- 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

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

Add SCSI host adaptor selector to "boot" command of /boot.
By this function, /boot which booted from non-SCSI
(in other words, floppy) can load SCSI kernel.
Now, single /boot can load kernel of all supported filesystems
of all supported boot devices.

---
New "boot" command's syntax is: boot [hostadaptor@][dev:][file]

If you booted from SCSI, hostadaptor is already set (from IOCS)
and you can omit hostadaptor in this case. You can type like
"boot sd0a:netbsd" as before.

If you booted from floppy (hostadaptor is not set) and want to
load the SCSI kernel (hostadaptor is needed), you have to select
your hostadaptor in boot command, like "boot spc0@sd0a:netbsd".

Revert this one; I can't tell for sure if it's using libsa gets or its

in the libsa one (a) might not work and (b) might make the bootloader
