Refactor ProcessStats.
- Pull most of the inner classes out into their own files.
- Move everything to a new android.app.procstats package.
- Move all of the code that was manipulating the big list
of longs to use the new SparseMappingTable class rather
than doing everything by hand. The logic is unchanged.
- Add a sequence number check to SparseMappingTable so
when the big list of longs and the individual tables are
reset, which happens somewhat independently, we can
assert when one of them doesn't get reset.

Work on issue #18640385: Add procstats test mode
You can now do "adb shell dumpsys procstats --start-testing" to
enable high frequency pss sampling.
Also improved the low on RAM mem reporting to separate out RAM
from memtrack, in case the data we are getting from that is bad.
And fixed meminfo --oom to work correctly again.

Work on issue #18486438: Reduce size of bugreport output
Reduce how much stuff ProcessStats spews, and do collapsing of
repeated intent filter targets when dumping IntentResolvers.
Also add to pm's checkout output to include shared user ids,
and fix output formatting in a few places.

Avoid deadlock between ActivityManagerService and ProcessStatsService.
Root Cause:
Case 1
getStatsOverTime(#483) // lock mWriteLock, wait AMS
async performWriteState(#269) // lock mPendingWriteLock, wait mWriteLock
writeStateLocked(#218) // lock AMS, wait mPendingWriteLock
Case 2
getStatsOverTime(#483) // lock mWriteLock, wait AMS
writeStateSyncLocked,writeStateLocked(#269) // lock AMS, wait mWriteLock
Solution:
Reduce nested lock.
Others also post the same solution:

Improve some docs, fix some debugging.
- Add docs to Binder, Messenger, ResultReceier to explain their
relation (or lack there-of) to process lifecycle.
- Clarify some aspects of process lifecycle for services.
- Fix help text of am command.
- Fix per-package dumping of battery stats to not include history.
- Fix per-package dumping of proc stats to only include aggregated
and current stats and fix some formatting.
- Fix per-process dumping of meminfo to have an option to interpret
the input as a package, so including all processes that are
running code of that package.
- Fix top-level per-package debug output to correctly include all
of these improvements and give them a little more time (10s) to
complete for timing out.

Maybe fix issue #17614177 APR: system process restarting due to infinite loop
Also try to get rid of a huge wtf we are seeing across a lot of devices
where we incorrectly change real states on a service that is restarting,
and get rid of one of the noisier boot logs in the package manager.

Add kernel and native memory data to procstats.
We now collect memory use data in the kernel and native
application for aggregation in procstats. This should
allows us to do aggregated summaries of how memory use
is distributed across the system -- how much is free vs.
how much is in use.
Fix a bug in how we were tracking per-app version codes:
apps that used a shared user id to have multiple packages
run in the same process could get their version codes
cross-wired. Now we keep track of version codes in the
list of packages associated with a process.
Bumped the checkin version code to 5, so that we can
distinguish checkins that have this corrected data.
Also fix a bug in battery stats monitoring radio state.

Add app version codes to procstats.
Now the per-package proc stats data is also per-app-version-code.
In addition to changing the data structure to have one more
SparseArray and passing a version code all over, this also required
improving how we reset the stats so that we can prune a multi-package
process record back to a single package. Otherwise, as you install
updates to apps, the proc stats data would continue to explode as
the data for each of those app's processes got turned to a
multi-package due to tracking the old and new versions at the
same time.
This also bumps the checkin version code, since the package entries
also include a new field for the app version code.

Move some system services to separate directories
Refactored the directory structure so that services can be optionally
excluded. This is step 1. Will be followed by another change that makes
it possible to remove services from the build.
