/*
* This file declares all types of output functions, in order to provide well-formatted messages that a front-end can understand
*
* Basically, all data go through stdout, and all message (to user or to front-end) go through stderr
*
* In stderr:
* all messages prefixed with 'error:' will be considered fatal error, front-end may notify user to re-start backend
* all messages prefixed with 'warn:' will be considered nonfatal error
* all messages prefixed with 'info:' will be ignored (by the front-end)
*
* To display message to user only, use show_user, nothing will be prepended, and the message will be ignore if scanmem is running as a backend
