1. Fused printers loader was not using the discovered printers to update the
historical ones. Now if a historical printer is discovered we update its state
with the discovered, i.e. most recent, information.
2. Fixed a bug in the destination adapter of the print job config dialog that
was leading to a crash if all printers item is selected when there are no
discovered printers.
3. Updated the add printers asset in the all printers screen.
4. Historical printers were not persisted by the print dialog activity.
5. Reduced the number of printers we send per transation to avoid the binder
transaction size limit. Added sending of printers in chunks in a place
this was missing.

1. Added past printer history tracking and merging favorite printers
with discovered printers.
2. Added save as PDF support.
3. Added all printers activity with search capability and optional
add printers chooser (if any print service provides add printers
activity)
4. Refactored the printer discovery session APIs. Now one session
can have multiple window discovery windows and the session stores
the printers found during past discovery periods.
5. Merged the print spooler and the print spooler service - much
simpler and easier to maintain.

1. Added a dedicated class that keeps track of the user's favorite printers
based on past usage. We keep the last 50 uses and assign a decreasing weight
to older historical use records. The printer whose records' sum is the
largest is considered the favorite for the user and so on.
2. Factored out the printer discovery logic from the print job config activity
into a separate available printers provider class. It encapsulates all the
logic to communicated with the remote print services to discover printers,
keep track of added, updated, and removed printers.
3. Preliminary scetch of the printer chooser acitivty that will show all the
printers.
