objections on tech-userlevel@.

Wrap compiler-specific flags with HAVE_GCC and HAVE_PCC as necessary. Add a few flags for PCC.

branches: 1.31.18; 1.31.22;
- Deal with wedges and the new disk geometry structures, instead of using
struct disklabel.

Functionality lost:
1. struct disklabel used to be updated to contain bsize, fsize, cpg.
This information was used to locate the alternative superblock in
the filesystem if the primary superblock was corrupted. We need
to find a new place to store this information if we need this
functionality.
2. On vax SMD drives that contained bad sector lists, the newfs program
knew how to get the offset and skip to the correct location in order
to place the label.

sprinkle some -fno-strict-aliasing and -Wno-pointer-sign with GCC4.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

Use fstat(2) to get the partition size (falling back to the label on old
kernels) so that newfs works on vinum (and similar).
Kill the -V hack for vinum.
Don't bother faking up a label for -F and mfs, nothing is needed from it.
Ignore label if special doesn't match DISKPART(sb.st_rdev);
Simplifly logic for default block/frag sizes.
Update man page to match.
WARNS=3.

Remove alpha optimization hack.

no need for -I${MOUNT} & .PATH: ${MOUNT} now neither

Remove "getmntopts.c" from list of source files. getmntopts(3) is in
"libutil" now.

Add support for the Apple UFS variation on ffs
This is the bulk of PR #17345

The general approach is to use a run time deteriminable value
for DIRBLKSIZ. Additional allowances are included for using
MAXSYMLINKLEN with FS_42INODEFMT and a shift in the cylinder group
cluster summary count array. Support is added for managing
the Apple UFS volume label.

Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path

Use MACHINE_ARCH, not MACHINE.

add ugly hack for alpha to crank the optimisation level down to -O1,
because the default -O2 with gcc 2.95.3 builds a non functional newfs

remove duplicate MAN= entry

move mount_mfs(8) into separate man page

enable WARNS=2

#include machine/bswap.h and remove -lutil.

Allow creation of non-native byteorder FFS (via the '-B' option).

CFLAGS->CPPFLAGS

define WARNS?=1 for all of sbin/*

Fix compiler warnings.

Back out the .PATH.c changes. The .depend problem (and others)
will be fixed using the new .NOPATH make feature instead.

Use .PATH.c: ...

Use getmaxpartitions() from libutil, not a homegrown version.

convert to new RCS Id conventions; reduce my headache

specify man pages the new way.

Update from 4.4-Lite, with local changes.

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

Add RCS identifiers.

incorporate changes from 0-9-base to 0-9-ALPHA

branches: 1.3.2;
changed "Id" to "Header" for rcsids

added rcs ids to all files
