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.

4c6616fc3e Extend the ldconfig security check so that it ignores group-writable
directories in addition to world-writable directories.  As before,
this check can be disabled with the "-i" option, which in turn can
be made the default for boot-up by setting "ldconfig_insecure=YES"
in "/etc/rc.conf".

Also fix an mdoc nit in the manual page.

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.
