by allreducing the measured time and using average over ranks insted

and removing one extra check

the error handling has to be thought of properly in some of the uses
of check_elpa_get/set (e.g. those outside the elpa_setup function)

mpi_comm_parent is allways requred (it was not required before, but
actually the code internals expected it to be supplied, at least for
ELPA 2 calculation OR whenever GPU was used)

C interfaces added for:

- elpa_print_settings
- elpa_store_settings
- elpa_load_settings
- elpa_autotune_print_state

Tests are done for:
- elpa_autotune_print_best
- elpa_autotune_print_state
- elpa_print_settings

There are _NO_ tests at the moment for the load/store settings C routine

Also the C interfaces for load/save autotuning are still missing

and my_prow (col) values

also adding wrapper for the backwords step
