I made the power manager more rigid, not allowing different uids
to use the same wake lock. This never should happen. I would
guess there is somewhere that the activity manager is acquiring
the wake lock without clearing the calling identity... but it is
hard to follow all the paths this may happen in. So here we add
some checks when acquiring/releasing the wake lock to make sure
it is being done as the system uid.
Also:
- Protect the new activity stack calls with a permission, and
make sure to clear the calling uid once past that.
- Collect uid data from process stats so we can correctly
associate CPU use with a uid even if we don't know about the
pid for some reason.
- Fix battery stats dump commands to clear calling uid before
executing so they aren't broken.

Completely reworked how it manages its data, since trying
to keep track of all of the possible pss data with the old
data structures would have made it huge. Now we have a sparse
data structure for pss and process times. (Will switch service
times over to it soon.)
Currently the only thing that collects pss data is running
"dumpsys meminfo". More will be added later.
Modified checkin output to also scale better as more distinct
data categories are added, and added output of pss data. Now
instead of dumping every possible entry as a comma-separated
list, it dumps a comma-separated list of only the entries with
data, tagged with the state they go with.
Also fixed some problems in the checkin reporting of batterystats
(it needs to escape commas), added checkin reporting of the history
list, fixed parsing of kernel wake locks to strip quotes, fixed
wake lock name that the sync manager generates to be more sane.

Introduces a new "blocked" state for each package. This is used to temporarily
disable an app via Settings->Restrictions.
PIN creation and challenge activities for use by Settings and other apps. PIN
is stored by the User Manager and it manages the interval for retry attempts
across reboots.

One problem this turned up is, because FastPrintWriter does
its own buffering, a lot of code that used to use PrintWriter
would fail -- if it pointed to a StringWriter, there was no
buffering, so it could just immediately get the result. Now
you need to first flush the FastPrintWriter.
Also added some new constructors to specify the size of buffer
that FastPrintWriter should use.

Re-arranged code to be more flexible, now track
state of services, dump ordered list of running

Also rename battery stats service from "batteryinfo" to "batterystats".

Every incoming Binder call ends up triggering a BlockGuardPolicy
update, which would thrash between new AndroidBlockGuardPolicy
instances and BlockGuard.LAX_POLICY, causing GC churn.
This change avoids the extra allocations by recycling a single
AndroidBlockGuardPolicy in a ThreadLocal. Worst-case thrashing case
is now 10% faster; from 7.46us to 6.65us.

Network stats are now read out of the kernel in one sweep, instead of
reading per-UID. We now accumulate the delta traffic between each
stats snapshot using the well-tested SamplingCounter pattern.
Since Wi-Fi and mobile traffic have different costs, track each
separately. Avoids counting misc interfaces like loopback and
ethernet under total.

Yay to ArrayMap, letting me get rid of a bunch of temporary
iterators in core code paths like updateOomAdj. (Now I definitely
need an ArraySet to finish that up.)
Also clean up various other things that are doing unnecessary
allocations, clean up some debug output, make more of the debug
output respect package filtering.

- Rename "Swappable PSS" to "PSS Clean" which I think is what it
means and is consistent with the other memory metrics.
- Split at the top level the dalvik heap from other dalvik allocations,
so when you look on the dalvik allocations line things are consistent
with the allocator's data and it is clear what are app allocations vs.
other data in dalvik.
- Don't print lines that are all 0.
- Don't print the detailed Dalvik allocation data by default; add a new
option to have it printed.
Here's what a typical system process dump now looks like:

If an app mistakenly puts some Parcelable implementation of
CharSequence in here, Bundle will try to marshal the derived
class, which is going to be bad news when we try to unparcel
it in another process.
Additionally add a proper stack trace to unparceling
failures (otherwise you have no idea where the bad parcel
was being used).

Adds an optimization for checking whether a looper is stuck,
with a new Looper method to see if its thread is currently
idle. This will allow us to put a large number of loopers
in the monitor efficiently, since we generally won't have to
do a context switch on each of them (since most looper threads
spend most of their time idle waiting for work).
Also change things so the system process's main thread
is actually running on the main thread. Because Jeff
asked for this, and who am I to argue? :)

Basic implementation of an undo manager. Supports
multi-level undo/redo, building on the top undo state
as edits occur, managing multiple distinct entities in
the undo state (such as embedded objects in a document),
and saving/restoring the full undo state. Still some
work remaining on correctly dealing with dependencies
between undo states that hold multiple owners.
Also do a simple implementation of undo state in TextView
to see how things actually work. The implementation here
is very primitive: it needs a lot more work to correctly
identify when to merge undo ops, is not trying to do
anything smart with style spans, etc.

IActivityController has a new callback which the Watchdog calls
when it detects that the system process is hung. This may be
use full monkey. All hail the monkey!
Also add a new private feature to Binder to be able to turn off
all incoming dump() calls to a process. The watchdog uses this
when it reports it is hung, so that if someone, say, wants to
collect a bug report at this point they won't get stuck waiting
for things that are all busted.
