Add common routines for command-line libwiretap error reporting.

These are similar to the routines added to ui/alert_box.c for dialog-box
libwiretap error reporting.

This centralizes the knowledge about what to say for various libwiretap
errors, removing some duplicate code, and giving more details in some
programs.
