Summary:
Only supported by the pdf backend if using poppler >= 0.63
Sadly had to change the generator API
Text cancellation is a bit wobbly still since poppler has large parts
of the code where doesn't check for the cancellation flag, but that
is something that will get automagically fixed for us if the poppler
side is improved

How does it work:
* What it does is really closing and opening the file again through poppler
* This means that things that are generated in "open" time like Page, Rects, Annotations, Forms need to be updated
* For Page what we do is swap the PagePrivate so that other classes that hold Page* don't break
* Since some parts of the PagePrivate can be reused, we move them in PagePrivate::adoptGeneratedContents
* For all the commands in the undo stack we need to update the annotations/forms it refers to, added a new function to do that
* The annotationmodel needs updating it's pointers
* The widgets for the forms are reused and their form* updated
* the widgets for the videos are recreased since videos don't really hold much content (you lose the playing status on save but i think that's acceptable)
TODO: Make this work for .okular files
TODO: For files with password we will need to reload the file, asking for the password again and thus losing the undo stack, warn the user
TODO: autotests
It's straighforward implementation. Every single place, where there were call for (or with) TilesManager, now has a DocumentObserver as companion. The m_tiledManager reference in PagePrivate was changed to QMap<DocumentObserver, TilesManager>.

Just use the pointer as id :-)
This is BIC and SIC, increase the soversion now to makes sure we don't forget in the future
Patch based in an earlier patch by Bogdan Cristea <cristeab@gmail.com>
REVIEW: 109115
1) If the user had previously annotated the document with an old okular
version and the document contains existing annotations and no /Encrypt
(ie the case where annotation changes are no longer saved locally), make
Document::saveDocumentInfo write the original unmodified local
annotations back to XML, so that it seems that the original file was not
changed. If the user makes annotation changes, code from previous
patches already asks him to save them to a different document on close.
2) Ask "Save changes?" if the user has modified annotations in a .okular
archive.
BUG: 300197
3) Turned a "sorry" message in a "information" (with dontshowthisagain),
because now we also have the "Save changes?" prompt to inform the user.
4) Suppressed all annotation-related message boxes on document opening
The previous counter-based approach didn't take into account existing names used
by external annotations and names used in other pages.
Instead of creating a document-global table of used names, I used random UUIDs
as a source of unique names.
This removes the needs for Page to be a QObject (it's the PageController that connects to the jobs and emits the right signals), so it again a "cheap" object.
