  Modified files:
    lib/csu/i386         Makefile crt0.c 
    lib/libc/gen         Makefile.inc 
  Added files:
    lib/libc/gen         dladdr.3 dlfcn.c dlopen.3 
  Removed files:
    lib/csu/i386         dladdr.3 dlopen.3 
  Log:
  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.
