This patch adds support for Win32 named pipes for the communication
channel between the Opengl renderer library and its clients.
Named pipes should be much faster than local TCP sockets on this
platform. Note that by default, TCP sockets are still used. The
emulator needs to call setStreamMode(STREAM_MODE_PIPE) to be able
to use these.

This patch allows the OpenGLES rendering library to use Unix
sockets instead of TCP ones when communicating with its clients.
On certain benchmarks (e.g. 0xBench teapot), this provides a
noticeable improvement (x1.05 fps) without any other changes.
On practice, Unix sockets are faster than TCP sockets, even
local ones. Also, this introduces a moderate amount of
abstraction that will allow us to use Win32 named pipes
on Windows (where TCP sockets are much slower than they
are on Unix).
Note that by default, TCP streams are still used.
The client (emulator) must call the new API 'setStreamMode'
to change it to STREAM_MODE_UNIX between 'initLibrary' and
'startOpenglRenderer' calls.
+ Adjust callers / user appropriately.

This re-enables the build of the gralloc GLES emulation library.
This is only for experimentation / debugging purpose. GLES emulation
is still disabled by default in the emulator. Even if you force-enable
it by using the '-gpu on' flag, this module will not properly yet
and nothing will be displayed.

The code submitted here builds a camera.goldfish.so module that encapsulates a camera HAL.
The major components of the camera HAL implementation are:
* Generic HAL module implemented in emulated_camera_hal.cpp There is nothing much
to it: just exporting the required HAL header.
* EmulatedCameraFactory class that manages emulated cameras, and provides handling for
camera_module_methods_ methods. There is only one object of this class, that is statically
instantiated when camera.goldfish.so module is loaded.
* EmulatedCamera class that implements camera_device_ops_t API. Objects of this class are
instantiated during EmulatedCameraFactory construction, and they interact with objects
of EmulatedCameraDevice class to get frames.
* EmulatedCameraDevice class encapsulates an actual camera device. Objects of this class
are contained in EmulatedCameraDevice objects, and interact with them as required by the
API.
The fake camera implementation is shared between EmulatedFakeCamera, and EmulatedFakeCameraDevice
classes. They are pretty light. In fact, EmulatedFakeCamera is nothing more than just a
placeholder for EmulatedFakeCameraDevice instance, and EmulatedFakeCameraDevice does nothing
more, than just drawing a checker board with a bouncing square.
Other components / routines are minor: helpers, wrappers, etc. The code is heavily commented,
so there will be plenty of explanations between the lines.

- moves tablet-style layouts to layout-large* directories
- adds ContentActivity to host the ContentFragment when on phones
- adds an OnItemSelectedListener interface to TitlesFragment, which MainActivity
implements in order to receive callbacks on click events to the list item and then
pass the selected item to the ContentFragment in the manner appropriate for the
current configuration... Specifically, when in two-pane mode, it updates the ContentFragment
directly, and when in single-pane mode, it starts the ContentActivity with intent data
about the selected item, which then updates the ContentFragment
- Change CameraSample.java to CameraActivity.java for name conventions
- Moves all menu strings into string resources
- Fixes camera sample to properly handle front-facing camera on other devices (was broken
on nexus s and on g-slate)
- Fixes camera sample to handle resume state after the camera has changed (for example, when
switched to a different camera, it would crash on resume)
- Moves various code around between classes as appropriate for the fragment handling the
action. For example, move the ActionBar.TabListener implementation to the TitlesFragment
(was originally impemented by the MainActivity)
- Adds logic to support devices without camera and properly declare the camera in manifest as such
- Maintains the state of hidden titles list across restarts

These templates were previously located in sdk.git but
are actually embedded in sdk/platforms/android-n/templates
so really they should be in development.git to avoid
any multi-repo issue.

This fixes the definition of the emulator-specific egl.cfg file
used to indicate to our EGL system library which support modules
are available in the emulator.
We need to list two modules here:
'emulation' corresponding to GPU emulation
'android' corresponding to the software renderer
The indices before each name correspond to the 'display' and 'impl'
numbers that are expected by frameworks/base/opengl/libs/EGL/Loader.cpp
In a nutshell, 'display' should always be 0, and 'impl' should be 0
for the software renderer, and 1 for a hardware-based one. See the code
under framewors/base/opengl/libs/EGL/egl.cpp for mode details.

The gralloc.goldfish module cannot build in master because
the gralloc interface evolved considerably since gingerbread
(which the current code is based on).
For now, disable it completely, this will make it impossible
to test GPU emulation in the internal master tree for now.
We'll have to port this module to the new world-order to solve
this.

This adds an initLibrary() function to libOpenglRender.
It will be used by the emulator to fallback on software rendering
if the library cannot be initialized properly, e.g. if it is not
possible to load the host EGL/GLES libraries.

This patch changes the filter used to scale the GL window
in the rendering library. Instead of nearest-neighbour, use
bi-linear, which will provide for much more pleasant results
when scaling the emulator UI window, or toggling to full-screen
mode.

This patch modifies the gralloc.goldfish module to check
that the emulator does, indeed, support GPU emulation.
If this is not the case, it loads the framebuffer-based fallback
module (gralloc.default) explicitely and uses it instead.
This is necessary because sometimes the emulator will be started
in headless mode in restricted environment, i.e. without access
to the display subsystem or GL libraries, which make GPU emulation
impossible.
We check for ro.kernel.qemu.gles which will be either undefined
or set to 0 if the emulator doesn't support GPU emulation, or 1
otherwise.
