this means they only have access to the consumer end of
the interface. we had a lot of code that assumed consumers
where holding a BufferQueue (i.e.: both ends), so most of
this change is untangling in fix that

While currently untested, this should allow to move the
BuffereQueue in the consumer process and have everything
work as usual.

If there are two or more buffers pending that are ready for
immediate presentation, drop all but the last one.
Any code that didn't explicitly specify timestamps for buffers
was using the default value (auto-generated "now"). As a result,
surfaceflinger would drop frames whenever more than one buffer
was queued. We now use zero as the auto-generated timestamp,
and we don't set the timestamp in eglBeginFrame().

Fallout from the Flattenable change, update all its uses.
Additionnaly, fix/tighten size checks when (un)flatten()ing
things.
Removed the assumption by some flattenables (e.g.: Fence)
that the size passed to them would be exact (it can
and will be larger in some cases)
The code in Parcel is a bit complicated so that we don't
have to expose the full implementation (and also to
keep the code smallish).

Making an object Flattenable doesn't force it to
become virtual anymore. For instance, Fence and GraphicBuffer
are now non-virtual classes.
Also change Flatennable protocol a bit so that it updates
its parameters (pointers, sizes) to make it easier
to implement a flattenable in terms of other flattenables.

BufferQueue::dequeueBuffer() could incorrectly return
WOULD_BLOCK while in "cannot block" mode if it happened
while a consumer acquired the last allowed buffer
before releasing the old one (which is a valid thing
to do).

BuffferQueue disconnect is now always asynchrnous
BufferQueue improvements and APIs changes
we can now queue/dequeue a buffer in asynchrnous mode by using the
async parameter to these calls. async mode is only specified
with those calls (it is not modal anymore).
as a consequence it can only be specified when the buffer count
is not overidden, as error is returned otherwise.

we tag queued buffers with the "bufferqueue cannot block" flag
and use that bit to discard a buffer in the queue by new ones
comming in. this allows us to remove the buffer queue drain in
disconnect while maintaining the right behaviour if it gets
connected again (since each buffer remembers how it was enqueued).

this is the first step of a series of improvements to
BufferQueue. A few things happen in this change:
- setSynchronousMode() goes away as well as the SynchronousModeAllowed flag
- BufferQueue now defaults to (what used to be) synchronous mode
- a new "controlled by app" flag is passed when creating consumers and producers
those flags are used to put the BufferQueue in a mode where it
will never block if both flags are set. This is achieved by:
- returning an error from dequeueBuffer() if it would block
- making sure a buffer is always available by replacing
the previous buffer with the new one in queueBuffer()
(note: this is similar to what asynchrnous mode used to be)
Note: in this change EGL's swap-interval 0 is broken; this will be
fixed in another change.

When acquiring a buffer, SurfaceFlinger now computes the expected
presentation time and passes it to the BufferQueue acquireBuffer()
method. If it's not yet time to display the buffer, acquireBuffer()
returns PRESENT_LATER instead of a buffer.
The current implementation of the expected-present-time computation
uses approximations and guesswork.

Now that we are having separate buffer-instances for the buffer-

alive.

Instead of representing the buffer-queue as a vector of buffer
indices, represent them as a vector of BufferItems (copies).
This allows modifying the buffer slots independent of the queued
buffers.
As part of this change, BufferSlot properties that are only
been relevant in the buffer-queue have been removed.
Also, invalid scalingMode in queueBuffer now returns an error.
ConsumerBase has also changed to allow reuse of the same
buffer slots by different buffers.

until now it was only used to discard a layer entirely.
we're now reducing the size of the layer if it is still
visible, if possible.
this works for instance when a surfaceView is used and
only the menu bar is displayed over it.

when libutils is statically linked, the ordering of the static
initializer is not guaranteed and therefore it's unsafe to use
empty static strings: e.g.:
static String8 sThisStaticStringIsNotSafe;
instead, this new constructor can be used:
static String8 sThisStaticStringIsSafe(kEmptyString);
