this is the first step in unifying surfacetexture and surface.
for this reason the header files were not moved, as most of them
will eventually go away.
NOTE: currently we keep libsurfaceflinger_client.so as an empty
library to workaround prebuilt binaries wrongly linking against
it.

- use Harfbuzz shaper for shaping and getting glyphs
- add test app for showing result of drawText() and drawGlyphs()
- add private API in Canvas and Paint for test app

Like getTransformMatrix, getTimestamp provides a timestamp for the
OpenGL texture produced by the latest call to updateTexImage().
Timestamps are measured in nanoseconds, and are monotonically
increasing. Other properties of the timestamps (zero point,
comparability) depend on the source providing frames to the
SurfaceTexture, and need to be documented by the source.

API addition: The timestamps are represented as nanoseconds from some
arbitrary time point. Like the SurfaceTexture transform matrix, the
timestamp retrieved by getTimestamp is for the last frame sent to the
GL texture using updateTexImage().
Camera HAL change: Expect vendors to set these timestamps using
native_window_set_buffers_timestamp(). For now, they are
autogenerated by SurfaceTextureClient if set_buffers_timestamp() is
never called, but such timing is likely not accurate enough to pass a
CTS test.

This change adds additional documentation explaining how a
SurfaceTexture should be used in OpenGL ES. It describes some of the
limitations of using the GL_TEXTURE_EXTERNAL_OES texture target.

This change enables the use of a SurfaceTexture in place of a Surface
as the video sink for an android.media.MediaPlayer. The new API
MediaPlayer.setTexture is currently hidden.
This includes:
- New Java and C++ interfaces
- C++ plumbing and implementation (JNI, Binder)
- Stagefright AwesomePlayer and NuPlayer use ANativeWindow
(either Surface or SurfaceTextureClient)

The JavaDoc says that if the "...count is negative then the
characters before index are measured in reverse order. This
allows for measuring the end of string."
However, the native code doesn't work its way backwards
from the given index when the count is negative. It always
passes Skia the substring starting from index and the
absolute value of count.
Its better to fix the JavaDoc rather than the behavior, since
this API is public and has been this way for some time. It
is also used by TextUtils.ellipsize indirectly, so its best
to avoid breaking that sensitive code.

It looks awful.
Don't use it.
Use ARGB_8888, it's much better.
If you think you need ARGB_4444, you are wrong.
You are.

Bug #3408073
Bitmap.setHasAlpha() in particular is very useful for applications that use
ARGB_8888 bitmaps but want/need to benefit from an extra speed boost.

Bug 3331706
The temporary buffer starts at index 0 and shifts indexes by contextStart.
offset has to be changed accordingly.
Note that I didn't try to reproduce the monkey bug after this fix, but it
seems like a perfect explanation for the exception.
