sidebar outline: close auto-expanded rows and remember state

This commit adds the following features:

- Remember and restore state for rows that were manually
  collapsed and expanded by the user. To save that information
  we use two new metadata keys 'index-expand' and 'index-collapse'.

  Metadata key 'index-expand' is a string containing the GtkTreePath's
  that the user has explicitly expanded, except those already marked
  expanded by the pdf producer data. The string format is
  "|path1|path2|path3|" (starting and ending in pipe). A case with
  only one element would be "|path1|". A case with no elements would be
  the empty string "". This is to facilitate the search of the paths.

  Metadata key 'index-collapse' is a string containing the GtkTreePath's
  that the pdf producer data had them marked as expanded but the user
  has explicitly collapsed them. The string format is the same as in

- When scrolling through document, take the chance to collapse rows
  that have been automatically expanded previously. This avoids
  cluttering the tree view with too many entries when navigating
  documents that have heavily indexed outlines.
