We now keep track of all of the active start operations per
non-system process, so they can be cleaned up if the process
goes away.

The default Alarm Manager behavior for KLP+ apps will be to aggressively
coalesce alarms, trading exact timeliness of delivery for minimizing the
number of alarm-delivery points, especially wakeup points.
There is new API in AlarmManager, setExact() and setExactRepeating(),
for use by apps that absolutely *must* get their alarms at a specific
point in time.

These new constants are a better mapping to the kind of
information that procstats is wanting to collect about
processes. In doing this, the process states are tweaked
to have a bit more information that we care about for
procstats.
This changes the format of the data printed by procstats,
so the checkin version is bumped to 2. The structure is
the same, however the codes for process states have all
changed. The new codes are, in order of precedence:
p -- persistent system process.
t -- top activity; actually any visible activity.
f -- important foreground process (ime, wallpaper, etc).
b -- important background process
u -- performing backup operation.
w -- heavy-weight process (currently not used).
s -- background process running a service.
r -- process running a receiver.
h -- process hosting home/launcher app when not on top.
l -- process hosting the last app the user was in.
a -- cached process hosting a previous activity.
c -- cached process hosting a client activity.
e -- cached process that is empty.
In addition, we are now collecting uss along with pss
data for each process, so the pss checkin entries now
have three new values at the end of the min/avg/max uss
values of that process.
With this switch to using process state constants more
fundamentally, I realized that they could actually be
used by the core oom adj code to make it a lot cleaner.
So that change has been made, that code has changed quite
radically, and lost a lot of its secondary states and flags
that it used to use in its computation, now relying on
primarily the oom_adj and proc state values for the process.
This also cleaned up a few problems -- for example for
purposes of determing the memory level of the device, if a
long-running service dropped into the cached oom_adj level,
it would start being counted as a cached process and thus
make us think that the memory state is better than it is.
Now we do this based on the proc state, which always stays
as a service regardless of what is happening like this, giving
as a more consistent view of the memory state of the device.
Making proc state a more fundamentally part of the oom adj
computation means that the values can also be more carefully
tuned in semantic meaning so the value assigned to a process
doesn't tend to change unless the semantics of the process
has really significantly changed.
For example, a process will be assigned the service state
regardless of whether that services is executing operations
in the foreground, running normally, or has been dropped to
the lru list for pruning. The top state is used for everything
related to activities visible to the user: when actually on
top, visible but not on top, currently pausing, etc.
There is a new Context.BIND_SHOWING_UI added for when system
services bind to apps, to explicitly indicate that the app
is showing UI for the system. This gives us a better metric
to determine when it is showing UI, and thus when it needs
to do a memory trim when it is no longer in that state. Without
this, services could get in bad states of continually trimming.
Finally, more HashSet containers have been changed to ArraySet,
reducing the temporary iterators created for iterating over
them.

The activity manager now keeps a new "process state" for
each process, indicating the general execution and memory
state of the process. This closely follows the out-of-memory
adjustment and scheduling class that it currently tracks,
but roles these together (plus a little more info) into one
more semantically meaningful number.
This value is reported to each process as it changes, so they
can do things like tune the Dalvik garbage collector to match
the current process state.
I think I should also switch to this for process states. It
will give is more meaningful divisions of time for each process.
Also fix a problem in the activity stack where the previous
process was not being set correctly when moving between
activity stacks.

The new location monitoring op is to tell us when an application

- New Activity.reportFullyDrawn() method that applicatins can call
when they know they are fully drawn, allowing us to have better
app launch time info. This data is also included in usage stats.
- Added total and free memory data "dumpsys meminfo".
- Tuned the moderate memory levels to be more aggressive about
considering the device getting low on RAM, and thus starting
to prune RAM from processes.
- Fixed issues in processstats when reading old data as well as
resetting and other various fixes.

The activity manager now uses some heuristics to try to
sample PSS data from processes so that it can get enough
data to over reasonable time have something useful, without
doing it too aggressively.
The current policy is:
1. Whenever a significant global change happens (memory state,
sceen on or off), we collect PSS from all processes; this will
not happen more than every 10 minutes.
2. When all activities become idle, we will collect PSS from the
current top process; this will not happen more than every 2
minutes per process.
3. We will sample the top-most process's PSS every 5 minutes.
4. When an process's oom adj changes and it has been more than
30 minutes since PSS has been collected from it, we will
collect a new PSS sample.
5. If a process changes from service A to service B (meaning it
has been running a service for a long time), we will collect
a PSS sample from it.
6. If someone explicitly requests PSS data (for running services
UI or dumpsys), record that.
Also:
- Finish moving the procstats output all to the new format.
- Record information about processes being killed due to excessive
wake locks or CPU use in procstats.
- Rework how we structure common vs. per-package process stats to
make it simpler to deal with.
- Optimize the Debug.getPss() implementation (we use it a lot now).
Should probably optimize it further at some point.

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.
