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.

For a.out mode, ignore shared libraries that don't have at least 2

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.

ELF preparation step 2:

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...

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.

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.

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

This should be brought into -stable.

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.
