calc_onsite_only testflag for KKRimp

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
