Makes a test mapping for statsd so that unit tests run on presubmit.
Changes to make the tests pass:
1. Require root. This is needed to write to disk, since the tests don't
run as statsd's uid
2. Remove AndroidTest.xml file in favor of the autogenerated one.
3. Remove a check in StatsService.test for getUidFromArgs. The test
checked a failure case where we passed a number bigger than INT32_MAX.
However, on a 32 bit device, strtol will return INT32_MAX when an
overflow happens, since it returns a 32 bit number on a 32 bit device.
4. Refactor a lot of e2e tests to sort dimensions, ensuring that the
dimensions are always in order, instead of relying on implicit ordering
of hashing, which can change.
5. Change a long to an int64 in TestActivationsPersistAcrossSystemServerRestart

Major changes include:
- Removing unused permission checks within StatsService. These
include ENFORCE_DUMP_AND_USAGE_STATS, checkDumpAndUsageStats,
kOpUsage, and kPermissionUsage.
- Converting from sp to shared_ptr
- Using libbinder_ndk functions instead of libbinder functions
(e.g. for installing death recipients, getting calling uids, etc.)
- New death recipients were added in StatsService,
ConfigManager, and SubscriberReporter.
- Using a unique token (timestamp) to identify shell subscribers
instead of IResultReceiver because IResultReceiver is not exposed by
libbinder_ndk. Currently, statsd cannot detect if perfd dies; we
will fix that later.

+ Create a thread-safe LogEventQueue to buffer log events.
+ The socket listner thread will read from socket and write to the buffer as quickly as possible
to minimize the data loss in socket.
+ All pushed data is fetched from the the buffer and processed in a dedicated thread. After an
event is fetched from the queue, we no longer block the socket listener thread.
+ Report event queue stats via statsdstats, including the min and max queue event history span in
the queue (to understand how slow statsd can be and how fast the events can be)

Test: unit tests added in statsd_test

Previously, most StatsService calls only allow the caller to specify the
uid if it is Userdebug/EngBuild. This applied even if the caller was
just specifying its own UID; this cl allows such a case. It also allows
ROOT to impersonate SHELL.
Test: Manual testing on userdebug and userbuild devices.
Test: make statsd_test && adb sync data && adb shell data/nativetest64/statsd_test/statsd_test

Statsd clients may want to set an empty config temporarily, so it's
more convenient to allow them to set an empty config instead of
having to use the removeConfig and then having to remember to call
StatsManager#setDataFetchOperation.
Test: Added unit-tests and check they pass on marlin-eng.
