[evolution-mapi] Use version-based GLib/GDK/GTK+ warnings.

[Matthew Barnes <mbarnes src gnome org>]

commit 5f88ac45b079eaae3419f97aa2a8b555f05b2377
Author: Matthew Barnes <mbarnes redhat com>
Date:   Wed Nov 28 17:04:57 2012 -0500

    Use version-based GLib/GDK/GTK+ warnings.
    
    Use GLIB_VERSION_MAX_ALLOWED and GDK_VERSION_MAX_ALLOWED to warn if we
    accidentally use symbols that were introduced in versions subsequent to
    our minimum requirement.
    
    Use GLIB_VERSION_MIN_REQUIRED and GDK_VERSION_MIN_REQUIRED to suppress
    deprecation warnings by version so we can clean them up incrementally.
    The initial values produce no deprecation warnings.
