This doesn't alter the alignment of the data within the struct, but
enforces that this structure will be appropriately aligned when used.
The image_info struct has this struct preceded by a bool, which causes
odd alignment for the members of this struct.

Was here because UBsan found integer overflow in the parsing for hex
numbers, since hex numbers here are actually unsigned but assigned to
a signed integer.
Also fixes a number of missing error conditions.

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.

System overlays, ie overlays with targetPackage="android", were loaded
twice, which caused all sorts of issues. Ensure they are only loaded
once, which will be during Zygote initialization.

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.

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 [...]
