Bug: 13580771
The cached value mHasAlpha on Bitmap could get out of sync with the
real value stored in the SkBitmap. Fix this by just eliminating the
cached value. This adds an extra JNI call in copy(), createBitmap(),
and setPremultiplied(), none of which are going to be significantly
impacted by the extra JNI call.

Merge AssetStream with AssetStreamAdaptor.
Add enums to the constructor for AssetStreamAdaptor to choose the

The old clients of AssetStream now get the following features of
AssetStreamAdaptor
- Debugging statements on error.
- The stream is an SkStreamRewindable.
- getLength() returns the correct value, and the old way of getting
the length (read(NULL, 0)) is no longer implemented, since it is
no longer used.
- isAtEnd() returns the correct value. ToT Skia makes it pure virtual,
so some implementation is necessary.

Deprecate Android-specific SkPaint functions.
The following functions were problematic:
const SkGlyph& getUnicharMetrics(SkUnichar, const SkMatrix*);
const SkGlyph& getGlyphMetrics(uint16_t, const SkMatrix*);
const void* findImage(const SkGlyph&, const SkMatrix*);
Replacing them with calls through SkGlyphCache solved a nasty crash
bug, so they have all been deprecated.

Changes in this patch include
[x] Long is used to store native pointers as they can
be 64-bit.
[x] Some minor changes have been done to conform with
standard JNI practice (e.g. use of jint instead of int
in JNI function prototypes)
[x] AssetAtlasManager is not completely 64-bit compatible
yet. Specifically mAtlasMap member has to be converted
to hold native pointer using long. Added a TODO to
AssetAtlasManager.java to indicate the change required.

When the Android runtime starts, the system preloads a series of assets
in the Zygote process. These assets are shared across all processes.
Unfortunately, each one of these assets is later uploaded in its own
OpenGL texture, once per process. This wastes memory and generates
unnecessary OpenGL state changes.
This CL introduces an asset server that provides an atlas to all processes.
Note: bitmaps used by skia shaders are *not* sampled from the atlas.
It's an uncommon use case and would require extra texture transforms
in the GL shaders.
WHAT IS THE ASSETS ATLAS
The "assets atlas" is a single, shareable graphic buffer that contains
all the system's preloaded bitmap drawables (this includes 9-patches.)
The atlas is made of two distinct objects: the graphic buffer that
contains the actual pixels and the map which indicates where each
preloaded bitmap can be found in the atlas (essentially a pair of
x and y coordinates.)
HOW IS THE ASSETS ATLAS GENERATED
Because we need to support a wide variety of devices and because it
is easy to change the list of preloaded drawables, the atlas is
generated at runtime, during the startup phase of the system process.
There are several steps that lead to the atlas generation:
1. If the device is booting for the first time, or if the device was
updated, we need to find the best atlas configuration. To do so,
the atlas service tries a number of width, height and algorithm
variations that allows us to pack as many assets as possible while
using as little memory as possible. Once a best configuration is found,
it gets written to disk in /data/system/framework_atlas
2. Given a best configuration (algorithm variant, dimensions and
number of bitmaps that can be packed in the atlas), the atlas service
packs all the preloaded bitmaps into a single graphic buffer object.
3. The packing is done using Skia in a temporary native bitmap. The
Skia bitmap is then copied into the graphic buffer using OpenGL ES
to benefit from texture swizzling.
HOW PROCESSES USE THE ATLAS
Whenever a process' hardware renderer initializes its EGL context,
it queries the atlas service for the graphic buffer and the map.
It is important to remember that both the context and the map will
be valid for the lifetime of the hardware renderer (if the system
process goes down, all apps get killed as well.)
Every time the hardware renderer needs to render a bitmap, it first
checks whether the bitmap can be found in the assets atlas. When
the bitmap is part of the atlas, texture coordinates are remapped
appropriately before rendering.

A change in the VM triggers a native memory error more aggressively than before,
showing that there's a bug in the logic of recycling bitmaps. Since the pixel
memory is allocated on the Java heap, nulling out the reference to that memory
in the Java level Bitmap object can cause that memory to get collected at any time.
Meanwhile, we may have a reference to that memory at the native level for rendering
purposes, causing an error if/when we access that memory after it has been collected
by the VM.
The fix is to avoid setting the reference to the pixels to null unless we are
not referring to it in native code. This is determined at the time we call
recycle() - we return a boolean to indicate whether the native code is still
using the memory. if not, the Java code can null out the reference and allow the
VM to collect it. Otherwise, it will get collected later when the encompassing
Bitmap object is collected.

Preloaded drawables now have a density associated with them, so we
can load the correct drawable if we are using a different density.
Window manager now formally keeps track of the density for each
screen, allowing it to be overridden like you can already do with
size, and relies on this density to drive itself internally and
the configurations it reports.
There are a new set of Bitmap constructors where you provide a
DisplayMetrics so they can be constructed with the correct density.
(This will be for when you can have different windows in the same
app running at different densities.)
ActivityThread now watches for density changes, and pushes them
to the DENSITY_DEVICE and Bitmap global density values for that
process.
A new am command allows you to change the density.
- Added a new custom PNG chunk that carries the layout padding ints.
- Extract the padding ticks from .9.png images and store in the chunk.
- Load the padding information at runtime into Bitmap and NinePatchDrawable.
- The new chunk is ordered first so that it doesn't cause a problem in older
versions of the platform.

* 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.
