In order to support APK split features, the resource
table needs to support loading multiple resource
tables with the same package but potentially new set
of type IDs.
This adds some complexity as the type ID space changes
from dense and ordered to potentially sparse.
A ByteBucketArray is used to store the type IDs in
a memory efficient way that allows for fast retrieval.
In addition, the IDMAP format has changed. We no longer
need random access to the type data, since we store the
types differently. However, random access to entries of
a given type is still required.

- Make copies of argc, argv before argv is potentially
overwritten with the process name.
- Allow multiple command line arguments to be passed to
ZygoteInit (this is required for some of the 64 bit
zygote work).
- Add an explanatory comment about how these argments
are processed.

These look like historical oddities, and weren't really being
used for anything useful.
Process:setArgV0 was being called by android.util.Process, but
that functionality can be moved directly into the implementation
of that class.

Shared libraries can now export resources for applications
to use.
Exporting resources works the same way the framework exports
resources, by defining the public symbols in res/values/public.xml.
Building a shared library requires aapt to be invoked with the
--shared-lib option. Shared libraries will be assigned a package
ID of 0x00 at build-time. At runtime, all loaded shared libraries
will be assigned a new package ID.
Currently, shared libraries should not import other shared libraries,
as those dependencies will not be loaded at runtime.
At runtime, reflection is used to update the package ID of resource
symbols in the shared library's R class file. The package name of
the R class file is assumed to be the same as the shared library's
package name declared in its manifest. This will be customizable in
a future commit.
See /tests/SharedLibrary/ for examples of a shared library and its
client.

The Res_png_9patch struct had several pointer members
whose size differed between 32 and 64 bit platforms.
These members have been replaced by uint32_t offsets
to serialized data. The serialized form for 9patches
places a Res_png_9patch object at the beginning of
serialized data, followed by int32_t arrays of xDivs,
yDivs and colors.
Note that these offsets are not strictly required,
since they can be computed from the values of numXDivs,
numYDivs & numColors, however they are called in tight
loops so having them computed once is a beneficial.
This change also removed the unused patch_equals function
from aapt's Image.cpp.

Support 3 letter language codes, script codes &
variants. The bulk of the changes are related to
the implementation of command line filtering of
locales etc. The previous code assumed that the
value of each "axis" (locale, density, size etc.)
could be represented by a 4 byte type. This is
no longer the case.
This change introduces a new class, AaptLocaleValue
which holds a (normalized) locale parsed from a
directory name or a filter string. This class takes
responsibility for parsing locales as well as
writing them to ResTable_config structures, which is
their representation in the resource table.
This includes minor changes at the java / JNI level
for AssetManager. We now call locale.toLanguageTag()
to give the native layer a well formed BCP-47 tag.
I've removed some duplicated parsing code in
AssetManager.cpp and replaced them with functions on
ResTable_config. The native getLocales function has
been changed to return well formed BCP-47 locales as
well, so that the corresponding java function can use
Locale.forLanguageTag to construct a Locale object
out of it.
Finally, this change introduces default and copy
constructors for ResTable_config to prevent having
to memset() the associated memory to 0 on every
stack allocation.

- We introduce new fields for script / variant information.
Note that we define a "match" between two ResTable_config
structures to be purely on the basis of their language &
country (disregarding the script and the variant). However,
configs with scripts and variants are considered to be more

Remove all of the pieces except the PointerController and SpriteController over
to frameworks/native in preparation for inputflinger. Those two need to stay in
frameworks/base for now because they depend on Skia currently. In the long run
they should be merged into either the InputManager or the WindowManager rather
than as a part of the inputservice / inputflinger.

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.
