1. For an app to print it creates a PrintDocumentAdapter implementation
which is passed to the print dialog activity. If the activity that
created the adapter is destroyed then the adapter, which may rely on
the activity state, may be in an invalid state. For example, an app
creates an adapter and calls print resuting in the app activity and
the print dialog activity being stacked. Now the user rotates the
device which triggers the recreating of the activity stack (assume the
app does not handle rotation). The recreated print dialog activity
receives the intent that originally created it with containing the
adapter that was constructed in the context of the old, now destroyed,
app activity instance.
To handle this we are limiting an app to be able to print only from
and activity and when this activity is destroyed we mark the adapter
as invalid which will result in hiding the print dialog activity. Note
that if the app process is killed we already handle this in the print
dialog activiy by registering a death recipient on the adapter binder.
2. In the PrintManager.PrintDocumentAdapterDelegate some of the state is
accessed only on the main thread and some from miltiple threads. The
code was trying to avoid locking for state that is not accessed by
multiple threads but this is error prone and the benefit does not
justify the complexity and added fragility. Now grabbing a lock all
the time.
3. The PrintJobConfigActivity waits for it to bind to the print spooler
service before instantiating its print controller and editor. However,
these can be accessed by invoking some of the activity cycle callbacks.
This change is adding null checks for the case where the activity
callbacks are called before the binding to the spooler is completed.

Needed to do an http post instead of a get for one carrier.
Do this by putting an auto-submitting form in the data to be
interpreted as a html doc by the browser. The ACTION_VIEW
intent only works on http uri, but by specifying ACTION_MAIN/
CATEGORY_APP_BROWSER we could use data:text/html.

1. We were using the layout for the printer drop down from the
print dialog as the list item in the all printers activity.
This layout was not high enough. Now we have a separate
layout for the drop down and for the list. Note that they
are almost identical but this is better that writing java
code to lookup the height from the theme and change it
programatically since the java code is almost half the size
of the layout and leads to spreading the logic in both the
layout file and the java code.
2. The padding of the printers list was not correct. Now it
mimics the bahavior in settings where we change the padding
based on orientation.
