likwid-mpirun: Allow oversubsription if no performance measurements should be done but print warnings.

likwid-mpirun: No oversubscription of hosts allowed anymore. Retested skipping of shepard threads. Enhanced handling of pinning lists

 topology_hwloc : debug cache inclusiveness detection with some core/PU restricted by cgroups

Silence hwloc only for default and info verbosity levels. For debug and developer level, we also want the hwloc output

Silence hwloc. We have a multi-line warning for a Haswell EP machine with Cluster-on-Die enabled. It's annoying but everything we need works

Some changes to the accuracy tester. New script to adapt measurements to cache sizes of the target system

likwid-perfctr+perfscope: Change output behavior. If a performance group is given to likwid-perfctr, the timeline mode outputs the results of the metrics, not the raw values.

Pinning library: Pin main processes when first thread enters the overloaded pthread_create. So we can set the whole eventset at startup and first thread creation pins main processes and first thread

New counter result variable to hold aggregated results. When using multiple eventsets the counters are always reset to zero, so we need to aggregate in an extra variable

Added option to separate install prefix from image directory

don't chown files to root on install as this breaks local installs as user (and most packaging tools)
