For legacy reasons, some instance fields are aliased. The aliases have
the same definition but appear under different names. Support for such
fields has been added to Query/Common.hs
As aliases can cause somewhat harder to find bugs, a new test was
added as well.

Functions 'BuildVersion' and 'SplitVersion' are no longer needed by

these functions are moved to 'lib/utils/version.py' and references to

'version' is renamed 'ver' to avoid redefining the import

Because the Hs2Py constant generation infrastructure is transitional,
there are two generated 'autoconf' modules, namely, 'src/AutoConf.hs'
and 'lib/_autoconf.py'.  However, conflicting values were being
generated for Haskell and Python concerning the variables
'OS_SEARCH_PATH', 'ES_SEARCH_PATH', and 'IALLOCATOR_SEARCH_PATH'.
This patch fixes this problem by placing these variables only on the
Haskell side and generate Python constants holding the correct value.

Some paths set that are set at configure time are needed at run
time. These are exported by the Makefile. Change this to export the
"canonical", unversioned, ones. This also has the advantage, that
tools do not have to know which programs are python scripts (where,
after following all the symbolic links, you end up under
$(prefix)/share/ due to the private-module layout) and which are
binaries (where you end up under $(prefix)/lib/).

In the example, we have two nodes and 6 instances, all using external
storage. There are four small instances on one node, and two big
instances, requiring twice the amount of resources of a small instance,
on the other node. So, with respect to static data, the cluster
is already perfectly balanced. Using the default assumption of
dynamic usage, however, the cluster can be improved by moving
one small instance to the other node. The reason is, that by default,
all instances are assumed to use the same resources, and this measure
dominates, as all static resources are greatly underutilized.
