This commit makes the LocaleList constructor require non-null
arguments in all cases, and fixes all uses of LocaleList that could
previously pass a null to use getEmptyLocaleList() instead (which is
preferred anyway becaues it avoids an allocation.

-- Remove default constructor from public API since getEmptyLocaleList exists
-- Merge the Locale and Locale[] constructors by providing a single Locale… varargs constructor
-- forLanguageTags, get, toLanguageTags, size, need docs

We used the system proterties as a shared memory mechanism
to propagate information to local settings caches when the
content has changed and the cache should be cleared. The
system properties are unfortunately updated asynchronously
leading to cases where clients may read stale data.
This change adds a simple int array data structure backed
by shared memory which guarantees individual values are
atomically read and updated without memory tear. Multi-
index opearations are not synchronized between each other.
The settings provider is using the new data structure to
propagate the settings generation which drives when caches
are purged.
We have a single memory array keeping the generation for
different settings tables per user. Since memory array is
not a compact data structure and the user space exceeds
the memory array size we use an in-memory map from keys
to indices in the memory array where the generation id of
a key is stored. A key is derived by the setting type in
the 4 most significant bits and the user id in the 28 least
significant bits.
The mapping from a key to an index is cleared if the user is
removed and the corresponding index in the memory arry is
reset to make it available for other users. The size of the
memory array is derived from the max user count that can be
created at the same time.

The current build process may currently strip APK Signature Scheme v2
signatures from prebuilt APKs to be installed on the system or vendor
partitions. However, it leaves intact the signature scheme rollback
protections introduced by APK Signature Scheme v2. Due to a bug, when
the system extracts signer certificates from preinstalled APKs, it
encounters the rollback protection and aborts the extraction process.
This manifests itself as some preinstalled packages not appearing as
installed.
This change makes the system ignore signature scheme rollback
protections when extracting certificates from preinstalled APKs. This
is fine because the process of extracting certificates from
preinstalled APKs does not care about validity/integrity of signatures
and the APKs. It only cares about extracting signer certificates.

The original implementation of APK Signature Scheme v2 verification
mmapped the whole APK. This does not work on devices with limited
amount of contiguous free logical memory, especially on 32-bit
devices where logical address space is relatively small. For example,
a 500 MB APK is unlikely to mmap on a Nexus 6.
This commit fixes the issue by switching the verification strategy
to mmapping each individual 1 MB chunk of the APK, digesting it, and
then immediately munmapping. This is about 5-10% slower than mmapping
the whole APK in one go.

When an APK is verifier during installation, the recently added
APK Signature Scheme v2 code uncondionally memory-maps the whole file.
This fails for very large APKs, even those which are not signed with
APK Signature Scheme, thus preventing installation of such APKs.
This temporary workaround pretends that the APK is not signed with
APK Signature Scheme v2 if the APK cannot be memory-mapped because
there's insufficient memory.
This workaround will be removed soon, once APK Signature Scheme v2
APK verification logic can handle very large APKs.

This change adds a new LockGuard utility class that can be used to
detect lock inversions across the system server. For example, if a
thread is trying to acquire the ActivityManager lock while holding the
PackageManager lock, it will yell.
This class requires no prior knowledge of locks or their ordering; it
derives all of this data at runtime. However, this means the overhead
is substantial and it should not be enabled by default.
Adds overrides to ArrayMap and ArraySet to use identityHashCode()
instead of the hashCode() provided by the object.

Similar to first patch, but now using new "rethrowFromSystemServer()"

- Remove the LocaleList#getPrimary() API. It had become confusing
after locale negotiation was completely implemented. For example,
it could create the confusion that calling getPrimary() on the
default locale list would provide the default locale, etc.
- Use the adjusted locale list from LocaleList.getAdjustedDefault()
in Paints created with no locale list provided.
- Change LocaleList#get() to treat out of bound indexes from both
negative indexes and too large indexes the same way.

Previously, locale resolution happened at Resources level, which
could result in different Resources in the same app using different
locales.
This change moves the locale negotiation to ResourcesManager, which
remembers the locales supported by each Resources as they are
created, and negotiates the locale based on their union.
It also makes sure that the old model of apps getting the default
locale by accessing it through the Configuration's locale attribute
continues to work, since the negotiated locale will be moved to the
top of the list before Resources are created and when they are
updated with a Configuration change.

This makes Package Manager check whether an APK is signed using APK
Signature Scheme v2 and, if it is, verify the APK's signatures using
that scheme rather than the usual JAR signature scheme.
APK Signature Scheme v2 is a whole-file signature scheme which aims
to protect every single bit of the APK as opposed to the JAR signature
scheme which protects only the names and uncompressed contents of ZIP
entries.
The two main goals of APK Signature Scheme v2 are:
1. Detect any unauthorized modifications to the APK. This is achieved
by making the signature cover every byte of the APK being signed.
2. Enable much faster signature and integrity verification. This is
achieved by requiring only a minimal amount of APK parsing before
the signature is verified, thus completely bypassing ZIP entry
decompression and by making integrity verification parallelizable
by employing a hash tree.

Two setters are added, a hidden one for fast unsafe calls when the
input is known to be OK, and a public one for normal users.
A hidden constructor is also added for adjusting locale lists and
moving a locale to the front.
Finally, an indexOf method is added. It's only used in testing now,
but it's potentially useful for others too.

In practice, a lot of apps provide English resources as their default
resources, so assume that English is always supported.
With this change, users can safely set secondary locales after
English in their preferred locale lists. Such settings would help
the apps (and parts of the system that are aware of multiple locales)
consider the user's familiarity with the secondary locale or the
user's preference for glyphs forms in the secondary locale. This
change makes sure that no app unintentionally switches to such
secondary locales.
Note that this doesn't break from the tradition of previous releases.
Traditionally, if the user had set the system locale to English, they
would get the default resources when the app didn't explicitly
provide English resources. This will continue to be the case where
the user's locale list has English in it before another supported
language. (English will be the first locale in most cases.)

The suggested TODO is no longer deemed necessary (and is too
expensive to do for all LocaleLists). LocaleLists get (and will get)
passed down to the native level through strings that are the result
of calls to toLanguageTags(), which is pre-computed at construction
time. Users who need to interact with the native level can do their
own caching, such as in commit
cfc607cf57.

Introduced a new regular expression to autolink URLs. Previous regular
expression used the protocol as an optional rule. The new expression
applies separate rules for strings that do not start with a known
protocol and strings that do start with a known protocol.
- In order to reuse previous regular expression definitions for
different parts of a URL, created constants for different parts of
WEB_URL expression.
- Separated the test cases for WEB_URL in order to remove the suppress
command and make them running again.
- Fixed failing tests for punycode urls, which were causing existing
tests to fail.
- Introduced new a regular expression for URL matching.
- Changed the protocol rule to be case insensitive.
- Updated IANA TLDs.
- Added tests for the new regular expression.
- Added tests for Linkify.
- Bug 9622849 is partially fixed.
