[gtk+/gtk-style-context: 21/191] GtkStyleContext: Add gtk_style_context_[gs]et_path()

[Carlos Garnacho <carlosg src gnome org>]

commit a22bfb301963a61d9303b8f6ddec981422593440
Author: Carlos Garnacho <carlosg gnome org>

    GtkStyleContext: Add gtk_style_context_[gs]et_path()
    
    This relates a GtkStyleContext with a widget path, so
    all style querying would happen based on it.
