Limit the thumbnail count to a maximum of 10 thumbnails and the app
icon count to a maximum of 20 thumbnails, instead of using a
byte-size based limit.
Also prune entries immediately when leaving recents.

I got distracted in the middle of it, and forget to finish
up with the test to not kill processes if they aren't using
an auto create binding.

In the past it's been a recommended approach to avoiding overdraw for
apps to set their window background to null at runtime if their
content view fully covers their window surface. The problem with this
is the IME.
The IME can force a resize of the window at unexpected times and
unless an app has been configured to fit system windows and manually
cover the padded area that the IME window covers, the asynchronous
nature of the IME-show process can leave surface buffer garbage
visible to the user. In previous platform versions this wasn't an
issue since pre-renderthread we would always animate a crossfade from
the closed to open state. This animation was always a bit of a hack
since it could break the contract of requestLayout/invalidate on the
view hierarchy - it could result in a draw happening into the saved
"before" state of the crossfade before a pending layout.
Now that this has been cleaned up the buffer garbage is sometimes
visible.
To prevent this, PhoneWindow now detects the state of a null window
background and draws solid rects into the area not covered by a
window's content. Which color is determined by the window context's
theme, though this is not a public API available to apps.

...are killed over eagerly.
When the current foreground activity is moving to the background,
it was briefly going through the CACHED_ACTIVITY state before the
correct LAST_ACTIVITY state, allowing its bound service processes
to be killed (because they went in to the cached list). To solve
this, as long as a process has stopping activities, it won't go
lower than LAST_ACTIVITY.
Also fixed a problem where we could put a process in CACHED_EMPTY
instead of CACHED_ACTIVITY_CLIENT. There were a number of cases
in the binding flow and also the client process state transitions
where we would not correctly updateing the bound client activity
state.
And add some sanity code so that if a process hosting a
service is killed, and a client process of that service is in the
cached state, we kill the client process. This avoids situations
where we can start thrashing around in the cached list because we
are restarting process for no reason -- since they will just
continue to be cached.
Finally, tune the process LRU list to allow twice as many cached
activity processes (from 8 to 16), so we can make better use of
the RAM we have available these days.
