dladdr(3) is in POSIX-2024, though the structure type was renamed
to match Solaris and _not_ match glibc/BSDs and no one caught it
before publication. Provide the new name but keep providing the
existing names under the same conditions as before. Update #include
visibility and dlfcn(3) manpage and add restrict qualifiers.

Add #define for RTLD_NOLOAD missed in last ld.so commit.

add RTLD_NODELETE support

if RTLD_NODELETE isn't POSIX, it is widely deployed: at least linux,
freebsd, dragonfly, netbsd, solaris, illumos, apple, and fuchsia have
it.

Implement a DL_REFERENCE dlctl. To be used by the upcoming
__cxa_thread_atexit() implementation.

ok guenther@

dlerror() should not return const char *, as noted by landry
ok guenther

More compliance fixes: hiding non-standard stuff behind __BSD_VISIBLE,
making files stand-alone, some __restrict additions.

tweaks kettenis@; ports testing and fixes landry@ and jasper@

based on a diff from Matt Provost: allow printing of ldd information
on libraries themselves. Works by setting up the debugging flags then
calling dlopen() to do the heavy lifting. ok drahn

Provide hook so that rthreads can provide a spinlock to protect from races
in lazy binding. ok art@, kurt@

add dladdr() support and add some 'standard' dlsym() support.

Add defines for missing RTLD_, eg RTLD_GLOBAL and RTLD_LOCAL,
values for RTLD_GLOBAL and RTLD_LOCAL are same as solaris uses.

Add DL_SETTHREADLCK. "pretty obviously safe i think" teddu@

correct prototype for dlerror.

dlopen and dlsym take const char * parameters.
Fix prototypes, propagate const where applicable.

Well, as we are heading for a release people are encouraged to rebuild their
entire trees for testing anyway, I might as well do this intrusive touching
of include files now. Added openBSD tags.
