Sympton:
When application crash in a special timing and system server's InputMethodManager is binding, deadlock may occur.
Root Cause:
Thread(1): When using InputMethodManager in system server, it will lock mH(handler) of InputMethodManager,
and sometimes it will call to InputMethodManagerService::showCurrentInputLocked and will call bindService at some condition,
then it will also lock ActivityManagerService.
Thread(2): When an application crashed, it will lock ActivityManager when showing crash dialog, inside the dialog,
it will call setEnabled of Button and lock mH of InputMethodManager.setEnable of TextView will lock IMM's handler.
So the deadlock happened as the flow: (2) lock AMS -> (1)lock mH -> (2)wait mH -> (1) wait AMS
Solution:
Reduce nested lock of error dialog: post message to let (2) lock mH after release AMS lock.

Root Cause:
Use removeTask with flag ActivityManager.REMOVE_TASK_KILL_PROCESS will set waitingToKill = "remove task"
to the target process when its setSchedGroup is not BG_NONINTERACTIVE.
Later the target process may be killed when applying oom-adj due to setSchedGroup has changed to BG_NONINTERACTIVE.
If the process is needed to restart, the process record will be resued.
Then the restarted process may be killed again because its waitingToKill is not null.
Solution:
Clean waitingToKill when process is dead.

Symptom: Unable to kill by Am again and will be skipped updating its oom adj.
Root Cause:
A restarted process will reuse original process record.
The flag killedByAm will keep previous state.
Solution:
Reset the flag killedByAm to false when the process is started.

Root Cause:
When there is only home activity existed,
updating home apk will call forceStopPackageLocked to finish the activity.
Then activity history becomes empty, then home will be launched,
but its package is still target to close that results a loop.
Solution:
If home activity has been force-stopped, do not stop the same home activity again.

Prior support forced all third party apps
to be resolved against the default stanza
of the mac_permissions.xml file when assigning
seinfo labels. This meant that all third party
apps, in effect, were untrusted regardless of
cert and therefore received the same selinux domain.
This also had the unfortunate side effect of forcing
certain third party apps into the wrong domains
because of shared userid requests among apps.
This patch removes that restriction and instead
allows all apps, regardless of location, to be
matched against the full mac_permissions.xml
policy file. This then allows all apps signed
with known good certs to receive the same selinux
domains of other apps with whom they share trust.

There was lax / incomplete error checking around the
construction of Apk handles. This change changes the ApkHandle
API and makes it throw IOException if the zipfile couldn't
be opened.
Additionally :
- Fix a resource leak in DefaultContainerService
- Report errors correctly during package moves.

Add getTetheredDhcpRanges() interface and call it before calling
mNwService.startTethering() to update dhcp ranges. This will allow p2p app
to run well concurrently with other tethering app(e.g. usb tethering).

If all activities of a given stack were finishing, no activity was
marked as front-of-task. This confused ActivityManager, so make sure
there's always exactly one activity marked as front-of-task.

We don't want directories like profiles and the former
profile-cache from being included in the prune. SELinux would
have prevented the move, but that's very brittle.

This allows callers to force an install to a particular
ABI. This is intended only for testing (and CTS) and is
not meant for usage by the installer package.

The property ro.hardware.gps can be specifid to allow a single system
image to work with differrent GPS chips. The HAL layer will use it to load
/system/lib/hw/gps.<ro.hardware.gps>.so. Add support to GpsLocationProvider
to use the same property to find /etc/gps.<ro.hardware.gps>.conf, falling
back to /etc/gps.conf if the property is not set or the file is not present.

Check that each package from the setting has
a parsed pkg before we attempt to perform dex-opt
on it. If it doesn't have a parsed package, adjust
the ABI in the settings, but don't perform dexopt.
It will be dexopted later if it's still active
based on the setting.

The key improvement is that we need to keep track of
the package that's currently being scanned (this includes
new installs and upgrades of existing packages) and treat
it specially. If we didn't do that, In the case of upgrades
we would perform the shared UID calculation based on the ABI
of the old package, and not the current package.
This change also allows us to perform the CPU ABI calculation
before dexopt, which saves us from having to do it twice and
fixes a bug where we were using the wrong package path to
dexopt a package.
This also has the side effect of fixing 15081286.
