Changeset 4083 for trunk

Message:

Generic PCM:
More tidying concerning OpenMP and radiative transfert routines. Ideally all
saved variables should be threadprivate (even though it is not always necessary)
It is also better practice to only read in data from file via the master core
and then broadcast the information (works for both MPI and OpenMP).
