onAccountsUpdated shouldn't be called back after listener unregistered

There is a problem of AccountManager that onAccountsUpdated() is
called back even after the OnAccountsUpdatedListener is unregistered.
It may cause application crash.

For example, when rotating a tablet 180 degree with Settings apk
running, com.android.settings.Settings is re-launched 2 times
successively. (Destroy->Create->Destroy->Create)
It repeats adding&removing OnAccountUpdatedListener.

When dialog was being opened in the following cases,
NullPointerException at BackStackRecord.getBreadCrumbTitle()
was happened on 10 inch tablet which has 2 panes on Settings.
* Settings > Language&input > Language
* Settings > Language & input > Text-to-speech output > Speech rate
* Settings > Wi-Fi > Menu > Advanced > Keep Wi-Fi on during sleep
* Settings > Wi-Fi > Menu > Wi-Fi Direct > Rename device

This fix prevents the undesirable callback.

Fix to NullPointerException when activity is relaunched

When ChooseTypeAndAccountActivity is relaunched and resumed
by ActivityManager a call is made to onActivityResult without
first triggering onResume. This leads to mAccounts object
still being null.

Fixed by properly setting mAccounts object if it is null prior
to use after function onCreate has been called.

FLAG_PRIVILEGED disappears if privileged app is updated and rebooted

Since Kitkat, an app pre-loaded under /system/priv-app/ has
FLAG_PRIVILEGED. However, if the app updated and the device
rebooted, privileged flag is unset from pkgFlags. This patch
fix issue to assign privileged flag when scanning the updated
packages.

Webkit: add to support file uploading

This change adds one function in WebChromeClient for supporting
uploading file in browser. In Android 4.4, browser is based on
chromium not webkit engine, chromium engine support uploading file
and will callback to client to show file chooser, but android_webview
client has empty implementation within this callback for file chooser.

So we solve this issue by adding implementation in framework chromium
client which extends android_webview client, function in framework
webkit client and corresponding functions in browser app.

Perform NTP lookup at Mobile data connections

If NITZ isn't supported by the current carrier the Android framework
relies instead on a remote NTP server to set the system clock. The
NetworkTimeUpdateService class polls for NTP time during the first 4
minutes after boot, failing to get NTP time within these minutes will
increase the polling interval to 24 hours. Hence, if a data connection
isn't activated directly after boot it can take a long time for the
system clock to be updated. To prevent this situation, NTP lookup is
scheduled as soon as a Mobile data connection has been established.
