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.

Remove -g from CPPFLAGS.

Don't depend on HAVE_GCC being always defined.

branches: 1.2.2;
remove HAVE_GCC == 4 conditional

fix typo

newfs_v7fs(8)'s -v and -P options are obsolete. changed to newfs(8) compatible -V option.

Fix warning message.

Check whether superblock is writable sector.

Fixed the problem that partition size over 8GiB(v7fs filesystem limit) failed newfs.

Use howmany() macro as it is used in a lot fo places in this tool anyway
as suggested by Tsugutomo Enami.

Allow cross-compiling from Linux

Don't use roundup2(9) (which should have been howmany(9) anyway) to
fix builds on platforms other than NetBSD.

In sources that get compiled into the tools version of makefs, add:

#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif

This should fix cross-build problems, but I can't really test
that now, so I am not re-enabling the inclusion of v7fs support
in makefs.

fix freeblock count bug.
