The base APK may have resources with configurations that compete
against some splits. The base APK must be involved in the selection
of splits.

We'd observed a bug in which an unchanged file was nevertheless
being redundantly transmitted for backup on every backup pass.
The underlying issue turns out to have been the FileBackupHelper
base implementation's logic for diffing the prior-state file
set against the current state, in the case when there had been
deletions of prior files. In addition, there was also a
parallel bug in which file checksums were not calculated
properly in some cases, leading to at least one additional
redundant backup of the file in question.

A sentinal value of 0x00000000 was used to mark the first time an AttributeFinder
was used. If the resource ID of an attribute was also 0x00000000 (which occurs with
non-resource attributes, like 'style'), then it would be mistaken as the sentinel
start value.

Private attributes are typically placed after public
attributes in the resource table. Each time a new version
of the Android framework is released, new public attributes
take the place of the private attributes, and the private
attributes are shifted after the new public ones.
This means that any apps built against the newer SDK
may inadvertently be using private attributes on older
devices.
This change moves all private attributes to a completely
different type ID, so there will never be collisions across
versions.
These private attributes are automatically moved to a synthesized
type only for the system resources.

Shared libraries have their package ID assigned at run-time, so some
of the guarantees we used to have about sort order of attributes in
bags or XML elements no longer hold.
This CL adds back-tracking and can jump to the nearest attribute with the
same package ID and continue searching.
This means that attributes with the same package ID must be sorted by increasing
resource ID, as was the case before.
Attributes with the same package ID must be grouped together, but the groups can
be in any order. Ex: 0x02010001, 0x02010002, 0x01010000, 0x01010010, 0x7f010032

- char16_t is a distinct type, so stay consistent
with it throughout the code base.
- char16_t is defined as minimum size of 16 bits.
Since we mmap and cast data structures onto raw memory,
we need a precise definition (uint16_t), so we cast between
that (and static_assert that they are the same size).

AAPT has traditionally assigned resource IDs to public attributes,
and then followed those public definitions with private attributes.
--- PUBLIC ---
| 0x01010234 | attr/color
| 0x01010235 | attr/background
--- PRIVATE ---
| 0x01010236 | attr/secret
| 0x01010237 | attr/shhh
Each release, when attributes are added, they take the place of the private
attributes and the private attributes are shifted down again.
--- PUBLIC ---
| 0x01010234 | attr/color
| 0x01010235 | attr/background
| 0x01010236 | attr/shinyNewAttr
| 0x01010237 | attr/highlyValuedFeature
--- PRIVATE ---
| 0x01010238 | attr/secret
| 0x01010239 | attr/shhh
Platform code may look for private attributes set in a theme. If an app
compiled against a newer version of the platform uses a new public
attribute that happens to have the same ID as the private attribute
the older platform is expecting, then the behavior is undefined.
We get around this by detecting any newly defined attributes (in L),
copy the resource into a -v21 qualified resource, and delete the
attribute from the original resource. This ensures that older platforms
don't see the new attribute, but when running on L+ platforms, the
attribute will be respected.
We still need to address this problem in the platform moving forward,
as this will only help us in the transition from pre L to L.

When Android processes fork from Zygote, we rewrite the command line
with a new name, eg. "system_server". When we do this, we should
fill the entire block with zeros to remove corrupted argument
information that may otherwise remain in the /proc/<pid>/cmdline buffer
and be seen in tools and stack dumps.
Fixed an issue where VM options could be overwritten after setting
the nice name if the name was too long.

The versionCode of theframework resources that an app is built against
gets stamped inside an app's AndroidManifest.xml in the <manifest>
tag as "platformBuildVersionCode" and "platformBuildVersionName"
attributes.

This is meant to be used with scaleable vector
drawables, and are chosen as the best match unless
there is a configuration that matches the density
requested exactly.

This change allows the developer to add a base package for
which to build a feature split. The generated resource types
will begin after the base APK's defined types so as not
to collide or override resources.
Multiple features can be generated by first choosing an
arbitrary order for the features. Then for each feature,
the base APK and any preceding features are specified
with the --feature-of flags.
So with a base APK 'A' and features, 'B', and 'C',
'B' would be built with
aapt package [...] --feature-of A [...]
and 'C' would be built with
aapt package [...] --feature-of A --feature-of B [...]

This will allow us to conditionally change the compiler-filter based on other properties.

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.

- 3 letter codes are packed into the existing 32 bit locale
field in ResTable_config
- 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
specific than those without.
