This is needed when the parent or any other thread besides the child
needs access to the child's kernel tid.

66fbde3050 Add a basic hashtable data structure, with tests!
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.

18092ddc86 Change assets to use 64-bit API
The asset system and supporting libraries were using off_t instead of
off64_t to access files larger than 2GB (32-bit signed). This change
replaces all off_t with off64_t and lseek64.

There is a new utils/Compat.h added for Mac OS compatibility.

Also fixed some size-related compiler warnings.

6688837ff6 Support non-orientation aware keyboards and other devices.
Fixed a bug with dpad keys on external keyboards being rotated
according to the display orientation by adding a new input device
configuration property called "keyboard.orientationAware".

Added a mechanism for overriding the key layout and key character
map in the input device configuration file using the new
"keyboard.layout" and "keyboard.characterMap" properties.

Also added "trackball.orientationAware", "touch.orientationAware" and
"touch.deviceType" configuration properties.

Rewrote the configuration property reading code in native code
so that it can be used by EventHub and other components.

Added basic support for installable idc, kl, and kcm files
in /data/system/devices.  However, there is no provision for
copying files there yet.

Disabled long-press character pickers on full keyboards so that
key repeating works as expected.

a3477c862a Added support for full PC-style keyboards.
BREAKING CHANGE: Redesigned the key character map format to
accomodate full keyboards with more comprehensive suite of modifiers.
Old key character maps will not work anymore and must be updated.
The new format is plain text only and it not compiled to a binary
file (so the "kcm" tool will be removed in a subsequent check-in).

Added FULL keyboard type to support full PC-style keyboards.

Added SPECIAL_FUNCTION keyboard type to support special function
keypads that do not have any printable keys suitable for typing
and only have keys like HOME and POWER

Added a special VIRTUAL_KEYBOARD device id convention that maps
to a virtual keyboard with a fixed known layout.  This is designed
to work around issues injecting input events on devices whose
built-in keyboard does not have a useful key character map (ie.
when the built-in keyboard is a special function keyboard only.)

Modified several places where events were being synthesized
to use the virtual keyboard.

Removed support for the "qwerty" default layout.
The new default layout is "Generic".  For the most part "qwerty"
was being used as a backstop in case the built-in keyboard did
not have a key character map (probably because it was a special
function keypad) and the framework needed to be able to inject
key events anyways.  The latter issue is resolved by using the
special VIRTUAL_KEYBOARD device instead of BUILT_IN_KEYBOARD.

Added the concept of a key modifier behavior so that
MetaKeyKeyListener can distinguish between keyboards that use
chorded vs. toggled modifiers.

Wrote more robust key layout and key character map parsers
to enable support for new keyboard features and user installable
key maps.

Fixed a bug in InputReader generating key ups when keys
are released out of sequence.

Updated tons of documentation.

Currently QwertyKeyListener is being used for full keyboards
with autotext and capitalization disabled.  This mostly works
but causes some problems with character pickers, etc.
These issues will be resolved in subsequent changes.

59abe7e090 Replace epoll() with poll() and rename PollLoop to Looper.
As part of this change, consolidated and cleaned up the Looper API so
that there are fewer distinctions between the NDK and non-NDK declarations
(no need for two callback types, etc.).

Removed the dependence on specific constants from sys/poll.h such as
POLLIN.  Instead looper.h defines events like LOOPER_EVENT_INPUT for
the events that it supports.  That should help make any future
under-the-hood implementation changes easier.

Fixed a couple of compiler warnings along the way.

a45a8008c6 Support streaming of compressed assets > 1 megabyte
Compressed assets larger than one megabyte are now decompressed on demand
rather than being decompressed in their entirety and held in memory.  Reading
the data in order is relatively efficient, as is seeking forward in the stream.
Seeking backwards is supported, but requires reprocessing the compressed data
from the beginning, so is very inefficient.

In addition, the size limit on compressed assets has been eliminated.

e839a589bf Native input dispatch rewrite work in progress.
The old dispatch mechanism has been left in place and continues to
be used by default for now.  To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.

Includes part of the new input event NDK API.  Some details TBD.

To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument.  The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points.  The ViewRoot then
provides the InputChannel to the InputQueue.  Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue.  This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.

There can be zero or more targets for any given input event.  Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets).  Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.

End-to-end event dispatch mostly works!

To do: event injection, rate limiting, ANRs, testing, optimization, etc.

386a332b4f Make static versions of libutils and libbinder.
Fix some small static-initialization-order issues (and a static-
initializers-missing issue) that result from doing so.  The static
libraries don't actually get used for anything real at the moment --
they're used for perf tests of bug 2660235.

98e71ddaed remove a dependency of GraphicBuffer (libui) on Parcel (libbinder).
Add a Flattenable interface to libutils which can be used to flatten
an object into bytestream + filedescriptor stream.
Parcel is modified to handle Flattenable. And GraphicBuffer implements
Flattenable.

Except for the overlay classes libui is now independent of libbinder.
