Err code struct (#1238)

Added err_info type to CLUBB to extend old err_code integer flag
CLUBB ticket #975

Created a new err_info type replacing the old err_code integer.
It contains MPI rank and (OMP) chunk index so we can identify the specific process that caused an error.
It also contains latitude and longitude so a person trying to debug a host model run can pinpoint the column that caused an error.
It contains error headers that combine all the info into a string that can be printed when an error happens.
And it comes with subroutines that handle initialization, value setting, and cleanup.

Host models will be modified accordingly.

Possible TODO: Implement a subroutine that identifies the index of the column with the error after the fact so we can have more specific info at the higher call levels by applying `where` to the err_code member array.
