Move report_err.{h,c} from epan into wsutil: there's nothing epan-specific there and moving it avoids having to recompile the file for use in editcap and capinfos (which don't link against libwireshark).

+/* report_err.c
+* Routines for code that can run in GUI and command-line environments to
+* use to report errors to the user (e.g., I/O errors, or problems with
+* preference settings).
+*
+* The application using libwireshark will register error-reporting
+* routines, and the routines defined here will call the registered
+* routines.  That way, these routines can be called by code that
+* doesn't itself know whether to pop up a dialog or print something
+* to the standard error.
