[gtk+/gtk-3-0: 5/14] Centralize changing the operation mode in operation_mode_set()

[Federico Mena Quintero <federico src gnome org>]

commit 9b0c174e10890178a6aa4964a4863b77f522cd24
Author: Federico Mena Quintero <federico gnome org>
Date:   Tue Jul 26 16:17:43 2011 -0500

    Centralize changing the operation mode in operation_mode_set()
    
    This will be the central function to switch operation modes:  stop searches or the recent-files
    process; switch widgets, etc.
    
    We factor out the common code from recent_switch_to_browse_mode() and search_switch_to_browse_mode(),
    and remove those functions.  All the code that switched modes by hand now calls
    the central operation_mode_set().
