Bug Description: Replace ds_newinst binary with perl script - remove dead code
Reviewed by: nhosoi (Thanks!)
Fix Description: This is my favorite part - removing all of the now dead code.  I also had to fix the exit code so that you could use $? to test for the success or failure of the new setup scripts.
Platforms tested: RHEL4, FC6
Flag Day: no
Doc impact: no

RHEL4_x86_64_gcc3_OPT.OBJ
The makefiles were assuming that if the string 86 was found in uname -m
it should use x86 for the arch.  However, it should only do this if
uname -m is not x86_64.  Also, for RHEL/Linux, we do not have to add the
NS64TAG just before the _OPT (or _DBG) since it's already in the arch.
Other platforms continue to use the other naming convention.  The
default naming convention for the mozilla components is
Linux2.6_x86_64_glibc_PTH_64_OPT.OBJ.  I considered using Wan-Teh's
instructions about source builds, but that would cause many changes to
be made to our makefiles, so I just changed the way we calculate the
mozilla OBJDIR name from the regular OBJDIR name.  These changes are
pretty much the same for adminutil, setuputil, adminserver, and ldapserver.

For ldapserver, I had to change nsarch (adminserver changed nsarch in a
different way).  I also got rid of the 32 bit specific setup stuff.  I
assume this was due to 32 bit NES admin server, so we can get rid of
this for the future, because we will have all native 64 bit apps. I also
went ahead and rolled in the gcc4 changes since they are safe for gcc3
as well.

1) Brandx -> Fedora
2) Pick up new internal component set (Admin SDK, Setup SDK, Admin Server)
3) Use JRE from the Admin Server package
4) Docs
  a) Componentize Docs
  b) Rebrand Docs
  c) Drop packaging Administration Guide in the external version
