on 64bit architectures (casts from pointer types) with the AutoTools 
build system.  The old build system used to change the definition of INT
for this.  Not having to do this is more elegant, however, because these
casts really only occur at these three places.

Thanks to Bernd Flemisch and Andreas Lauser for the patch.

add new methods GetBoundaySegmentId() which allows to access a consecutive, zero-starting index for each domain boundary segment.  this is needed by DUNE

The anonymous CVS in Heidelberg does not contain this directory
for legal and historical reasons.  The Stuttgart svn does contain
it, however the diff tool (apparently) does not include the 
content of missing directories into patch files.  Hence a clean
checkout from Heidelberg with patches from Stuttgart will still
not contain chaco, and every reference to it from the build
system is an error.

- change to dim namespace

code (and you really shouldn't install this anyways) and
std_internal.h, because it is newer than the AutoTools build
system and hence there shouldn't be problems with backward
compatibility.

This helps fixing a bug in Dune.  The new implementation is
incomplete.  It leaks memory because I don't know how to
properly deallocate memory received through GetFreeList.
But it is a start.
