When saving to PDF we bring up the file picker UI which covers
the print UI. In this case the printing app may get killed as
it is not in the forground (the system is bound to the print
spooler so it cannot get killed). If that happens we are ending
up with an empty file. However, if the file chooser UI is up
we already have everything from the app we need and it dying
does not matter. This change takes care if ignoring printing
app death while saving to PDF.

The first issue is that the save to pdf button is enabled
before the first layout completed and at this point we do
not know anything about the document. The second is that
if a layout is in progress and we select save to pdf we
end up starting the documents UI twice and finishing the
second instance carshes the spooler.

The custom settings activity of a print serivce can change the selected
pages and the spooler was not checking whether the returned pages were
valid leading to a crash.

It is possible that a buggy app breaks the contract and provides
content to be printed in format other than PDF. This was leading
to a crash in the print spooler. This change fixes the crash and
shows a user friendly error message.

It is possible that two providers for the same page are assigned
to two preview views despite temporariliy while rebinding. We were
however releasing the provider from the view which is being bound
if not for the same page which as a result was cancelling rendering
of this page which is provided to another view via another provider.
Hence, having an empty page. Removed the unnecessary code to release
a provider when binding the view - release is happening only if the
view holder is recycled.

Saving to PDF a subset of the pages requires trimming the
undesired pages and when this is done writing the ready doc
to a URI. To write the file to URI we have to obtain it but
it is aquired by the shredding task and never released. Now
we are releasing the document immediately after trimming it.

If the user presses back before the remote print document
update has completed we get a crash. The reason is that
after the update completion we were trying to finish the
activity if we are in a cancelled state but this is not
needed as we aready handled the back key so we will finish.
Handling finish twice was creating the problem as classes
with lifecycles are not designed to be used after being
finished. In particular, we were calling doFinish() twice.

In the spooler we have the renderer reading a file to visualize
content and the app writing a file to produce the content. Since
we have to swap the file under the renderer we have a mutex file
provider that both parties can request, use when released, and
release when required. This enables us to request the file which
closes the renderer and when the renderer is closed ask the app
to write some more pages, then open the renderer, and so on. The
mutex file provider was throwing of a thread that does not own
the file thries to relase it which is not needed, this should be
just a nop.

The spooler communicates with he remote PDF renderer asynchronously.
When print is confirmed we close the renderer, destroy it, and unbind
from its service. If we unbind from the service after the print activiy
is finished we get a crash. The bug was that we did not wait until we
disconnect from the remote renderer before finishing the print activity.

When user chooses to save to PDF we open the document chooser UI.
Now if the user now backs to the print UI without choosing a file,
the print UI has all options disabled and the back button does
not work - the user is stuck. This is because we were not
transitioning the print UI in the correct state.

Removed the restriction for the page content providers to
be singletons as the RecyclerView may hold on views with
providers and ask us to bind other views for the same page.
Note that the views that RecyclerView is holding will be
soon rebound or recycled just they are not at the time we
bind other views for the same position. We were guarding
against this but caused some pages not appearing sometimes
on scrolling. Also now keeping the media size and magins
of recycled page view (will be updated if needed on
rebinding) or avoid changes of the background to null as
setting it to not null later causes an undesired layout pass.
