06eda379d4 64-bit clean + WARNS=6:
- Convert the (char *) cast+cast backs magic to
	  memcpy(3).  Without this, the resulting code
	  is potentially risky with higher optimization
	  levels.
	- Avoid same name when calling local variables,
	  as well as global symbols.  This reduces
	  confusion for both human and compiler.
	- Add necessary casts, consts
	- Use new style function defination.
	- Minor style.Makefile(5) tweak
	- Bump WARNS?= from 0 to 6

** for the aout code: changes are intentionally limited
   to ease maintaince.

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

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.

fa0c86aadc If a directory is world-writable or is not owned by root, skip it
and emit a warning.  This is a security measure since ldconfig
influences the shared libraries used by all programs.

I think the check should be made even more stringent by also
ignoring group-writable directories.  I will make that change soon
unless we encounter a good reason not to do it.

cfa4d73988 Add a new library function getobjformat(). It checks all the
standard places ("/etc/objformat", ${OBJFORMAT}, argv) for an
indication of the user's preferred object file format.  This
consolidates some code that was starting to be duplicated in more
and more places.

Use the new function in ldconfig.

Note: I don't think that gcc should use getobjformat(), even though
it could.  The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.

a565ca5920 Implement ldconfig functionality for ELF. The hints are stored in
a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints".
These hints consist only of the directory search path.  There is
no hash table as in the a.out hints, because ELF doesn't have to
search for the file with the highest minor version number.  (It
doesn't have minor version numbers at all.)

A single run of ldconfig updates either the a.out hints or the ELF
hints, but not both.  The set of hints to process is selected in
the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout"
or "-elf" command line option.  The rationale is that you probably
want to search different directories for ELF than for a.out.

"ldconfig -r" is faked up to produce output like we are used to,
except that for ELF there are no minor version numbers.  This should
enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports
even for ELF.

I implemented the ELF functionality in a new source file, with an
eye toward eliminating the a.out code entirely at some point in
the future.

cabb97dcbf ELF preparation step 2:
Move a.out libraries to /usr/lib/aout to make space for ELF libs.
Make rtld usr /usr/lib/aout as default library path.
Make ldconfig reject /usr/lib as an a.out library path.
Fix various Makefiles for LIBDIR!=/usr/lib breakage.

This will after a make world & reboot give a system that no
longer uses /usr/lib/*, infact one could remove all the old
libraries there, they are not used anymore.

We are getting close to an ELF make world, but I'll let this
all settle for a week or two...

d4ba5766dd Add -R (rescan or refresh) option to rescan and rebuild the hints
file based on the previous list of directories stored there which
should overcome a weakness of the '-m' switch which can only add
libs.  This is an ideal way of updating the hints list after adding
or removing a shlib since it will remove entries that are gone and
doesn't need to have all the directories spelled out each time.
(eg: rm -f /usr/lib/libtcl75*; ldconfig -R)  This only works for
version 2 hints files (which we've been generating for a year or
so) which store the path.

d66f9d22f7 Fixed a bug in the handling of the directories in the search path
that is stored in the hints file.  If that search path contained
a non-existent directory (one, say, that had been removed), and
"ldconfig -m /a/perfectly/good/directory" was run, ldconfig returned
an error status without printing an error message.  This caused
some confusing bombs when installing ports, in particular.

I changed it so that non-existent directories from the stored search
path are silently ignored.  Only non-existent directories named
explicitly on the command line are treated as errors.  Also, a
diagnostic is printed if and only if an error status is returned.

In an unrelated fix, ldconfig now silently ignores any directories
named on the command line when the "-r" option is given.  Formerly,
these directories incorrectly made their way into the "search
directories" line of the listing.  It really should be an error to
specify directories together with "-r", but I don't have time to
fix the manual page in that way right now.

2.2 Candidate.

This solves the problem of being unable to use shared libraries with dots

This should be brought into -stable.

There are more changes from Paul that look like they should be included,
but they change the format of the hints file, so I'm not going to bring them

d5453ba5c4 Make ldconfig and ld.so not hashing the shared lib minor number. This
misfeature caused troubles when a program attempted to access a shlib
where one with a higher minor number has been hashed.  Ldconfig does
only include the highest-numbered shlib anyway, so this is in no way a
limitation of generality.

Caution: after installing the new programs, your /var/run/ld.so.hints
needs to be rebuiult; run ldconfig again as it's done from /etc/rc.

 don't attempt dynamic linking when `-A' is given

a few variable names have chaged (desc -> fd), and the formatting has

09e3d49d92 This is Paul K's latest set of ld changes. A commit was necessary at this
late stage due to the fact that link.h was copyright Sun Microsystems.

This version of ld sync's us up with NetBSD's ld and supports compatablily
with NetBSD's -[zZ] flags (which we had reversed).  Compiling with this
new ld will give you RRS warnings for libraries which do not contain .type
infomation - these wsarnings are harmless and will go away as soon as you
recompile your libraries (cd /usr/src; make libraries).
