[gtk+/multiroot-filechooser-2-20: 2/21] Update the sidebar entries based on the root URI.



commit 43cb734cfe670b68f6f8ecff2258342fd2d59733
Author: Christian Hammond <chipx86 chipx86 com>
Date:   Mon Feb 1 21:50:59 2010 -0800

    Update the sidebar entries based on the root URI.
    
    The sidebar generation code has been made more flexible so that it can be
    run more than once, instead of assuming it will only ever be run once.
    
    Various sidebar entries are now dependent on the type of root. Search, for
    example, only shows up with a file:-based root.
    
    When deciding whether a volume can be added, the root URI is checked to make
    sure the volume resides within that root.
