When statsd is told that it is time to poll data, it asks
StatsCompanionService to pull kernel wakelock data, receives the result
(as a string), and outputs it to screen.
Still to do:
1. don't use a string; use a parcel instead
2. don't output it to screen; do something useful instead
3. do more than just kernel wakelocks
4. pull data on demand, in addition to just on periodic pulling
Test: added setPollingAlarms to statsd.main and confirmed that kernel
wakelock information was written to screen

If statsd or statsdcompanion crashes, or if one loads
before the other, the other will be able to accomodate.
When statsd loads, it will attempt to tell statscompanion that it's
alive, and then get on to its business, while assuming that
statscompanion is not alive. Only when statscompanion tells statsd
that it is alive, statsd will then start to use it.
When statscompanion loads, it will attempt to tell statsd that it's
alive and then do nothing (since it has nothing to do). When statsd
tells statscompanion that statsd is alive, statscompanion will respond,
telling statsd that it is alive and, if that binder call returns, will
get to work.
This way, if statsd loads first, it can work unobstructed until
statscompanion informs statsd that it is alive, at which point they
shake hands and work. Conversely, if statscompanion loads first, it will
do nothing until statsd contacts it, at which point they will shake
hands and work.

Now that we're using Binder, we can have callers provide explicit
listeners for every request instead of trying to squeeze them all
into unsolicited socket events.
Move benchmarking to be async to avoid blocking other commands for
up to several minutes. Remove post-trim benchmarking flag, since
benchmarking now requires a separate callback. Will bring back in
a future CL.

Before this change, ZygoteProcess.preloadPackageForAbi returned
as soon as the command was written to the zygote socket and not
after the preload completed. This meant that there was a small
window of time before the server side of the socket polled its FDs
where a second command could be written to the zygote socket. This
would lead to only one of the commands being processed and the
other being dropped. The client side of that socket would then wait
forever for a response and bring down the system once the watchdog
timeout was hit.
Example failure case :
--------------
system_server：send command(preloadPackage)
system_server：send command(fork)
zygote：poll & process command(preloadPackage) // the fork command is dropped.
Example of normal operation :
------------------
system_server：send command(preloadPackage)
zygote：poll & process command(preloadPackage)
system_server：send command(fork)
zygote：poll & process command(fork)
This change makes preloadPackageForAbi synchronous, which ensures
that each POLLIN event corresponds to precisely one command.

RPM = resource power manager.
Fetching the rpm stats (specifically, the subsystem low power stats) is
slow... too slow to reasonably do each time the screen state changes.
Therefore, it is disabled until fetching this information can be done
more quickly. Consequently, the screen-off RPM values will be incorrect
until it is re-enabled; they are therefore not printed.

Currently Resource Power Management (e.g. VMIN time) is reported in the
batterystats history each time the battery level changes. We need this
information in the batterystats checkin, and need to be able to
differentiate time spent in each power state/voter, total as well as
when the screen is off.
The RPM information is obtained via a JNI call to the appropriate HALs.
Batterystats report version is increased to 26.

Introduces StatsCompanionService.java and sets it up as a system service.
This service is a helper for statsd. It will be responsible for setting
and cancelling alarms related to polling stats and anomaly detection.
It currently does not have selinux permission, so must be started
manually (or with selinux temporarily disabled).
Test: disable enforcing selinux, then set and cancel alarms and make
sure they work.
