EGL classes in frameworks/base have to be updated to support
64-bit platforms. Key changes in the EGL classes include
[x] EGLObjectHandle class - EGLObjectHandle class has two public
methods (constructor and getHandle) that assume handles are
32-bit. They have not been changed. Instead, two new hidden
methods (EGLObjectHandle(long) and getNativeHandle) have been
added.
[x] EG14 class - Two public methods eglGetDisplay and
eglCreatePbufferFromClientBuffer assume that handles are 32-bit.
They have been changed to throw unsupported operation exception
on non 32-bit machines. Two new methods eglGetDisplay(long)
and eglCreatePbufferFromClientBuffer(...long buffer..) have
been added to support 64-bit handles.
To allow the above changes in frameworks/base EGL classes,
corresponding code generation mechanism in frameworks/native has
been updated.

When using 64 bit binder pointers, only initializing the 32 bit
handle, in a stack allocated struct, will pass uninitialized stack
data to the kernel and other processes.

When using the 64 bit binder interface from a 32 bit process the

Support any number of overlay packages. Support any target package.
UPDATED PACKAGE MATCHING
------------------------
In Runtime resource overlay, iteration 1, only a single overlay package
was considered. Package matching was based on file paths:
/vendor/overlay/system/framework-res.apk corresponded to
/system/framework-res.apk. Introduce a more flexible matching scheme
where any package is an overlay package if its manifest includes
<overlay targetPackage="com.target.package"/>
For security reasons, an overlay package must fulfill certain criteria
to take effect: see below.
THE IDMAP TOOL AND IDMAP FILES
------------------------------
Idmap files are created by the 'idmap' binary; idmap files must be
present when loading packages. For the Android system, Zygote calls
'idmap' as part of the resource pre-loading. For application packages,
'idmap' is invoked via 'installd' during package installation (similar
to 'dexopt').
UPDATED FLOW
------------
The following is an outline of the start-up sequences for the Android
system and Android apps. Steps marked with '+' are introduced by this
commit.
Zygote initialization
Initial AssetManager object created
+ idmap --scan creates idmaps for overlays targeting 'android', \
stores list of overlays in /data/resource-cache/overlays.list
AssetManager caches framework-res.apk
+ AssetManager caches overlay packages listed in overlays.list
Android boot
New AssetManager's ResTable acquired
AssetManager re-uses cached framework-res.apk
+ AssetManager re-uses cached 'android' overlays (if any)
App boot
ActivityThread prepares AssetManager to load app.apk
+ ActivityThread prepares AssetManager to load app overlays (if any)
New AssetManager's ResTable acquired as per Android boot
SECURITY
--------
Overlay packages are required to be pre-loaded (in /vendor/overlay).
These packages are trusted by definition. A future iteration of runtime
resource overlay may add support for downloaded overlays, which would
likely require target and overlay signatures match for the overlay to
be trusted.
LOOKUP PRIORITY
---------------
During resource lookup, packages are sequentially queried to provide a
best match, given the constraints of the current configuration. If any
package provide a better match than what has been found so far, it
replaces the previous match. The target package is always queried last.
When loading a package with more than one overlay, the order in which
the overlays are added become significant if several packages overlay
the same resource.
Had downloaded overlays been supported, the install time could have been
used to determine the load order. Regardless, for pre-installed
overlays, the install time is randomly determined by the order in which
the Package Manager locates the packages during initial boot. To support
a well-defined order, pre-installed overlay packages are expected to
define an additional 'priority' attribute in their <overlay> tags:
<overlay targetPackage="com.target.package" priority="1234"/>
Pre-installed overlays are loaded in order of their priority attributes,
sorted in ascending order.
Assigning the same priority to several overlays targeting the same base
package leads to undefined behaviour. It is the responsibility of the
vendor to avoid this.
The following example shows the ResTable and PackageGroups after loading
an application and two overlays. The resource lookup framework will
query the packages in the order C, B, A.
+------+------+- -+------+------+
| 0x01 | | ... | | 0x7f |
+------+------+- -+------+------+
| |
"android" Target package A
|
Pre-installed overlay B (priority 1)
|
Pre-installed overlay C (priority 2)

Introduce a new tool 'idmap' to handle generation and verification of
idmap files. The tool is modelled on 'dexopt', and is intended to be
used similarly, notably by 'installd'.
See cmds/idmap/idmap.cpp for further documentation on 'idmap'.
Note: this commit is interdependent on a commit in project build/ to add
'idmap' to PRODUCT_PACKAGES.
Note: the changes to androidfw are only stubs. The actual implementation
will be provided in Runtime resource overlay, iteration 2.

Changes include
- Binder attempts to cast pointers to a int datatype
which is not sufficient on a 64-bit platform.
- This patch introduces new read/write functions into
Parcel that allow pointers to be written using the
uintptr_t datatype for compile-time data type size
selection.
- Change access specifier for the methods above.
- Binder uses the 64bit android_atomic_release_cas64
(aka cmpxchg)
