adapt to ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}

Simplify CWARNFLAGS to use ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}
which works for both clang and gcc, and remove compiler-specific
equivalents.

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.

remove shadowed (common) declarations of various libsa variables
from various boot programs. for macppc and zaurus, avoid building
with -fcommon any more.

branches: 1.7.4;
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.

Use -Wno-error=address-of-packed-member for a number of more boot
loaders.

1. All Makefiles that use ARM_APCS_FLAGS add -marm unconditionally and
bsd.own.mk also adds it for gcc only (so we end up with 2 -marm for gcc).
Just add -marm unconditionally in bsd.own.mk in ARM_APCS_FLAGS and remove
it from everywhere else.
2. gcc-8 now warns about thumb internetwork in APCS mode. This does not make
sense because the documentation says that this flag does not make a
difference in apcs mode, but might produce larger code in non-APCS mode.
So we just add it to silence the warnings.

Update from the latest Zaurus source from NONAKA Kimihiro.

- LCD screen and keyboard are working now.
- Add bootstrap loader.

Make zaurus kernels use symbol tables loaded by the bootloader.

Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).

Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.

No particular comment on port-zaurus@:
https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).

Worth to pullup to both netbsd-8 and netbsd-9.

Make sure to clear bss before jumping to a kernel copied from load buffer.

This will fix yet another boot failure issue
"screen white-out after loading a kernel"
https://mail-index.netbsd.org/port-zaurus/2019/10/26/msg000072.html

Should be pulled up to netbsd-8 and netbsd-9.

Fix another boot failure issue of NetBSD/zaurus 8.x and later.

It looks some cacheline alignment restriction so that zbsdmod.o in
NetBSD/zaurus 8.x release cannot jump to a loaded kernel properly.
Adding an explicit alingment pseudo op to put all instructions
between I-cache flush and jumping to the loaded kernel into the
same cacheline solves the issue.

See my post in port-zaurus@ for details:
