9fb4190027 Fix the ordering in the description of the dlsym() lookup procedure to
reflect src/libexec/rtld-elf/rtld.c rev. 1.68 - the globally-loaded
objects (RTLD_GLOBAL) are searched before the local object's DAG's.

f89cdf42be Mention that dlerror() is also applicable to retrieve error message after
dladdr() and dlinfo() functions calls.

7d20b8cfe0 Since POSIX gives us plenary authority to define _t types, change
__dlfunc_t to dlfunc_t to match what I have proposed to the Austin
Group.  (This also makes it easier for applications to store these
values before they decide what to do with them, e.g., in a wrapper
function.)

5bbebb88fb Reorganize dlfcn.h slightly to separate out XSI and BSD interfaces.
Add new dlfunc() interface, which is a version of dlsym() with a
return type that can be cast to a function pointer without turning
your computer into a frog.

f7a8bc4c04 Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

e206feb881 Back out my change from 6 April PDT that added a new dlversion()
function.  It was an ill-considered feature.  It didn't solve the
problem I wanted it to solve.   And it added Yet Another Version
Number that would have to be maintained at every release point.
I'm nuking it now before anybody grows too fond of it.

fd4074472e Add a new function dlversion() which returns the version number of
the dynamic linker in the same form as __FreeBSD_version.  This is
mainly intended for checking the dynamic linker version during a make
world.

4538098d0b Move the trampolines for dlopen and related functions from crt0.o
into libc.  This reduces the size of every dynamically linked
executable by 248 bytes, and it reduces the size of static executables
by a lesser amount.  It also eliminates some global namespace
pollution.

With this change in place, the source for dlfcn.h should probably
be moved to "/usr/src/include".  I'll save that for another day.

Compatibility note:  Programs which use dlopen, if compiled on
systems with this change, will not run on systems with a libc from
prior to this change.  Very few programs use dlopen, so I think
that is OK.
