r7352: the internal heimdal build change. This changes quite a few things:

 - if you want kerberos now, you need to unpack a lorikeet heimdal
   tree in source/heimdal/. If source/heimdal/ does not exist at
   configure time then all kerberos features are disabled. You cannot
   use an external kerberos library for now. That may change later.

 - moved lib/replace/ config stuff to lib/replace/ and create a
   lib/replace/replace.h. That allows the heimdal build to use our
   portability layer, and prevenets duplicate definitions of functions
   like strlcat()

 - if you do enable heimdal, then you will need to do 'make
   HEIMDAL_EXTERNAL' before you build Samba. That should be fixed once
   I explain the problem to jelmer (the problem is the inability to
   set a depend without also dragging in the object list of the
   dependency. We need this for building the heimdal asn1 compiler and
   et compiler.

 - disabled all of the m4 checks for external kerberos libraries. I
   left them in place in auth/kerberos/, but disabled it in
   configure.in

some of the heimdal_build/ code is still very rough, for example I
don't correctly detect the correct awk, flex, bison replacements for
heimdal_build/build_external.sh. I expect to fix that stuff up over
the next few days.
