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

Notes:
- I added bsd.obj.mk and made it work with objdirs.
- I added an entry point to the linker to fix a warning.
- I made the backup of biostramp.inc silent.
- I added missing clean targets.

This needs to be tested further.

fix for building on ELF

add 32-bit register support to BIOSCALL interface

use ls, not ${LS}; remove now-unneeded Makefile.inc

BIOS trampoline is a static beast; generate it in the sources like
syscalls.h & friends, and include it when needed from the source directory.

Make the build process more sane.

re-implement BIOS trampoline as a more general-purpose, reusable trampoline.
calling interface (via a grapple in locore.s) is:
/*
* void bioscall(int function, struct apmregs *regs):
* call the BIOS interrupt "function" from real mode with
* registers as specified in "regs"
* (for the flags, though, only these flags are passed to the BIOS;
* the remainder come from the flags register at the time of the call:
* (PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
*
* Fills in *regs with registers as returned by BIOS.
*/

still some generalization to do (moving this to a better named location,
cleaning up #if tests from NAPM > 0 to something else to allow easy
sharing by other drivers)

and inspiring me to hack this one together.

Unlike in an i386 a.out assembler, where in an .align n directive n is meant
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.

Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.
