When aborting collecting the content items, sometimes the "abort" state
was not cleaned up correctly, so the next run thought it was aborted
too. If that happened at the end of the multiple start/abort cycles that
happen at initialization, the content model ended up empty.

This could happen because insertContents() is called once for
every run of the content provider, even if an invalidation happens
in between. Example sequence:
    run()
    invalidate() [removes result of first run]
    run()
    insertContents() [queued for first run, retrieves result of second run]
    insertContents() [queued for second run, retrieves empty data]
We now check in insertContents() whether the content provider has a
valid root item and do nothing if it does not. This means that
insertContents() will never replace the current model data with empty
data; only invalidateContents() can do that from now on.
Further improvements:
    - Only call insertContents() if the run was not aborted; this
      reduces the number of useless objects in the event queue.
    - Remove the m_rootItem member; it was only used in the run() function.
    - Only add the root item to the list at the end of a successful run;
      there is no reason this object should be accessible from the outside
      while there are still children being added to it.

1) Make sure invalidateContents() is called whenever the help engine's
   DB readers are destroyed.
2) In QHelpContentProvider::stopCollecting(), remove all root items, as
   they are invalid now: Their child items reference DB readers that
   are going to be destroyed.

The help engines findFile() does already resolve virtual folders in
different namespaces, so the added code was superfluous. It did not
even work properly... Implement a redirect network reply, so when a
file from e.g. qtwidget is linked into qtcore, we will get the valid
url set inside the address bar. This also fixes "Bookmark" handling,
"Sync to Contents" as well as "Copy" and "Hover" actions.

  This essentially means that we stop using cleanPath, and where needed,

  original path.
- Remove com.trolltech default DocPath since this was not used anymore.
