Instead of sending finished signals immediately when appending to
a batch, record the chain of sequence numbers that were part of
the batch and then send finished signals all at once when done.
This change helps the dispatcher keep track of the true state
of the application and can improve ANR detection slightly.
This is part of a series of changes to improve input system pipelining.

To support this feature, the input dispatcher now allows input
events to be acknowledged out-of-order. As a result, the
consumer can choose to defer handling an input event from one
device (because it is building a big batch) while continuing
to handle input events from other devices.
The InputEventReceiver now sends a notification when a batch
is pending. The ViewRoot handles this notification by scheduling
a draw on the next sync. When the draw happens, the InputEventReceiver
is instructed to consume all pending batched input events, the
input event queue is fully processed (as much as possible),
and then the ViewRoot performs traversals as usual.
With these changes in place, the input dispatch latency is
consistently less than one frame as long as the application itself
isn't stalled. Input events are delivered to the application
as soon as possible and are handled as soon as possible. In practice,
it is no longer possible for an application to build up a huge
backlog of touch events.
This is part of a series of changes to improve input system pipelining.

Since we will not longer be modifying events in place, we don't need
to use an ashmem region for input. Simplified the code to instead
use a socket of type SOCK_SEQPACKET.

Services now must explicitly opt in to being accessed by isolated
processes. Currently only the activity manager and surface flinger
allow this. Activity manager is needed so that we can actually
bring up the process; SurfaceFlinger is needed to be able to get the
display information for creating the Configuration. The SurfaceFlinger
should be safe because the app doesn't have access to the window
manager so can't actually get a surface to do anything with.
The activity manager now protects most of its entry points against
isolated processes.

This adds basic support for clip regions. It is currently disabled at compile
time. Enabling clip regions will require setting up a stencil buffer.

with this changes, SF transactions are handled as soon as possible
but do not trigger updates. the update is delayed until the next
vsync.
this allows us to work much better without requiring triple-buffering.

vsync events were sometimes delivered to connected
client who didn't request them. this happened if
another client requested the delivery and that client
was first in the client list.
also fix the vsync test which didn't request any events as
well as DisplayEventReveiver documentation which was misleading
about the necessity to request vsync events.

In our current environment with very many translations, this can
save a lot of RAM -- for example over 200K in Gmail just by sorting
the strings in the Gmail .apk (not the framework).
Also add a new aapt command to print the contents of the resource
table string pool.

The idea is that this is a device which is more-or-less headless. It
might have some limited interaction capabilities, but it's not something
that you want to rely on having.

- add the ability to set the vsync delivery rate, when the rate is
set to N>1 (ie: receive every N vsync), SF process' is woken up for
all of vsync, but clients only see the every N events.
- add the concept of one-shot vsync events, with a call-back
to request the next one. currently the call-back is a binder IPC.

use gui/DisplayEvent to receive the events. Events are
dispatched through a unix pipe, so the API is compatible

Improved quick launch bookmarks to support category-based shortcuts
instead of hardcoding package and class names for all apps.
Added a set of Intent categories for typical applications on the
platform.
Added support for some of the HID application launch usages to
reduce reliance on quick launch for special purpose keys. Some
keyboard vendors have hardcoded launch keys that synthesize
"Search + X" type key combos. The goal is to encourage them
to stop doing this by implementing more of HID.

The basic hashtable is intended to be used to support a variety
of different datastructures such as map, set, multimap,
multiset, linkedmap, generationcache, etc.
Consequently its interface is fairly primitive.
The basic hashtable supports copy-on-write style functionality
using SharedBuffer.
The change introduces a simple generic function in TypeHelpers for
specifying hash functions. The idea is to add template
specializations of hash_type<T> next to the relevant data structures
such as String8, String16, sp<T>, etc.

* commit 'c25972950c2ea62fb085524dbe737c2bf0f08f4a':
SurfaceTexture: fix a couple tests
EGL: default to swap interval 1
SurfaceTexture: clean up some tests
This change makes SurfaceMediaSource add the VIDEO_ENC usage bit when
allocating its GraphicBuffers rather than the HW_TEXTURE bit.
