list-view: add back a treeview option

Re-add most of the code that handled the tree view in NautilusListModel
and NautilusListView, cleaned up and rebased to master.

The tree mode will be activated by a checkbox in the Preferences dialog.
preferences: add a "Navigate folders in a tree" preference

Users can now enable the tree view with the checkbox.
list-view: follow the newly introduced use-tree-view GSetting

Added missing data/shell-search-provider-dbus-interfaces.xml
search-directory: enable incremental directory load

Instead of emitting nautilus_directory_done_loading() from the
"finished" callback, do it as soon as we receive the first batch of
hits. The rest of the results will be added to the directory in
background.

search-directory: always start the simple engine

This is needed to load results incrementally, which will be done in a
separate commit.

search-directory: make the simple engine recursive

search-directory: ensure we call emit_done_loading() when no results

When we receive no results, we should still call
nautilus_directory_emit_done_loading() and clear the loading state.
Do this by factoring out an idempotent helper, which will be called both
from the hits-added and finished callbacks.
query-editor: don't quote the current location name

We don't do it anywhere else in the UI for buttons that only display the
location name, and it looks strange.

search-engine-simple: make sure to query for IS_BACKUP attribute

Or we will fail to filter out backup files from search results.
