944609b233 Remove the prototypes for dlopen and related functions. They don't
belong here.  The standard place for them is <dlfcn.h>, and there is
already another copy of the prototypes there.

379be4bd69 Make a lot of include-files self-contained. I excluded the patches changing
int's to gid_t and uid_t - should I commit these, too?

Closes PR misc/2625.

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

03a8558771 Fixed the wrong include file for a "prototype mismatch" error between

417a88b9aa dlfcn.h and link.h have conflicting declarations for dlopen/dlsym,
with dlfcn.h declaring them as:

void *dlopen __P((const char *, int));
void *dlsym __P((void *, const char *));

while link.h declared them as

extern void *dlopen __P((char *, int));
extern void *dlsym __P((void *, char *));

Fix link.h to match dlfcn.h

1c0a68465c Add support for storing a -R path in ld in the section dispatch table,
support LD_HINTS_VERSION_2 that has the ldconfig pathname stored in the
ld.so.hints file (ie: a new library can be installed and used without
needing to run ldconfig -m first)

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.

9e603b0041 This is the new link.h from Paul K. Keeping history is even probably a bad
idea considering the old version (but I haven't time for attic surgery - this
is just a caution).  This is part of (and the major reason for) the new ld
changes.
