CNE Logs: Enable logging to a file #363

Closed jalalmostafa closed 6 months ago

jalalmostafa commented 6 months ago

This PR adds an API in the logging subsystem to allow logging to a file. It adds two functions:

cne_log_set_file to the log file FILE* instance
cne_log_get_file to get the log file FILE* instance, if not set it returns stdout to keep the old logging behavior.
