Add write_double_precision run option for KKRhost and read_doubleprecision testflag for kkrimp to use doble precision kkrflex_green files instead of single precision files

also add test option write_tmat_all
and make KKRimp and KKRhost compile simultaneously

tried to provide a consistent interface to the new wrappers for the scattering solutions; disabled old rllsll

fixed/improved interface to godfrin (invmode=3); also fixed one bug in the godfrin module; added block partitioning utility

Just the rename and two lines in the cmake files.

Changed some input arguments so that the module does not depend on any things specific to KKRhost anymore.

mkdir -p build
make tfQMRgpu SMP=openmp tfQMRgpu=yes
make SMP=openmp tfQMRgpu=yes -j

Adopted MakeFile, swiched off grouping and changed transposition flags for gpu call.

Adds in input possible specification of the a_log parameter of the exponential mesh. Removes hard-coded a_log.

This fixes issue #130 and it was found by Juba Bouaziz
