This patch set allows the PMS to parse the
mac_permissions.xml file which contains the
seinfo values. Each package that is installed
on the device will be assigned an seinfo value
based on policy. This seinfo value will help label
the app process and data directory. Modifications
include adjustments to ApplicationInfo.java
to store the seinfo tag per package as well as
adjustments to installd to communicate the seinfo
tag to libselinux.

8323587: Add feature for supporting app widgets
8323342: Add feature for replacing the home screen
8323590: Add feature for supporting input methods
The app widget service looks for the app widget feature
and refuses to work if it doesn't exist. I didn't do
this for the input method service because some devices
will probably want to still make use of that mechanism
without supporting third party input methods.

If we're using a HWC that doesn't support virtual displays, or we have
more virtual displays than HWC supports concurrently, the
VirtualDisplaySurface should simply be a passthrough from source
(GLES) to sink.
This change also tries to distinguish between display types and HWC
display IDs a little better, though there's more to do here. Probably
needs a higher-level rethink; it's too error-prone now.

HWComposer didn't allow the virtual display output buffer to be set
directly, instead it always used the framebuffer target buffer.
DisplayDevice was only providing the framebuffer release fence to
DisplaySurfaces after a commit.
This change fixes both of these, so both HWComposer and DisplayDevice
should continue to work if VirtualDisplaySurface changes to use
separate framebuffer and output buffers. It's also more correct since
VirtualDisplaySurface uses the correct release fence when queueing the
buffer to the sink.

- added a ctor that updates and dumps the stack immediately
- added a "logtag" parameter to dump()

some drivers don't support this yet, so we use a system
property to enable the glReadPixels "workaround" for them:
ro.bq.gpu_to_cpu_unsupported=1

Previously we only queued a virtual display buffer to the sink when
the next frame was about to be displayed. This may delay the "last"
frame of an animation indefinitely. Now we queue the buffer as soon as
HWC set() returns and gives us the release fence.

We're not using IMemoryHeap as a transport anymore,
instead we're providing a CpuConsumer and use the
IGraphicBufferProducer version of the screenshot API.
However, some GPU drivers don't support properly
a GPU to CPU path, to work around this, we use a
temporary BufferQueue on the server side for the
GL rendering, and we use glReadPixels into the
CpuConsumer (we're now using a CPU to CPU path
which is always supported).
Currently this "wrapping" is always performed,
but it can be bypassed on devices that support
the GPU to CPU path.
This also addresses a DoS attack vector on
SurfaceFlinger, where an application could
consume all of SF's filedescriptors by creating
a lot of screenshots in a row.

background:
we have some code to fix-up the IDs of references when
using RefBase's DEBUG_REFS when those refs are managed by
arrays wp<> or sp<> (this is because wp<> / sp<> don't have
a trivial ctor when DEBUG_REFS is enabled, and Vector
treats them as trivial for obvious performance reasons)
this is complicated by the fact that we don't want to have
to recompile everything when enabling DEBUG_REFs (i.e.: the
Vector code cannot know wheter it's enabled or not for its
template stuff).
problem:
there was a bug in the fix-up code for wp<> which was trying
to access the weakref_impl from the RefBase* however, this was
moronic since RefBase could have been destroyed if there wasn't
any more strong refs -- and this happned. Instead we need to get
the weakref_impl directly from the wp<>

* changes:
Add BufferQueueInterposer and use it for virtual displays
Add DisplaySurface abstraction
Fix argument types in IGraphicBufferProducer methods
Minor cleanups/fixes before virtual display refactoring
- stacks are now saved in /data/debug which must be
created and writable by the user.
- removed "always fatal" DEBUG_REFS option, it wasn't
really needed.
- DEBUG_REFS_ENABLED_BY_DEFAULT is not the default anymore
(usually people want to target which refs they're tracking)

BufferQueueInterposer allows a client to tap into a
IGraphicBufferProducer-based buffer queue, and modify buffers as they
pass from producer to consumer. VirtualDisplaySurface uses this to
layer HWC composition on top of GLES composition before passing the
buffer to the virtual display consumer.

DisplayDevice now has a DisplaySurface instead of using
FramebufferSurface directly. FramebufferSurface implements
DisplaySurface, and so does the new VirtualDisplaySurface class.
DisplayDevice now always has a surface, not just for virtual displays.
In this change VirtualDisplaySurface is just a stub; buffers still go
directly from GLES to the final consumer.

None of these should change behavior, except for removing some
incorrect log messages when using a virtual display.
- HWComposer::getAndResetReleaseFenceFd() checks the HWC version, so
no need to do that in the DisplayDevice::onSwapBuffersCompleted().
However, it should check that mFramebufferSurface is not NULL like
it is for virtual displays.
- Comment that FramebufferSurface::dump() overrides the non-virtual
ConsumerBase::dump(), and fix it so the right thing happens
regardless of the static type of the pointer/reference the callee
has. FramebufferSurface::dump() could be removed right now, but I'd
need to bring it back in a later change.
- Use the right enum for validating display type ids.
- Don't try to send hotplug events for virtual displays.
- Mark virtual displays as connected so HWComposer::prepare() doesn't
think something is wrong when it gets a non-NULL layer list.
- Remove unused FramebufferSurface methods.

This change adds support for tracing specific kernel function calls using the
function_graph tracer. It adds a '-k' option to atrace that accepts a comma
separated list of kernel function names for which tracing will be enabled.
