Jenkins2 has submitted this change and it was merged. ( https://gerrit.asterisk.org/7336 )

Change subject: CLI: Refactor ast_cli_display_match_list.
......................................................................

CLI: Refactor ast_cli_display_match_list.

* Stop estimating line count, just print until we run out of matches.
* Stop freeing entries, the caller does that anyways.
* Stop calculating / returning numoutput, it was ignored.
