fb: finally fix carrier lable shows on first boot sometimes

Issue:
- boot up
- directly open via fast QS pulldown QS
- sometimes carrier label is shown

Expected behaviour: should not show

Fix: Visibility is directly set when the settings observer is registered first time.
If no update was done on the carrier label before the user pulled QS down the first time
it showed up. Vary rare case that this can happen
but should be handled. To fix it do not set the visibility directly and call the
updateCarrierAndWifiLabelVisibility(boolean) method to handle the correct visibility.

As well last cleanup on notification shorcuts...move the check if it is
active or not to the visbility method itself. Way cleaner

And remove the previous attempt to fix the above described issue due
it did not fix it at all

MediaFocusControl: Deny audio focus if notification stream is 0

Previously audio focus would be granted regardless of notification
volume, meaning that if notifications are muted the media stream would
still be dimished for focus. By checking if STREAM_NOTIFICATION is 0 and
if a notification stream is requesting focus, this is no longer an issue.

Set Settings.Global.WIFI_SCAN_ALWAYS_AVAILABLE default value

To be able to customize the "WiFi scan always available"
setting we need to set a default value.

Harden against transiently unavailable backup transports

The init & clear operations are particularly important to ensure
delivery when at all possible, so we retry those periodically
if the transport is unavailable when we first attempt them.

Now with 100% less build break.

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.

Only send storage intents after boot complete

It is not possible to send a broadcast before the system
boot is completed. If you do it anyway you will get an
IllegalStateException: Cannot broadcast before boot completed.

If a memory card is inserted or removed while the phone is
booting up, there is a risk that the MountService will try to
broadcast a storage intent too early, and cause the device
to crash.

Use FLAG_RECEIVER_REGISTERED_ONLY_BEFORE_BOOT to avoid
problems with too early broadcasts.
