a1e5be4482 The type of some aout header types changed to uint_32, so now we need 
to cast to long before printing. While I'm here, raise WARNS to 6.

10f106f5fd Fix a few WARNS: 
1) Include string.h for strcpy.
2) Don't make duplicate declaration of dump_file, we now include extern.h.
3) Help out with some constness.
4) Cast to slightly better types in some comparisons.

d1cf9ea2c4 Fix a problem with RTLD_TRACE flag to dlopen(3), which sometimes can return 
even if there was no error occured (when trying to dlopen(3) object that
already linked into executable which does dlopen(3) call). This is more
proper fix for `ldd /usr/lib/libc.so' problem, because the new behaviour
conforms to documentation.

Remove workaround from ldd.c (rev.1.32).

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are 
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

005ba515dc Fix a tiny bug in shlib support of ldd(1); if dlopen(lib, RTLD_TRACE) 
returns, exit gracefully with 0.

This fixes the behavior you see when you specify libc.so.  It occurs
because ldd(1) itself is linked with libc.so.

	$ ldd /usr/lib/libc.so
	/usr/lib/libc.so:
	ldd: /usr/lib/libc.so: (null)
	/usr/lib/libc.so: exit status 1

5e6220d9d0 * include/elf.h has been repo copied to include/elf-hints.h, and it no 
longer includes machine/elf.h.
* consumers of elf.h now use the minimalist elf header possible.

This change is motivated by Binutils 2.11.0 and too much clashing over
our base elf headers and the Binutils elf headers.

machine-dependant code is relevant to FreeBSD right now.
