Localized optimizations in views and bitmaps
* Don't call context.getResources() redundantly when unnecessary;
similarly for Resources.getCompatibilityInfo()
* During bitmap creation, don't bother clearing to 0: it's unnecessary
because now that the raw bits are stored in a VM-side byte array, it
was cleared at initialization time. Also, don't use the sanity-
checking public entry point to erase to a color, because we know
that we're by definition in a "legal" path to erase to the initial
contents and don't need to incur the overhead of the (inappropriate)
sanity checking.

Note: The integrator of this change to Android internal code-repo will
have to run one extra step 'make update-api' to update 'api/current.txt'
file corresponding to approved API. The AOSP branch didn't have this
file, hence I could not add the same to this change. The updated file
'api/current.txt' has to be submitted along with this change.

Replace Bitmap's finalizers with PhantomReferences.
This change also removes the use of SoftReferences for View's
drawing cache.
A bitmap now creates a PhantomReference enqueued in a reference
queue provided by the new Finalizers class. This queue is polled
from a thread started after forking zygote. That thread is in charge
of clearing the references after GC runs and of calling reclaim()
on them. The reclaim() method is now how finalizers are run.
Note that a PhantomReference cannot be kept in the instance it
refers to, which is why they are kept in a separate List.

Fiddle with default densities to try to sanitize the API.
An issue with the density API is that bitmaps assumed the old default density,
so new programs would have to explicitly set the correct density for every bitmap
they create.
This is an attempt to fix that situation, by define the default density of bitmaps
to be the main screen's density, except for old apps where it is the original default
density.
Actually implementing this is not so great, though, because the Bitmap constructors
can't really know anything about who is calling them to know which density to use.
So at this level the compatibility mode is defined per-process -- meaning the initial
package loaded into a process defines the default bitmap density, and everyone else
loaded in later on has to live with that.
In practice this shouldn't be much of a problem, there shouldn't be much mixing of
old vs. new apps in a process. It does mean that, going forward, if a developer is
going to use shared user IDs for this, they will need to make sure either that all of
their apps are in the same compatibility mode, or that their code explicitly sets the
density of bitmaps it receives. This isn't all that great, but I think it is worth
the benefit of allowing people who write modern apps to not have to deal with bitmap
densities.
This change also does some cleanup of the density management (making sure to always
copy over bitmap densities, etc) and adds java docs to explain the various ways
density is set and used by the system.

Allow for screen density drawables in compatibility mode.
This change allows us to use drawables that match the current screen
density even when being loaded in compatibility mode. In this case,
the bitmap is loaded in the screen density, and the bitmap and
nine-patch drawables take care of accounting for the density difference.
This should be safe for existing applications, for the most part, since
they shouldn't really be pulling the bitmap out of the drawable. For
the small rare chance of them breaking, it worth getting the correct
graphics. Also this will only happen when there is actually a resource
of the matching density, and no existing apps should have resources for
anything besides the default density (though of course all of the
framework resources will be available in the native density).
As part of this, the bitmap density API has been changed to a single
integer provider the DPI unit density.

In the case of purgeable bitmaps, this call ensures that the pixels
