(at the moment this is broken)

+more cleanup

Note: This cleanup includes the inclusion of the qvlay array
into the t_regionCharges type. This breaks the program logic
for the noco%l_noco case as it is created inside a certain
spin loop but should be created outside this loop. It is not
yet clear how this will be solved. Probably the regCharges
type should just move to cdngen and the arrays in it should
have full spin dimensions.

...it is not initialized properly any more.

Also in this commit: improved Htr to eV factor in evaldos and
                     adapted the related tests.

removed: weight, natd, nkpts,nkptd

Removed preprocessor switches CPP_SOC, CPP_INVERSION, CPP_APW, CPP_CORE.
Only a single fleur executable is built.

The kpts file was always read in dos/evaldos.f90. This was
problematic since there is no kpts file iff inp.xml is used.
In this case now the reading of kpts is skipped.

and MPI, mem & DA versions

This is now included in the eig-file, hence
two new routines in eig66_io have been created.
