978778a652 Make the error message more readable when 'ld.so' cannot locate a needed
shared library.  Formerly, the message looked like this:

    ld.so: run: libjdp1.so.1.0: Undefined error: 0

The new message looks like this:

    ld.so: run: Can't find shared library "libjdp1.so.1.0"

(Where "run" is the name of the program being executed.)

b2eb280985 Fixup the "ld.so failed" message for the case when ld.so finds undefined
symbols.

An easy example to see this is to develop an X program which links
against Xt, but doesn't add -lX11 to the link line.  It will link fine,
but cause run-time errors by ld.so because of missing symbols used by Xt
defined in X11.  This patch makes the errors more readable.

6da3ef3223 Change ld.so to correctly load dependant libraries for dlopen and unload them
on dlclose.  Also correctly call constructors and destructors for libraries
linked with /usr/lib/c++rt0.o.
Change interpretation of dlopen manpage to call _init() rather than init()
for dlopened objects.
Change c++rt0.o to avoid using atexit to call destructors, allowing dlclose to
call destructors when an object is unloaded.
Change interface between crt0 and ld.so to allow crt0 to call a function on
exit to call destructors for shared libraries explicitly.

These changes are backwards compatible.  Old binaries will work with the new
ld.so and new binaries will work with the old ld.so.  A version number has
been introduced in the crt0-ld.so interface to allow for future changes.

b9aa930e44 Weak symbol support from NetBSD. This should bring us in sync with the
NetBSD ld code except for local changes for dlopen() and friends and
the hashing on the minor value of the shlibs.  We should be binary
compatible now with all their libraries.

0cd8c74ee0 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.

7f56eb7b93 Updated to recent version of Paul K.'s shlib code. This code has better
warning handling and allows for link-time warnings with a modified
version of gas.

Note: Not all of the newer bits were updated such as some of the non-x86
machine-dependant code is relevant to FreeBSD right now.

11fe93eee4 Unmap hints file when finished with it, so that it can go away
completely when ldconfig unlinks it.  If init is shared, then the
referenced unlinked copy of the hints file created by running
ldconfig in /etc/rc caused the file system to be unclean after
every reboot.

c2b2b84657 Changes from Paul Kranenburg which bring us into sync with his sources:
handling of errors through the standard err() and warn()
 more fixes for Geoff Rehmet's NULL pointer bug.
 fixes NULL pointer bugs when linking mono and nested X servers.
 supports a `-nostdlib' option.
 accept object files without a symbol table
 don't attempt dynamic linking when `-A' is given

a few variable names have chaged (desc -> fd), and the formatting has
changed which should make it much easier to track his sources.

I tested 'make world' for /usr/src and X twice with these changes.

a673d40f25 Change the private declarations from dlopen,dlclose,dlsym,dlctl
to public. These functions are also used in /usr/include/link.h,
so it looks, like they shouldn't be private.
I will ask Paul about that, if this is correct.

477937c24f 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).

lib.c:
Pull in archives containing definitions needed by shared objects.
warnings.c:
Less spurious "undefined symbol" msgs for shared library defined
symbols.
ld.c:
Do a better job of recognising data in text segments, eg. `const char []'.
shlib.c,ld/rtld/{Makefile rtld.c}
Use strsep() in stead of strtok() and restore colons in eg. env. vars.
