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.

Replace \*(Lt \*(Le \*(Gt \*(Ge with literal < <= > >= respectively,
except for instances where \*(Le and \*(Ge are clearly understood as
mathematical symbols. Discussed with schwarze@

move the global description of --export-symbols up to dlopen,
since that's where the problem usually gets noticed,
