Fix for ambiguous and broken disk formatting dialog

This patch ensures that the path-string from StorageNotification is converted
to the appropriate StorageVolume so that it can be correctly passed to the
formatting class. It also displays this path to the user so that it is clear
what will be deleted.

While trying to use a USB flash drive over OTG, the drive's FS somehow got
corrupted, so Android gave me a notification to re-format it. Okay, so then
a dialog pops up that doesn't specify what volume/device it will format, and
I incorrectly assumed it would be the USb drive. However this activity defaults
to the main internal memory for some reason, and wiped my data. Thank God for
them internets... (Dropbox)

SystemUI: always use transparent notification shade

Devices with less than 512MB of memory have a solid
black notification shade. Remove the isHighEndGfx()
check to force a transparent notification shade on
all devices.

Keyguard: Reduce font size of clock in status keyguard (sw720dp)

When system clock is configure for a 24H clock, times like 22:22, overflows the clock
of the keyguard status view on sw720dp. This change reduces the font size of clock to
allow to fit all time formats.

Prevent audio players starting on startup.

Previously, (at least) Apollo was started on startup (in that it
appeared in the notification bar) because it listens to the AUDIO_BECOMING_NOISY
intent to silence itself in that case. This intent is broadcast by
AudioService when there's a user switch to silence any potential audio
players for the old user. As the system also sends around a
USER_SWITCHED intent on startup, this led to the aforementioned player
startup.
As the intent of AudioService was to act on a user backgrounding anyway,
send out AUDIO_BECOMING_NOISY as reaction to a USER_BACKGROUND intent
instead of the USER_SWITCHED intent.
