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.

Bug #9191438
When running under valgrind, the ppid will be different from the ppid
of the system server (which always gets forked from zygote.)

- 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:

Added support for teasing apart different parts of the dalvik heap.
Note this adds more public api and we should talk to hackbod before going into master with this.

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.

To help correlate battery usage against actual foreground app usage,
start tracking time on a per UID basis. It uses the nesting feature
of StopwatchTimer to track multiple PIDs inside the same UID.
Improves units on docs, and persists foreground CPU time with a
consistent ordering. Reports foreground activities time and
foreground CPU time.

warnings.

It seems some applications rely on Looper.quit() terminating the
loop immediately without processing all messages. Rather than
risk breaking them, make the safer behavior optional.
Also take care to properly drain the message queue before quitting
so that all of the Message instances are recycled. This may
help release storage sooner in case the Looper doesn't get GC'd
promptly and its remaining queue of undelivered messages sticks
around.
Improve docs on runWithScissors.

Use a Bundle for persisting and passing to the application, but use a
list to return data back from an application that's exposing restrictions.
Changed the xml reading/writing code to store the value type in the Bundle
so that it can be reproduced when reading. Earlier we were assuming only
String and String[].

This change disables all atrace tracing in Zygote immediately after it is
initialized. This is necessary because Zygote has no way to receive
notifications that the enabled trace tags have been changed. Tracing is
re-enabled when other processes fork from Zygote.
