  Modified files:
    sys/sys              exec.h imgact.h 
    sys/i386/i386        machdep.c 
    sys/kern             kern_exec.c imgact_elf.c 
  Log:
  Update the ELF image activator to use some of the exec resources rather
  than rolling it's own.  This means that it now uses the "safe"
  exec_map_first_page() to get the ld.so headers rather than risking a panic
  on a page fault failure (eg: NFS server goes down).
  Since all the ELF tools go to a lot of trouble to make sure everything
  lives in the first page for executables, this is a win.  I have not seen
  any ELF executable on any system where all the headers didn't fit in the
  first page with lots of room to spare.
  I have been running variations of this code for some time on my pure ELF
  systems.
