Make x68k/stand compile with GCC8. Tested with XEiJ.

Add 0x prefix when defining variables, not when using it.
This was necessary for bc(1) but it's no longer necessary.

Pass address constants from Makefile to ldscript.

Unify netboot and boot (into boot).
Now boot becomes to be able to load the NFS kernel and
netboot also becomes to be able to load the local kernel.
The only difference is the default kernel which loads.
I.e., netboot's default is nfs.

Bump boot_ustar's BOOT_MAXSIZE.

branches: 1.26.4;
Remove STRIP?=strip.
Falling back to the hosttool is not a good way now.

Remove unused variable.

Support a 'switch' command.
It displays/modifies some SRAM parameters on X680x0, like as
memswitch(1) or Human68k's SWITCH.X .
It makes easy to change the boot devices or correct the inconsistency
of SRAM/real memory size.

sample usage:
> switch show .. show all supported parameters
> switch boot=std .. set boot order to 'STD'
> switch memory=12 .. set memory size to 12MB

Merge and share boot.c between normal boot and netboot by dumb #ifdefs.

Tested on XM6i.

Be silent.

Apply the following patch submitted by Evgeniy Ivanov:
http://mail-index.NetBSD.org/tech-kern/2011/12/15/msg012226.html
http://mail-index.NetBSD.org/tech-kern/2011/12/17/msg012229.html

- add 'ls' op to struct fs_ops to support ls command on each fs,
enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

XXX1: "ls" op in fs_ops looks a bit inconsistent, but we will be able to
replace it with real fs ops like readdir if it's really worth
XXX2: someone might have to check sys/arch/ia64/stand/efi/libefi/efifs_ls.c

branches: 1.20.4; 1.20.8;
Make x68k bootloader to use MI libsa, libkern, and libz Makefiles in
src/sys/lib dirs for maintainability. Tested on X68030, ok from isaki@.

Drop bootprog_maker (formerly enabled by -M) and bootprog_date (formerly
disabled by -D) from the output of newvers_stand.sh. Change -D to the
inverted logic, so that it adds the date to bootprog_rev in ().

Change all platforms accordingly. -D is added if MKREPRO is not yes and
wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.

remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

-D_STANDALONE

Create stripped version by default.

Make these compile with the old (a.out) toolchain.

Initial commit of the new bootloader to support ELF kernel.
It consists of two programs named boot_ufs and boot; the former reads
the latter (an OMAGIC a.out).
Boot now utilizes the libsa library to read the actual kernel.

- LFS code exists, but probobly does not work.
- Currently the ELF toolchain is required.
- Many features are missing.
