  lib/gis: Add a helper function to determine the number of threads for OpenMP (#3929)

* determine the number of threads for OpenMP in opt parser

* add OpenMP library paths

* solve segfault when nprocs option is not specified in the command

* only change nprocs for C module

* update the description of the function, which does not return any value

* add helper function, left parser unchanged

* return threads rather than change the answer of nprocs

* modify code based on review comments

* remove threads > logic cores check, update based on review comments
