Telephony: Add support for NETWORK_TYPE_GSM

Add support for NETWORK_TYPE_GSM in TelephonyManager and
corresponding mapping in ServicState.java so that when
application queries getVoiceNetworkType() and currently
camped rat is GSM, they get network mode as GSM instead
of network mode unknown.

Signal strength: add more checks to signal strength,

so it doesn't fall under the range of poor signal and automatically
assumes a gsm signal, actually checks if all values are true and not
valid then pass it on to lte or gsm. This fixes cases when gsm signal
is not valid and lte is active. When lte is active and shows a really
weak and gsm signal is not avalible due some broken vendor ril or
just running cdma lte and a few others senario creates this issue.

Telephony: Add TD-SCDMA network modes

1)TD-SCDMA Signal Strength support.
2)Add TD-SCDMA network type support in MobileDataStateTracker class
to identify TD-SCDMA as UMTS variant and use the relevant
kernel data stack tcp buffer sizes defined.
3) Add TD-SCDMA to the list of supported network modes.

Dispatch keys to a device specific key handler

Injects a device key handler into the input path to handle additional
keys (as found on some docks with a hardware keyboard).

Configurable via overlay settings config_deviceKeyHandlerLib and
config_deviceKeyHandlerClass.

DeviceKeyHandle: The device should consume only known keys

When the device receive the key, only should consume it if the device
know about the key. Otherwise, the key must be handle by the active app.
Also make mDeviceKeyHandler private (is not useful outside this class)

DeviceKeyHandler : Allow handling keyevents while screen off

Some devices require the keyevents to be processed while the screen
is off, this patchset addresses that by moving the filter up in the call
hierarchy.

fb: respect config_animateScreenLights and fade out if set to true

Currently if config_animateScreenLights is set to true the settings entry is not shown
but the default animation is not fade out which it should be in this case.

This commit fixes this.

Use a content observer for getting the default APN

Instead of executing a query of the database for the
default APN on every network state change, an observer
is used on the database to be notifited when the apn
has changed. This prevents unneccesary queries on the
the database.

SignalStrength: Hotfix TD-SCDMA 1 + 2

These checks need to be reviewed, they're making unwarranted assumptions
about signal value formats and possible tech combos.
This appears to work for all possible scenarios I was able to test,
but the "LTE checks" shouln't be necessary at all.

AudioService: Show safe volume panel for non-interactive volume adjustments

If safe volume is active, apps calling mp.setVolume() to adjust the
headset to a value higher than the threshold will have the operation
fail silently because no volume dialog is active to pop up the
"do you wish to override" question.
This is particularly bad for peripherals that use the audio jack
(Square readers, Jawbone bands), since they usually require levels
close to maximum for proper communication and the app isn't prepared
to deal with a silent rejection of the requested volume.
