1. Now a user state has ins own spooler since the spooler app is
running per user. The user state registers an observer for the state
of the spooler to get information needed to orchestrate unbinding
from print serivces that have no work and eventually unbinding from
the spooler when all no service has any work.
2. Abstracted a remote print service from the perspective of the system
in a class that is transparently managing binding and unbinding to
the remote instance.
3. Abstracted the remote print spooler to transparently manage binding
and unbinding to the remote instance when there is work and when
there is no work, respectively.
4. Cleaned up the print document adapter (ex-PrintAdapter) APIs to
enable implementing the all callbacks on a thread of choice. If
the document is really small, using the main thread makes sense.
Now if an app that does not need the UI state to layout the printed
content, it can schedule all the work for allocating resources, laying
out, writing, and releasing resources on a dedicated thread.
5. Added info class for the printed document that is now propagated
the the print services. A print service gets an instance of a
new document class that encapsulates the document info and a method
to access the document's data.
6. Added APIs for describing the type of a document to the new document
info class. This allows a print service to do smarts based on the
doc type. For now we have only photo and document types.
7. Renamed the systemReady method for system services that implement
it with different semantics to systemRunning. Such methods assume
the the service can run third-party code which is not the same as
systemReady.
8. Cleaned up the print job configuration activity.
9. Sigh... code clean up here and there. Factoring out classes to
improve readability.

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.

System server always forks from Zygote so we no longer need
the system_server executable which was probably broken anyhow.
This makes the initialization sequence slightly more intelligible.
Likewise, we don't need the GrimReaper anymore because init
will automatically take care of restarting the system when the
service manager dies.

We were allowing the system and the shell user to access use the
screen introspection APIs but the root user was not able to to so.
This change enableS the root user to also use these APIs. Note that
we usually allow the root user to access privileged functionality
similarly to the shell user of the system.

fixScale(float) method has been extracted from the code but the original
code has been kept in place. Because of this, the animation scale is
"fixed" twice which is not necessary. This patch, simply call
fixScale(float) once and stores the result of it in the scale variable.

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.

This change exposes couple of internal APIs to enable TDLS between local
machine and a remote machine. The implementation translates client provided
remote IP to a MAC address using system ARP cache, and then instructs the
driver to enable TDLS with that endpoint. Another API takes application
specified MAC address.

On stacked interfaces like 464xlat, Legacy VPN can't find the
default gateway because it uses getRoutes, which only returns
routes for the base link and not for the stacked links. It also
assumes that the interface that the default route points to is
the interface for the base link (e.g., rmnet0) instead of the
interface the route actually points to (e.g., clat4).
Fix this by calling getAllRoutes to find the default IPv4 route,
and get the interface name from the route we find instead of
assuming it's the base interface.

The new location monitoring op is to tell us when an application
is monitoring for any location changes. It may be useful information
in addition to the more explicitly information about when location
data actually goes to the app.
Also make parts of AppOpsManager public for use by gcore. It is
not available to third party apps.
