SCons overhaul/clean-up: disentangle main build The goal is to make the build scrips more clear at first sight. So move the main build targets into a separate SConscript, to make them similar to the tests, research and tools. The final goal of this makeover is to reduce the main SConstruct as much as possible

SCons: fix the remaining shared linking problems on Ubuntu-Precise Our libraries constitute a clear dependency hierarchy, we do not want circular dependencies. Declaring these dependencies while creating the shared libraries would allow strict checking by the linker; but unfortunately this also creates transitive depdendencies stored as DT_NEEDED tags. While basically this would be just fine, the resolution of $ORIGIN on gets confused in case of transitively defined library dependencies over multiple hops, especially in case when actually no symbol of this transitive dependency is used. Since these newer systems set the --as-needed switch for linking by default, these unnecessary DT_NEEDED entries will be purged from the executable, but of course not from the shared library causing the transitive dependencies. As a consequence, when loading the executable, the $ORIGIN resolution mechanism doesn't act on the dependencies recorded in the library, causing the shared loader to abort with an "unresolved dependency" So the resolution for these problems is not to use transitive dependencies on libraries intended to be found via $ORIGIN

SCons: rework test definition to link according to layer tests used to be defined ad hoc and test definitions are scattered confusingly over various directories. Now built some simple rules into the buildsystem to allow organising the tests into layers and linking them accordingly. Note: this switches to building shared objects for the test classes too, which effectively speeds up both re-building and re-running of test cases
