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.

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.

Uses LFS boot code

branches: 1.17.40;
Add empty LIBCRTI= as LIBCRT0 to build sa programs without installed DESTDIR.

XXX: probabry we should have bsd.saprog.mk or something.

branches: 1.16.112; 1.16.122; 1.16.128;
merge ktrace-lwp.

Define LIB{CRT0,C,CRTBEGIN,CRTEND} as nothing, we don't need to link
against them.

branches: 1.14.10;
Convert `bootxx' to raw binary format which is what the MI installboot(8)
program needs.

branches: 1.13.8; 1.13.12;
bootxx links at 0x340000
2nd-stage boot programs choices: 0x200000,0x300000,0x400000,0x700000 (default: 0x300000)

RELOC -> RELOC_DEFAULT

branches: 1.11.2;
Use ${SIZE}, ${OBJCOPY} rather than size and objcopy.

Add -DLIBSA_NO_CLOSE

branches: 1.9.2; 1.9.4;
Use `-Ttext' switch & collect ld options in LINKFLAGS.

Completely rearrange SPARC boot code, modeling it after alpha and hp300
ports' boot programs. Also added support for loading gzip'd kernels,
useful for booting from floppy. From Jason R. Thorpe <thorpej@nas.nasa.gov>,
tested by Matthew Green <mrg@eterna.com.au> and Erik Fair <fair@clock.org>.

STRIP -> STRIPFLAG

remove header munging hack.

We don't need `rem.o'.

branches: 1.4.2;
Brr.. libkern.o is way too big for our bootxx..

Make this work with OBJ dirs.

Don't strip bootxx on installation.

Network booting; "oldmon" support; combine all functionality in single images.
Many thanks to Gordon Ross and Chuck Cranor for figuring out and testing
the old monitor (sun4) stuff.

Don't check if an array is (not) NULL, check if the string is empty.

kill extra whitespaces
reviewed by tsutsui@

We need an explicit include of <sys/exec_aout.h> here as well.

- use -Os to shrink bianries
- remove local shrinked memcpy() from bootxx.c bacause
now it's identical with __OPTIMIZE_SIZE__ libsa one
derived from src/common/lib/libc/string/bcopy.c.

Tested netboot from le0 and bootxx + boot from sd0 on SS1+.

Now that the stand/ code was converted to use memcpy(), the private
implementation of bcopy() needs to become memcpy() as well. The
simpler local implementation is needed so that the boot code doesn't
overflow the available space.

bcopy -> memcpy

Remove clause 3 and 4 from TNF licenses

branches: 1.19.40; 1.19.42; 1.19.44;
Make the loadboot() declaration consistent, use char* because it
does pointer arithmetic on the argument.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.17.10;
De-__P. ANSIify.

Same object code is generated (except in prf.c, where putchar argument
type was changed to int to match the prototype and one instrcution
changes accordingly).

strategy() in ofdev.c was not ANSIified in this sweep, b/c that
changes code generated at call sites!

Nothing in this file needs <sys/time.h>

bootblock.h:
- unify sparc_bbinfo (1064 bytes, with 256 block entries)
and sun68k_bbinfo (296 byte, with 64 block entries)
into shared_bbinfo (512 bytes, with 118 block entries),
which will be also shared by future bbinfo-using platforms
(including macppc)
- add datestamp to *_BBINFO_MAGIC strings, to prevent installboot vs
bootxx version skew.
- add macppc support

*/bootxx.c:
- migrate to new shared_bbinfo structure

installboot:
- add macppc support (still needs applepartmap support and testing)
- improve and add some more warnings & errors to installboot
- implement shared_bbinfo_clearboot() and shared_bbinfo_setboot(), which
perform the majority of the work for bbinfo-using back-ends
(rather than replicating that across multiple back-ends).

convert to <sys/bootblock.h>

Rather than using nlist(3), use a magic structure with a magic
number that installboot(8) can search for. Suggested by cgd@netbsd.org.

Fix typo of "following" in comment.

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
